Description

The present invention relates to a registration system.

Information about real estate owners and objects is managed through real estate registration, and since the registry is publicly available, the objects and rights can be clearly understood. For example, even a third party can understand information such as the location and area of land and buildings by viewing the registry. It is also possible to know who the owner of the real estate is and how the ownership was transferred. Even for movable property, the vehicle registration number of a general vehicle is registered at the Land Transport Bureau, and the specifications and rights of the vehicle to be registered can be understood. For construction machinery, vehicle-type machinery with a license plate, like general vehicles, is registered at the Land Transport Bureau and a vehicle inspection certificate showing the details of the machine is issued, so the rights of the owner can be understood by checking the registration at the Land Transport Bureau.

On the other hand, for construction machinery that has an individual identification number but does not have a vehicle inspection certificate issued by a public agency, a written transfer certificate is issued by the Japan Construction Machinery Manufacturers Association, and this transfer certificate is used to transfer ownership. Specifically, when a construction machinery manufacturer manufactures a construction machinery and sells it to a purchaser, the certificate contains information such as the manufacturer's name and address and the model number of the construction machinery in question, as well as the name and address of the purchaser, proving that the construction machinery in question has been transferred from the manufacturer to the purchaser, i.e., that the ownership of the construction machinery has been transferred from the manufacturer to the purchaser. Whenever the owner changes, the information of the new owner (i.e. the transferor) is added to the transfer certificate (see Figure 3). This transfer certificate cannot be reissued, so by checking the transfer certificate, in addition to information such as the model number of the construction machinery, you can find out who the current owner is and how the machinery has been transferred to the present.

Incidentally, because the value of the machinery itself is high, construction machinery is recognized as having value as movable property collateral, and is used by financial institutions and finance companies when transferring construction machinery, as well as when signing lease agreements. For this reason, a transfer certificate, which certifies who the owner of the construction machinery is and proves its transfer, is extremely important.

Despite the fact that construction machinery transfer certificates are extremely important, there are no regulations regarding how they should be stored. As a result, transfer certificates may be kept by the owner, the manufacturer, or the leasing company, and as of now there is no way to confirm the existence of an official transfer certificate, leading to rampant fraud through the counterfeiting of transfer certificates.

As a system for registering information on construction machinery, Patent Document 1 discloses a heavy machinery online information provision system and method that encourages emergency deployment of heavy machinery in the event of a disaster and utilization of idle heavy machinery during peacetime. Patent Document 1 discloses a system configuration that provides a database of heavy machinery providers and users and is capable of providing search results for information on heavy machinery. However, the technology in Patent Document 1 is merely a means of registering information on heavy machinery owned by heavy machinery manufacturers, heavy machinery leasing companies, etc., and does not mention managing the transfer certificates for the registered heavy machinery, that is, the heavy machinery owned by heavy machinery manufacturers, heavy machinery leasing companies, etc.

On the other hand, Patent Document 2 discloses a service (management service) for managing various types of information, including the registration and acceptance of changes to various types of information, a service (output service) for outputting various documents, ledgers, histories, etc., and a service (viewing service) for enabling users to search for and view various types of information (paragraph 0020 of the specification of Patent Document 2, Figure 1).
Furthermore, Patent Document 2 discloses the registration and modification of various information, the registration of the maintenance history and inspection history (medical record information) of the construction machinery, and the issuance of a "digital transfer certificate" which is a certificate regarding the transfer of the construction machinery (paragraph 0023 of the specification of Patent Document 2).
Furthermore, a "digital transfer certificate" is issued by the service provider, and then the transferor and transferee of the construction equipment are subsequently written (data input) in the same manner as an endorsement of a promissory note, so that the owner of the construction equipment can be accurately identified. It is also stated that this service makes it possible to prevent or deter fraudulent buying and selling of construction equipment (paragraph 0023 of the specification of Patent Document 2).

JP 2005-338989 A JP 2020-30548 A

The technology in Patent Document 2 may be able to prevent or deter unauthorized buying and selling of construction machinery, but the technology in Patent Document 2 cannot be adopted unless a new system of digital registration is established. In other words, it is not possible to prevent unauthorized buying and selling of construction machinery while maintaining the current registration management system based on paper transfer certificates.

In view of the above circumstances, the present invention aims to provide a registration system that can manage the registration of rights and prevent the forgery of rights while maintaining the existing system of using paper certificates.

The registration system of this embodiment is a system for registering and managing rights such as ownership of construction machinery and the like based on registration documents and certificates issued on paper, and is capable of preventing the forgery of ownership rights, etc.

The registration system of this embodiment is suitable for managing the registration of ownership of construction machines to prevent counterfeiting, but it can also be used to prevent counterfeiting of rights of any movable property for which a registration document, certificate, appraisal certificate, etc., including paper information for identifying an individual item such as the serial number of the item, is issued. For example, the system can be used to register and manage rights of automobiles, luxury watches, jewelry, etc., in addition to construction machines.
In the following, a case where the ownership of a construction machine is registered and managed will be explained as a representative example.

<About the transfer certificate>
Before describing the details of the registration system 1 of this embodiment, a brief description will be given of the construction machine transfer certificate used for verification by the registration system 1 of this embodiment.

The transfer certificate is issued by the Japan Construction Machinery Manufacturers Association and is a document with a hologram or other means to prevent forgery. It is a document that cannot be reissued and contains information to identify the construction machine, such as the model number of the construction machine, the name and address of the construction machine manufacturer that produced the construction machine, and is stamped with the seal of the construction machine manufacturer. This transfer certificate is signed (or stamped) with the name and address of the purchaser (transferor) who purchased the construction machine from the construction machine manufacturer, and the transferor's official seal (registered seal (representative seal) in the case of a corporation) or other seal that certifies the transferor is stamped below the signature of the construction machine manufacturer (see Figure 3). In other words, the transferor listed at the bottom of the transfer certificate indicates the current owner. If the transferor does not have an official seal, the transferor will also sign their name and address. When the construction machine is transferred, a new transferor, that is, the new owner, is added to the bottom of the transfer certificate, so the transfer certificate can identify the current owner and keep track of past owners and their changes in ownership.

The registration system 1 of this embodiment registers and manages the ownership of construction machinery, but can prevent forgery of ownership by utilizing the written transfer certificate described above. In other words, the registration system 1 of this embodiment can effectively prevent forgery of ownership by forging a transfer certificate while utilizing the current written management to transfer ownership by transfer and to certify the current owner, and also allows the registration information of construction machinery to be effectively utilized.

In the following explanation, "transfer certificate image data" refers to image data of the paper transfer certificate mentioned above. For example, the "transfer certificate image data" is image data created by scanning the transfer certificate with a scanner or the like, or data taken of the transfer certificate with a digital camera or the like, which is saved as image data (see Figure 3).

<Registration System 1 of the Present Embodiment>
First, a schematic configuration of a registration system 1 according to the present embodiment will be described.
As shown in FIG. 1, a registration system 1 of the present embodiment includes an information processing device 10 and a plurality of terminal devices 20 capable of data communication with the information processing device 10 .

The terminal device 20 is capable of data communication with the information processing device 10 via a network NW or the like. This terminal device 20 has a function of, for example, requesting information from the information processing device 10 and displaying information provided by the information processing device 10. Examples of terminal devices 20 include general personal computers, tablet terminals, and mobile terminals such as smartphones.

<Functions of the information processing device 10>
2, the information processing device 10 has a communication unit 11 that performs data communication with the terminal device 20 via a network NW or the like, a storage unit 12 that stores various data, and a viewing unit 13 that views information stored in the storage unit 12. The information processing device 10 also has a verification unit 15 that verifies documents such as transfer certificates. The information processing device 10 also has a control unit 30 that controls the operation of each unit of the information processing device 10 so that the registration system 1 of this embodiment performs functions as described below.

<Communication unit 11>
The information processing device 10 has a communication unit 11 having a function of transmitting and receiving data between the information processing device 10 and the terminal device 20, that is, a function of performing data communication between the information processing device 10 and the terminal device 20. The communication unit 11 is not particularly limited as long as it has a function of performing data communication between the information processing device 10 and the terminal device 20. For example, the communication unit 11 may include a communication module corresponding to a wired or wireless LAN (Local Area Network) standard for connecting to a network NW, or a module corresponding to a mobile communication standard such as LTE (Long Term Evolution), 4G (4th Generation), or 5G (5th Generation). The communication unit 11 may also have a communication module corresponding to a short-range communication standard or specification such as Bluetooth (registered trademark), AirDrop (registered trademark), IrDA, ZigBee (registered trademark), Felica (registered trademark), or RFID. Of course, the communication unit 11 may include a plurality of communication modules, such as a communication module compatible with a wired or wireless LAN standard, a module compatible with a mobile communication standard, and a communication module compatible with a short-range communication standard or specification.

<Control Unit 30>
As described above, the control unit 30 has a function of controlling the operation of each unit (communication unit 11, storage unit 12, browsing unit 13, verification unit 15) of the information processing device 10. The control unit 30 also has a function of displaying an operation screen (function selection screen) for operating the registration system 1 of this embodiment. The control unit 30 also has a function of displaying a screen (function operation screen) for operating the selected function when a user who uses the registration system 1 of this embodiment selects a function displayed on the function selection screen.

For example, when the registration system 1 of this embodiment is operating, the control unit 30 displays a function selection screen on a display or the like connected to the information processing device 10, or transmits a signal to display the function selection screen to the terminal device 20. On this function selection screen, buttons indicating the functions of the above-mentioned units (e.g., view, verify, etc.) and an input field for inputting the function to be selected are displayed.

In the following explanation, the term "displaying on a display, etc." may be used to refer to a screen such as a function selection screen, both when it is "displayed on a display, etc." and when it is "displayed on the screen of the terminal device 20."

When a button included in a function selection screen displayed on a display or the like is selected by using an input device (e.g., a keyboard, a mouse, etc.) connected to the information processing device 10 or by touching a screen, or when predetermined information is input into an input field or the like included in the function selection screen displayed on a display or the like by an input device connected to the information processing device 10, the control unit 30 causes a function operation screen for operating the functions corresponding to each button or the input information to be displayed on the display or the like. This function operation screen displays buttons showing the processes to be performed by the selected function, input fields for inputting the processes to be performed, etc.

Note that in the following, when referring to a button displayed on a function selection screen, etc., "selecting a button included in the function selection screen displayed on a display, etc. by using an input device (e.g., a keyboard, mouse, etc.) or touching the screen" may simply be referred to as "selecting a button" or "selecting." Additionally, "inputting predetermined information into an input field, etc. included in the function selection screen displayed on a display, etc. by an input device connected to the information processing device 10" may simply be referred to as "inputting information." Furthermore, "selecting a button" and "inputting information" may be combined and referred to as "inputting."

The control unit 30 also has a function of causing each unit to execute the selected process when the user selects a process included in a function selection screen displayed on a display or the like. For example, when the function selection screen is displayed on a display or the like and a button displayed on the function selection screen is selected or information is input, the control unit 30 causes each unit to execute a process based on the selected button or the input information.

Furthermore, the control unit 30 may have a function to determine whether or not to permit use of the registration system 1 of this embodiment. For example, when the registration system 1 of this embodiment is started up, the control unit 30 may have a function to display a screen requesting input of an ID, a password, etc. for using the registration system 1 of this embodiment on a display or the like connected to the information processing device 10 before displaying a function selection screen on the display or the like. In addition, when a signal requesting connection is supplied from the terminal device 20 to the information processing device 10 while the registration system 1 of this embodiment is started up, the control unit 30 may have a function to transmit a signal to the terminal device 20 to display a screen (user authentication screen) requesting input of information identifying a user such as an ID and a password for using the registration system 1 of this embodiment (hereinafter referred to as user identification information). In this case, the control unit 30 is provided with a function to display a function selection screen on a display or the like, or transmit information for displaying a function selection screen on the screen of the terminal device 20 through the transmission unit 11, when the user identification information input from the input device or terminal device 20 connected to the information processing device 10 matches the information stored in the storage unit 12.

<Storage unit 12>
The storage unit 12 has a function of storing information necessary for the registration system 1 of this embodiment to function. The information stored in the storage unit 12 includes the above-mentioned user identification information and basic information in which the machine information data and the transfer certificate image data, which is the image data of the transfer certificate of the construction machine (see FIG. 3), are associated and stored (see FIG. 4). The machine information data includes machine information, which is various information related to the construction machine (for example, information written on the vehicle inspection certificate of the construction machine, the model number of the construction machine, etc.). The storage unit 12 includes a first storage unit 12a in which basic information is stored, and a second storage unit 12b connected to the first storage unit 12a and storing all or part of the basic information stored in the first storage unit 12a. The storage unit 12 has a function of changing information such as the user identification information and basic information stored in the first storage unit 12a in response to a command from the control unit 30. The storage unit 12 also has a function of supplying information stored in the second storage unit 12b to the browsing unit 13, the verification unit 15, etc. in response to a command from the control unit 30. The details of the storage unit 12 will be described later.

<Viewing Section 13>
The viewing unit 13 has a function of viewing information stored in the second storage unit 12b of the storage unit 12. The viewing unit 13 has an input function 13a, an information request function 13b, and a screen display function 13c. The screen display function 13c has a function of displaying an input screen for inputting information to be viewed from the input function 13a (input screen display function), and a function of displaying information provided based on a request from the information request function 13b (information display function). When the viewing function is selected on the above-mentioned function selection screen, the viewing unit 13 executes the input screen display function of the screen display function 13c, the input function 13a, the information request function 13b, and the information display function of the screen display function 13c in this order, in response to a command from the control unit 30. The functions of the viewing unit 13 will be described below.

The input screen display function of the screen display function 13c has a function of displaying an input screen for inputting information to be viewed from the input function 13a on a display or the like in response to a command from the control unit 30. For example, when the viewing function is selected on the function selection screen, a command (input screen display command) is sent from the control unit 30 to the screen display function 13c instructing it to display the input screen on a display or the like. When the screen display function 13c receives the input screen display command, it displays the input screen on a display or the like. The input screen is a screen for inputting information that the user of the registration system 1 of this embodiment wishes to view. This input screen may be stored by the screen display function 13c, or may be stored in the memory unit 12, and when the input screen display command is sent, the control unit 30 may read it from the memory unit 12 and send it together with the input screen display command or send it included in the input screen display command.

The input function 13a is a function 13a by which a user of the registration system 1 of this embodiment inputs information that the user wishes to view. This input function 13a has a function of selecting and inputting information to be viewed while the input screen is displayed on a display or the like. For example, if a button for selecting information is provided on the input screen, the input function 13a has a function of inputting the information to be viewed by the user US selecting the button. Also, if a box for the user US to input, for example, a model number, construction machine name, owner name, etc. is displayed on the input screen, the input function 13a has a function of inputting the information to be viewed by inputting information into the box.

The information request function 13b has a function of requesting information stored in the second memory unit 12b of the memory unit 12 based on information input from the input function 13a. For example, when a button related to specific information (such as the name of a construction machine or the name of a manufacturer) is selected in the input function 13a, the information request function 13b has a function of supplying the control unit 30 with a browsing request signal requesting information associated with the information of the button. In addition, when a model number of a construction machine is input from the input function 13a, the information request function 13b has a function of supplying the control unit 30 with a browsing request signal requesting information associated with the model number. Furthermore, when there is an input requesting only specific information among the information associated with the model number of a construction machine, the information request function 13b has a function of supplying the control unit 30 with a browsing request signal requesting only the specific information. Then, when the browsing request signal is supplied from the information request function 13b to the control unit 30, the control unit 30 has a function of reading information (browsing information) corresponding to the information included in the browsing request signal from the second memory unit 12b of the memory unit 12 and transmitting it to the screen display function 13c.

The information request function 13b may have a function of supplying the viewing request signal directly to the second memory unit 12b of the memory unit 12, without supplying it to the control unit 30. In this case, information corresponding to the information included in the viewing request signal (viewing information) may be sent directly from the second memory unit 12b of the memory unit 12 to the screen display function 13c, without going through the control unit 30.

The aforementioned screen display function 13c has a function of displaying the viewing information sent from the control unit 30 or the second memory unit 12b of the memory unit 12 on a display or the like as the viewing result. For example, when a construction machine name is selected from the input function 13a, the viewing information corresponding to that construction machine name is displayed on a display or the like as the viewing result. When construction machines with the same construction machine name but different model numbers are stored, all construction machines with different model numbers can be displayed as a list on a display or the like (see Figure 5 (B)). In addition, when a specific model number is input from the input function 13a, each piece of information for the construction machine with that model number can be displayed on a display or the like (see Figure 4).

Note that a screen such as a list displayed on a display as a result of browsing may function as an input screen. For example, as shown in FIG. 5(B), when multiple construction machines with the same construction machine name but different model numbers are displayed on a display as a list of browsing results, the input function 13a allows the model number in the list to be selected. Then, a browsing request signal requesting information on the construction machine with that model number is generated by the information request function 13b, and browsing information on the construction machine display with that model number is sent to the screen display function 13c, so that each piece of information on the construction machine with that model number can be displayed on a display. For example, in FIG. 5(B), when a grayed-out field is selected, basic information on the construction machine with the corresponding model number (see FIG. 4) may be displayed as browsing information.

Since each function of the viewing unit 13 has the above-mentioned functions, the user can view the desired information contained in the basic information by selecting the viewing function on the function selection screen and performing the specified operations and inputs.

The screen display function 13c of the viewing unit 13 may have a function of hiding a part of the viewing information sent from the control unit 30 or the second memory unit 12b of the memory unit 12, that is, the information requested for viewing by the input function 13a, in the case of transfer certificate image data in which the basic information includes the viewing information. For example, when the transfer certificate image data is viewed and a signature or a seal impression is displayed on a display, there is a possibility that a forged document will be created based on a copy of the displayed image or an image captured from the screen. Therefore, when a request is made to view the transfer certificate image data, it is desirable to not display parts of the transfer certificate image that are important for verification by the verification unit 15, such as the signature or seal impression and hologram (see FIG. 6). For added security, the transfer certificate image data may not be viewable.

<Verification Unit 15>
As shown in FIG. 2, the information processing device 10 includes an image acquisition unit 14, which is a device having a function of forming image data from a document (hereinafter, sometimes referred to as a document for verification), such as a scanner or a digital camera. The verification unit 15 has a function of judging whether the document for verification is the original document of the transfer certificate, that is, whether the document for verification is the genuine document of the original document. The verification unit 15 includes a verification image formation function 15a, an image verification function 15b, and a judgment function 15c. When the verification function is selected on the function selection screen described above, the verification unit 15 executes the verification image formation function 15a, the image verification function 15b, and the judgment function 15c in this order, in response to a command from the control unit 30. The function of the judgment function 15c will be described below. The "transfer certificate image" corresponds to the "original certificate image" in the claims.

The verification image forming function 15a has a function of operating the image acquisition unit 14 to form verification image data in response to a command from the control unit 30. For example, when the verification function is selected on the function selection screen, the control unit 30 transmits a command (image acquisition command) to the verification image forming function 15a to operate the image acquisition unit 14 to form verification image data. The verification image forming function 15a that has received the image acquisition command displays a screen (image acquisition screen) for acquiring a verification image on a display or the like. The image acquisition screen includes a command to place the verification document at a predetermined position of the image acquisition unit 14 (i.e., a position where an image of the document can be acquired), a button for performing image acquisition, a box for inputting information that identifies the verification document (such as the number of the transfer certificate or the model number (serial number) of the construction machine), and the like. Then, after setting the verification document at a predetermined position of the image acquisition unit 14, when the user selects the button for performing image acquisition, the image acquisition unit 14 forms verification image data for the verification document. The formed verification image data is supplied from image acquisition unit 14 to verification image formation function 15a (or control unit 30), and is supplied from verification image formation function 15a (or control unit 30) to image verification function 15b together with information identifying the verification document. Note that since the verification document usually includes information identifying the verification document, a box for inputting information identifying the verification document may not be provided, and verification image formation function 15a or image verification function 15b may acquire information identifying the verification document.

The image verification function 15b has a function of comparing the transfer certificate image data included in the basic information with the verification image data, and verifying whether or not the two match. For example, when the verification image data is supplied from the verification image forming function 15a (or the control unit 30) to the image verification function 15b, the image verification function 15b obtains basic information having information for identifying the verification document from the second storage unit 12a of the storage unit 12 based on information for identifying the verification document transmitted together with the verification image data (or information for identifying the verification document obtained from the verification image data). When the basic information is obtained, the transfer certificate image data is selected from the basic information, and the transfer certificate image data is compared with the verification image data. That is, the image of the verification image data and the image of the transfer certificate image data are compared by a known method such as pattern matching, and the matching state of the two images is verified to create the verification result. The verification result calculated by the image verification function 15b is not particularly limited. For example, the image verification function 15b can create the verification result by expressing the degree of matching between the transfer certificate image data and the verification image data as a score, a matching ratio (percentage), or the like. The calculated verification result is supplied from the image verification function 15b to the determination function 15c together with the verification image data and information specifying the verification document.
In addition, it is desirable for the image verification function 15b to have the function of displaying an error message or a message instructing the user to register new basic information when there is no basic information corresponding to the information identifying the verification document or when the basic information corresponding to the information identifying the verification document does not include transfer certificate image data.

The judgment function 15c is a function that judges whether or not the document that is the source of the verification image data is the original document that is the source of the image of the transfer certificate image data based on the result of the comparison and verification by the image verification function 15b. For example, when the verification result is transmitted from the image verification function 15b, the judgment function 15c judges whether or not the verification result is a legitimate original document based on a predetermined threshold value or the like, and displays the judgment result on a display or the like. The method by which the judgment function 15c judges whether or not the transfer certificate is legitimate is not particularly limited. For example, when the image verification function 15b outputs the verification result as a score, a method can be adopted in which a method is ...
In addition, even if the verification document is a legitimate transfer certificate, verification may become difficult if it becomes dirty or the like due to long-term use. Therefore, the determination function 15c may determine as a determination result that the transfer certificate is highly likely to be a legitimate transfer certificate or that the transfer certificate is low in possibility, in addition to determining that the transfer certificate is a legitimate transfer certificate or that the transfer certificate is a fake.

Since the verification unit 15 has the functions described above, it can accurately determine the authenticity of the verification document.

For example, in the case of a transfer certificate for construction machinery, the name and address of the purchaser (transferor) who purchased the construction machinery from the construction machinery manufacturer is signed (or stamped), and the transferor's official seal (or, in the case of a corporation, its registered seal (representative seal)) or other seal certifying the transferor is stamped below the construction machinery manufacturer's signature (see Figure 3). It is difficult to perfectly match the signature characters and seal impression on the original transfer certificate with those on a document that is a forged version of the original. In addition, as a new transferor's signature or seal is added each time construction machinery is transferred, the signature characters and seal impressions increase, making it even more difficult to forge the original. Therefore, the image data (verification image data) of the transfer certificate acquired by the image acquisition unit 14 by the verification image formation function 15a is compared and verified by the image verification function 15b with the image data (transfer certificate image data) of the original transfer certificate included in the basic information to verify whether a matching image is included, and the degree of match is determined by the judgment function 15c, making it possible to accurately judge the authenticity of the paper transfer certificate.

The image verification function 15b may compare the entire transfer certificate image and the verification image to determine whether they match, or may determine whether the image of an important and characteristic part of the transfer certificate image (certification information image) that is important for judging the transfer certificate matches the transfer certificate image and the verification image. For example, in the case of a transfer certificate of a construction machine as shown in FIG. 3, if the image of the transfer certificate number, model, serial number, and the part with the signature or seal of the construction machine manufacturer or transferor is used as the certification information image, the verification time can be shortened compared to the case of comparing the entire image, and the verification accuracy can be improved because the image area to be compared can be limited. The certification information image may be determined in advance, or the user may be allowed to determine the certification information image by the verification image formation function 15a. When the certification information image is determined in advance, the certification information image may be stored in the transfer certificate image data of the basic information together with the entire image data. When the user determines the certification information image by the verification image formation function 15a, the image verification function 15b is provided with a function for searching for a part of the transfer certificate image that corresponds to the certification information image. For example, if the document being certified is a transfer certificate for construction machinery, the certification information image may include the transfer certificate number, model, serial number, the areas where the manufacturer or transferor has signed or stamped, a hologram of the transfer certificate, etc.

In addition, multiple certification information images as described above may be provided, and the image verification function 15b may create a comparison verification result for each certification information image. For example, the transfer certificate number, model, serial number, signature location, seal location, and hologram may each be set as separate certification information images, and verification may be performed for each certification information image, and a verification result may be created for each. Then, only if all the verification results have a predetermined degree of agreement or higher, may the verification document be determined to be the original document of the transfer certificate. Note that, when multiple certification information images are provided, it is desirable to also verify the relative positions of each certification information image.

In addition, the method of comparing and verifying the image of the verification image data and the image of the transfer certificate image data can be the general pattern matching or template matching method described above, but the two images can also be compared and verified using AI (artificial intelligence). In particular, when a signature or a seal impression is used as the certification information image, the degree of agreement between the two images can be verified with high accuracy by comparing and verifying using AI (artificial intelligence). For example, when comparing an original document and a verification document, if the comparison and verification is performed using AI (artificial intelligence), slight misalignment of the seal impression or the signature, as well as blurring of the seal impression or signature, and differences in shading can be recognized, so that the accuracy of determining whether the document is a forgery can be improved. In addition, by having the handwriting of the signer learned, handwriting analysis can be performed, so it is also possible to verify whether the person who signed the original document is the person in question. For example, if a third party signs the original signature without permission and creates a transfer certificate, the verification document will be the original document itself. However, if handwriting analysis is performed, it is possible to detect that the transfer is a forgery even if the verification document itself is an original document. This will make it possible to determine whether the transfer contract is valid even if the original document is stolen.

<Operation of the registration system 1 according to the present embodiment>
The registration system 1 of this embodiment has the above-mentioned configuration and therefore exhibits the following functions.

First, when the registration system 1 of this embodiment (hereinafter sometimes simply referred to as the registration system 1) is activated and a connection is made to the registration system 1 from the terminal device 20, the control unit 30 displays a user authentication screen. When user identification information is entered from this user authentication screen, the registration system 1 becomes available for use, and the control unit 30 displays a function selection screen. When a function to be used is selected from the function selection screen, the control unit 30 or each unit displays a function operation screen for each function. Then, each function becomes available for use.

For example, when the viewing function is selected, an input screen is displayed on a display or the like by the screen display function 13c of the viewing function, and the user can select and input information about the construction machine that he or she wishes to view from the input screen. When specific information or the like is input, the information about the construction machine that he or she wishes to view is requested from the second storage section 12b of the storage section 12 by the information request function 13b. Then, in response to the request, the information about the construction machine that he or she wishes to view is transmitted from the second storage section 12b of the storage section 12 to the screen display function 13c. Then, a list of information about the construction machine that he or she wishes to view is displayed on a display or the like by the screen display function 13c, and the user can view the desired information.
Furthermore, if the user selects information displayed on a display, etc., the selected information is further displayed on the display, etc., by processing similar to that described above, allowing the user to view details of the selected information.

When the verification function is selected, a process of forming image data of a verification document such as a transfer certificate is started. That is, the verification image forming function 15a forms the verification image data by scanning or photographing a document such as a transfer certificate using the image acquisition unit 14. Information identifying the verification document is also input from the verification image forming function 15a. When the verification image data is formed, the verification image data and information identifying the verification document are sent to the image verification function 15b, and the image verification function 15b acquires corresponding basic information from the second storage unit 12b of the storage unit 12 based on the information identifying the verification document. When the basic information is acquired, the image verification function 15b compares and verifies the transfer certificate image data included in the basic information with the verification document, and creates a verification result. When the verification result is created, the verification result is sent from the image verification function 15b to the judgment function 15c, and the judgment function 15c judges whether the verification document is a legitimate original document based on the verification result, and displays the judgment result on a display or the like. Therefore, by using the verification function, the user can determine whether a document such as a transfer certificate is an original document or a forgery. In the registration system 1 of this embodiment, the verification unit 15 compares the data formed from the verification document with the data of the original document of the transfer certificate stored in the memory unit 12 to determine authenticity, making it possible to prevent forgery while still using existing methods that use documents. Therefore, it is possible to clarify the location of rights even for construction machines currently in circulation, and to prevent forgery of ownership.

<Regarding the storage unit 12>
As described above, the storage unit 12 is provided with a first storage unit 12a and a second storage unit 12b connected to the first storage unit 12a.

The first memory unit 12a stores basic information, which is data that associates various pieces of information related to construction machines with each other. The basic information is information that associates and stores machine information data (see FIG. 4), which includes machine information, which is various pieces of information related to construction machines, with transfer certificate image data, which is image data of the transfer certificate for the construction machine (see FIG. 5(A)). This basic information is provided for each machine, and basic information for multiple machines is stored in the first memory unit 12a as a basic information list.

The second storage unit 12b stores information provided by the first storage unit 12a. Although the second storage unit 12b receives information from the first storage unit 12a, it cannot request information from the first storage unit 12a or request changes or additions to stored information. In other words, the second storage unit 12b has the function of receiving information unilaterally from the first storage unit 12a, changing the supplied information to new information if the supplied information has already been stored, and additionally storing the information if the supplied information is newly supplied information. Furthermore, the second storage unit 12b can provide stored information in response to requests from each unit, but cannot or is limited in changing the stored information through operations from each unit.

In this way, the memory unit 12 provides information stored in the second memory unit 12b, which provides information upon request from each unit, at the time of browsing or verification, but the information cannot be changed or is limited, and information is in principle supplied unilaterally from the first memory unit 12a to the second memory unit 12b. Because of this configuration, the registration system 1 of this embodiment has a system configuration that makes it difficult for information such as basic information stored in the first memory unit 12a of the memory unit 12 to be tampered with, thereby ensuring the safety of the basic information and increasing its reliability.

In particular, if the first memory unit 12a of the memory unit 12 is used as a private blockchain node, the basic information will be distributed and shared among all nodes, making it even more difficult to tamper with the basic information and further increasing the safety and reliability of the basic information.

Note that if the memory unit 12 has the first memory unit 12a and the second memory unit 12b as described above, the safety and reliability of the basic information can be increased, but the memory unit 12 does not necessarily have to have the second memory unit 12b. Even in this case, the first memory unit 12a provides information in response to requests from each unit, but safety and reliability can be maintained if changes to and additions to the basic information, etc., cannot be made or are limited in response to requests from each unit. In this case, safety and reliability can be increased by making the first memory unit 12a a node of a private blockchain.

The machinery information included in the basic information is not particularly limited, and various information can be included in the basic information as machinery information. Examples of machinery information include information listed on the construction machinery's vehicle inspection certificate, the model number of the construction machinery, the name and address of the manufacturer, and the names and addresses of current and past owners. The machinery information may also include the repair history of the construction machinery, the numbers of the various parts that make up the construction machinery and their replacement history, etc. This machinery information data can be, for example, data in which the model number of each construction machinery is associated with the above-mentioned machinery information in a list, as shown in Figure 4.

In addition, if the transfer certificate image data is stored as a history not only of the latest transfer certificate image data but also of past transfer certificate image data, it is possible to more accurately verify whether the verification document is the original document. In other words, if the verification unit 15 compares all past transfer certificate images with the current verification image, it is possible to more accurately verify the authenticity of the verified verification document.

The verification image acquired by the image acquisition unit 14 may also be included in the basic information of the first memory unit 12a of the memory unit 12 in association with the transfer certificate image. For example, the verification unit 15 or the control unit 30 is provided with a function for creating verification implementation data that associates the verification image, information on the transfer certificate image compared and verified with the verification image (e.g., the model number of the construction machine, etc.), the date and time of the verification, and information on the user who performed the verification, and a function for transmitting the verification implementation data to the first memory unit 12a of the memory unit 12 after the verification is completed. In addition, when the verification implementation data is transmitted from the verification unit 15 or the control unit 30 to the first memory unit 12a of the memory unit 12, a function for adding the verification implementation data to the basic information corresponding to the information on the transfer certificate image included in the verification implementation data is provided. By providing such a function, for example, it is possible to know when and who tried to verify the transfer certificate of the construction machine. Then, if the document on which the verification image is based is a forged document, it is possible to quickly determine that the document is a forged document and who possesses it, and therefore damage caused by forgery can be quickly prevented and forgery can be suppressed more effectively. As described above, the information supplied from the verification unit 15 or the control unit 30 is not added to the basic information in the first storage unit 12a of the storage unit 12 immediately after the information is supplied, but is preferably temporarily stored in a temporary holding folder or the like in the first storage unit 12a of the storage unit 12, and the administrator AD uses the information change unit 16 described below to determine whether the supplied information needs to be added or changed.

The basic information may also include information regarding the current location of the construction machine and information regarding the assessed value of the construction machine.
If information on the current location of the construction machine is included, the procurement of the construction machine can be carried out easily and reliably. For example, a contractor who wants to use a construction machine with a specified performance in a certain location can use the browsing function of the registration system 1 of this embodiment to input the construction machine with the desired performance and the location where the machine is to be used. This allows the contractor to identify construction machines that are close to the desired location and have the specified performance, allowing the contractor to procure the construction machine efficiently. Moreover, since the basic information also includes information on past owners and repair history, it is also possible to predict problems with the construction machine to be procured.
Furthermore, if the basic information includes information on the assessed value of the construction machine, it is possible to easily and reliably grasp whether the price and asset value of the construction machine to be purchased are appropriate. For example, when negotiating the purchase of a certain construction machine, the browsing function of the registration system 1 of this embodiment is used to input and view the functions, model, years of use, etc. equivalent to that of the construction machine. This makes it possible to quickly and easily determine whether the price offered by the transferor of the construction machine to be purchased is appropriate. Furthermore, since the asset value of the construction machine to be purchased can be grasped, by providing the viewed information, it becomes easier to obtain financing from financial institutions such as leasing companies and banks, and the financial institutions can also reduce the risk of financing.
In particular, when the assessed value of a construction machine is viewed, the assessed value stored in the basic information is initially displayed, but once viewing begins, the price (current price) of the same model, etc. of construction machine on the secondhand market automatically searched or acquired by AI or the like via the Internet may be displayed. This allows the viewer to grasp the current price in a timely manner, making it possible to create purchase plans, make sales contracts, and obtain loans at a fair price.
When viewing, the current price may be displayed instead of the appraisal price stored in the basic information from the beginning.
Furthermore, when viewing is terminated, the viewing unit 15 may have a function of sending a command (a valuation change command) requesting a change to the valuation amount stored in the basic information to the control unit 30. In this case, the control unit 30 may be provided with a function of changing the valuation amount stored in the basic information automatically or with approval from the administrator AD when the valuation change command is received.

<Information Changing Unit 16>
The registration system 1 of this embodiment has an information change unit 16 that has a function of directly changing and adding basic information stored in the first storage unit 12a of the storage unit 12. As described above, in the storage unit 12, each function acquires information stored in the second storage unit 12b, and the second storage unit 12b stores information such as basic information provided from the first storage unit 12a. However, the second storage unit 12b provides the information stored at the time of browsing or verification, but the information cannot be changed or is limited. By configuring in this way, the registration system 1 of this embodiment has a system configuration that makes it difficult for the basic information to be tampered with. However, when a new transferor is added to the transfer certificate, it becomes necessary to update the transfer certificate image included in the basic information. In addition, there are also cases where basic information of a new construction machine is added. Therefore, the registration system 1 of this embodiment has an information change unit 16 that can be operated only by a restricted administrator AD, etc., and allows the basic information stored in the first storage unit 12a of the storage unit 12 to be changed and added without restriction, while preventing problems such as tampering with the basic information.

<Digital transfer certificate creation and management function>
The registration system 1 of this embodiment is based on an existing system for verifying transfer, for example, a system for guaranteeing and verifying the owner and its change by using a written transfer certificate in the case of construction machinery. The registration system 1 of this embodiment may have a function for creating a digital transfer certificate associated with basic information and managing ownership by the digital transfer certificate. In other words, in addition to managing ownership by a written transfer certificate, it may be possible to manage ownership by the digital transfer certificate.

For example, when a construction machine manufacturer newly manufactures a construction machine, the information change unit 16 is provided with a function of inputting information such as the manufacturer's name, address, and model number of the target construction machine into the information change unit 16, creating new basic information corresponding to the model number of the construction machine, and adding the basic information (new basic information) registered in the first memory unit 12a of the memory unit 12 to the basic information list. Then, when the new basic information is added to the basic information list, the information change unit 16 is provided with a function of creating digital transfer certificate data associated with the new basic information. Then, when the digital transfer certificate data is created, the information change unit 16 is provided with a function of adding information such as the purchaser's name and address to the digital transfer certificate data. Also, when a construction machine registered in the digital transfer certificate is transferred, the information change unit 16 is provided with a function of adding the transferee to the digital transfer certificate. With this configuration, even if it is a new construction machine, it is possible to reliably know who the owner is and the transfer of ownership, so that the registration system 1 of this embodiment can manage ownership using a digital transfer certificate.

In this case, if the first memory unit 12a of the memory unit 12 in which the basic information is stored is a node of a private blockchain, it will be difficult to tamper with the digital transfer certificate, even if it is digital data that can be copied and modified more accurately and easily than a written document. Therefore, even if ownership is managed using a digital transfer certificate, its safety and reliability can be increased.

The information change unit 16 may have a function to check whether the transferor or transferee of the digital transfer certificate is registered as a transferor or transferee in the basic information list of another construction machine, and if so, to search and display the transaction history. If the information change unit 16 has such a function, the transaction history can be provided to the transferor or transferee, which can encourage the transferor or transferee to consider a transfer contract, thereby improving the security of the transaction. For example, if it can be confirmed that the transferor or transferee of a transaction of a construction machine registered in a written transfer certificate is a transferor or transferee, it can be determined that the transferor or transferee is a safe and reliable trading partner. In other words, if the registration system 1 of this embodiment, which manages ownership rights in writing, manages ownership rights using digital transfer certificates, the security of ownership management and its transfer transactions can be improved.

In addition, in the case of a transferor or transferee who cannot be found in the past transaction history, the information change unit 16 may have a function to confirm the transferor or transferee. For example, a list of companies with criminal histories or that have caused accidents in other transactions (a risky trader list) may be registered in the first memory unit 12a of the memory unit 12, and the information change unit 16 may be provided with a function to search for transferors or transferees who cannot be found in the past transaction history to see if they are included in that list. This can reduce the possibility that the transferor or transferee will become involved in a risky transaction.

Note that if the viewing unit 13 has a function to search for transaction history by entering a company name, etc., the information changing unit 16 does not necessarily need to have a function to search and display transaction history.

<Digital cancellation certificate creation and management function>
The registration system 1 of this embodiment may have a function of deleting the registration of ownership and proving that the registration has been deleted. In other words, the registration system 1 may have a function of creating and issuing a digital deleting certificate that proves that the registration has been deleted. For example, when a construction machine is exported overseas, it is necessary to delete the registration in Japan, and the construction machine can be exported overseas on the premise of deleting the registration. Therefore, when a construction machine to be exported overseas is registered in the registration system 1 of this embodiment, a function is provided for inputting information for deleting the registration into the information change unit 16 and adding the deleting information to the basic information. For example, a function is provided for adding the user who registered the deleting, the date of the deleting registration, the reason for the deleting, etc., to the basic information as the deleting information. Then, by browsing the basic information, it is possible to prevent troubles such as negotiating the transfer or making a purchase contract for a construction machine that no longer exists in Japan, and therefore the safety of the transaction can be improved.
If the information change unit 16 is provided with a function for generating a digital certificate of cancellation that proves that the registration has been cancelled when the cancellation information is registered, the cancellation can be easily and quickly confirmed using the digital certificate of cancellation. This makes it possible to quickly proceed with overseas exports while increasing the security of transactions.
It is preferable that even if deletion information is registered for a certain construction machine, the deletion information is simply added to the basic information of the construction machine and the basic information of the construction machine is stored as is in the basic information list. This makes it possible to grasp the past information of the construction machine even after the deletion information is registered. Also, even if deletion information is once registered, it becomes easy to restore the registration, and the continuity of information j from before deletion to after re-registration can be maintained.

The registration system of the present invention is also suitable as a system for managing the registration of ownership of various movable property for which written registration certificates and certificates are issued, in addition to construction machinery.
