The communication unit 10 controls data communication with a host device such as a host computer (not shown).

Next, a description will be given of how a banknote that has been stolen is inserted into the ATM and collated with a database of theft information. FIG. 3 shows a state in which an ATM is destroyed and a safe inside (also referred to as a banknote cartridge) is stolen. As shown in FIG. 3, a case is considered in which the ATM 30 of the bank (A bank), which is some method, is destroyed by the criminal and the banknote cartridge 31 inside is stolen. In this case, banknotes in the cartridge are dyed with antitheft ink by the antitheft ink ejecting function inside the banknote cartridge 31. The anti-theft ink ejecting function includes, for example, an opening / closing lid 310 provided in the longitudinal direction of the banknote cartridge 31, an ink tank 311 provided in the ATM 30, and a sensor unit 312 physically and electrically connected to the ink tank 311. The anti-theft ink ejecting mechanism having a pipe 313 connecting the ink tank 311 and the opening / closing lid 310 is realized. When the sensor unit 312 having the shake detection sensor detects the shake of the ATM 30, the opening / closing lid 310 is opened and the anti-theft ink is ejected from the ink tank 311. The anti-theft ink ejection mechanism is not limited to this, and various conventionally known techniques can be applied.

Suppose that the banknote 32 with anti-theft ink is held by the criminal or has been released and found in some form. When the banknote 32 with the anti-theft ink is inserted into the ATM 1 in which the function of this embodiment is supported by the criminal himself or another person and a transaction act is performed by the transaction operation, the banknote processing unit 4 is provided with the anti-theft ink. The banknote 32 is conveyed to the banknote identification part 11 of FIG. 1, and it is identified whether it is a genuine note. At that time, the banknote image 33 is an example of the case where the serial number portion is infiltrated with the anti-theft ink, but the banknote recognition unit 11 recognizes the banknote with the anti-theft ink based on the characteristics of the read main image and the like.

The banknote identification unit 11 stores identification log data including information such as a serial number in the storage unit 9 as a record of detecting a banknote with anti-theft ink. At this time, the banknote recognition unit 11 assumes a case such as a banknote image 33 in which the serial number cannot be read with the anti-theft ink, and extracts a border line between the banknote frame and the part infiltrated with the antitheft ink and the part not infiltrated. Then, it is converted into a small-capacity image 34 (for example, a binarized image) to reduce the image capacity. The bill identifying unit 11 stores an ID indicating a pre-registered estimated manufacturer and device candidate that is soaked in a pattern that is closest to and most similar to the feature of the converted bill image 34 together with the journal data. To remember.

Thus, the banknote identification part 11 is the banknote image 34 which binarized the banknote image 33 for every banknote 32 with anti-theft ink other than information, such as a serial number, and the banknote from which the banknote image 34 was obtained. Is stored in the storage unit 9 in association with IDs that are candidates for the ATM 30 including the banknote cartridge 31 that stores the bill. FIG. 3 shows that two candidates of candidate 1 ID “12345678” and candidate 2 ID “234456789” are stored together with the banknote image 34 as examples of the IDs as candidates. The candidate ID is stored in advance in the storage unit 9 in association with a banknote image indicating a typical anti-theft ink pattern obtained by the manufacturer's ATM identified by the ID. The data stored in the storage unit 9 in advance is identification log data accumulated in the host computer 36 as will be described later. The banknote recognition unit 11 stores the identification log data and the journal data in the storage unit 9 in association with each other.

ATM1 periodically sends the stored identification log data to the host computer 36 connected via the network N. The host computer 36 receives from the various ATMs including ATM1 via the network N. The identified log data is stored in the database 35 as a transaction log. Since this process is performed, if it is found that banknotes with anti-theft ink remain in the cartridge or are traded, even if there is no serial number record of when the banknote was deposited, identification of the theft source, etc. It is possible to provide an environment that can handle this. The database 35 is a database 35 such as a theft information, and information such as an infiltration example of the anti-theft ink ejected by the ATM of a bank that has been stolen for various ATMs connected to the network N includes the identification log. Stored in the data. In the host computer 36 or the computer 37 connected to the host computer 36 or the ATM 1 via the network N, the ID included in the identification log data stored in the database 35 and the identification log data received from the ATM 1 are included. Using the included ID as a key, the image of the ID is collated. As a result, even if the serial number cannot be read, information candidates such as a banked ATM or a stolen safe can be listed.

Specifically, with reference to FIG. 3, in bank B ATM 1 into which banknotes with antitheft ink have been inserted, the banknote recognition unit 11 reads the banknote image 33 of the banknotes 32 with antitheft ink. The banknote with the anti-theft ink is a banknote stored in an ATM banknote cartridge 31 of Bank A that has been destroyed or stolen. When the banknote recognition unit 11 reads the banknote image 33, the banknote identification unit 11 converts the image into a binarized banknote image 34. The banknote recognition unit 11 stores the banknote image 34 and the candidate ID in the storage unit 9 in association with each other. For example, the banknote identification unit 11 transmits the banknote image 34 to the host computer 36, and the host computer 36 specifies a banknote image indicating a pattern of the anti-theft ink that is most similar to the banknote image 34 from the database 35. The candidate ID corresponding to the specified banknote image is transmitted to ATM1. In this process, a banknote image having a certain degree of similarity, such as a banknote image similar to the next most similar banknote image, is included as a candidate, and the ID corresponding to the banknote image is transmitted to ATM1. May be.

Thereafter, the banknote recognition unit 11 transmits identification log data in which the candidate ID received from the host computer 36 is associated with the banknote image 34 to the host computer connected via the network N.

When the host computer 36 receives the identification data from the ATM 1, the host computer 36 compares the received identification log data with the identification log data stored in the database 35 so far, and the identification log data stored in the database 35. The banknote image which shows the pattern of the anti-theft ink most similar to the banknote image 34 contained in the received said identification log data is specified among the banknote images contained in ID, and both are collated. In general, the collation result here is the same as when the ATM 1 specifies the candidate ID of the banknote image indicating the anti-theft ink pattern most similar to the banknote image 34. The host computer 36 transmits the banknote image specified by the collation and the candidate ID stored in the database 35 in association with the banknote image to the computer 37 connected via the network N.

Further, the host computer 36 uses the ID as a candidate included in the identification log data received from the ATM 1 as a key, and uses the same ID as the candidate ID included in the identification log data stored in the database 35. Search for. The host computer 36 generates a banknote image obtained by merging and synthesizing both banknote images corresponding to the searched ID. The synthesis of banknote images can be realized, for example, by calculating the average of the differences between the boundary lines formed in both banknote images and generating a banknote image using the calculated boundary lines as new boundary lines. . The host computer 36 updates the identification log data including the ID stored in the database 35 to the identification log data in which the synthesized banknote image and the candidate ID are associated with each other.

Thus, whenever the banknote image 34 is obtained in ATM1, identification log data including the banknote image 34 and the candidate ID is transmitted to the host computer 36, and the database 35 is updated, so that it is stored in the database 36. It is possible to improve the accuracy of the identification log data being recorded, and to improve the accuracy of identification and identification of the candidate ID and bill image by the host computer 36.

The computer 37 displays the banknote image specified by the verification received from the host computer 36 and the candidate ID on a display unit such as a display, and activates editing software to print it out on a predetermined sheet. .

In the above description, the database 35 is held on the host computer side, but may be held on the ATM side. In this case, access to the host computer 35 is not required when specifying the candidate ID.

Next, FIG. 4 shows a characteristic example of the ejection trace of the anti-theft ink. A soaking example 40 of the type in which the anti-theft ink is ejected in the banknote longitudinal direction is an example of a banknote image when the anti-theft ink ejected in the safe or the banknote cartridge is ejected in the longitudinal direction of the banknote. Further, the soaking example 41 of a type in which the anti-theft ink is ejected in the short direction of the banknote is an example of a banknote image when the anti-theft ink ejected in the safe or the banknote cartridge is ejected in the short direction of the banknote. Depending on the type of the bill cartridge 31, the anti-theft ink may be ejected in both the longitudinal direction and the lateral direction. For this reason, these features may be included in the identification log data and stored in the database 35.

FIG. 5 is a diagram illustrating an example of identification log data of a normal genuine note in which the anti-theft ink is not attached to the banknote inserted from the ATM 1.

As shown in FIG. 5, the identification log data stored in the storage unit 9 is data including serial number information, anti-theft ink adhesion information, anti-theft ink boundary image information, and banknote ID with anti-theft ink. The serial number information is information including an image of the serial number portion included in the banknote image and the serial number. The anti-theft ink adhesion information is a flag indicating that no anti-theft ink was detected. The anti-theft ink boundary image information is a small-capacity image file (for example, banknote image 34) indicating a portion where the anti-theft ink is attached and a portion where the anti-theft ink is not attached. As for the anti-theft ink boundary image information, the front surface and the back surface are stored. The banknote ID with anti-theft ink is the candidate ID. If it is recognized that the anti-theft ink is not attached, the main image only stores a rectangular image representing the shape of a banknote. The bill ID with anti-theft ink is set to Null or an initial value indicating that there is no candidate.

In the example shown in FIG. 5, it can be seen that the anti-theft ink is not detected in the inserted banknote with the serial number “12345567890”, and Null or “00000000” is stored as the initial value in the banknote ID with the anti-theft ink.

Next, FIG. 6 is a diagram showing an example of identification log data of a genuine note to which anti-theft ink is attached so that the banknote inserted from ATM 1 can read the serial number.

As shown in FIG. 6, the identification log data stored in the storage unit 9 is the same as that shown in FIG. 5, but “ON” is stored in the anti-theft ink adhesion information and the anti-theft ink is detected. It is shown that. Further, the binarized ink boundary image information stores a binarized image similar to the banknote image 34 shown in FIG. 3, and the candidate for identifying the candidate of the manufacturer of the ATM that has ejected the bank theft-proof ink. It is shown that two IDs are stored.

In FIG. 6, together with the “ON” information and the banknote image 34, two IDs “00000021” and “00000035” are stored as candidates, and each is manufactured by “Manufacturer A”. It can be seen that “a device” is “b device” manufactured by “manufacturer B”. The name of the manufacturer may be stored in advance in the storage unit 9 in association with the candidate ID. Further, for example, the number of the candidates can be determined by the host computer 26 according to the identification result based on the threshold when the degree of coincidence of the banknote images is 90% or more, or 75% or more. For example, when the degree of coincidence between the banknote image included in the identification log data stored in the database 35 and the banknote image included in the identification log data received from ATM 1 is 90%, When one candidate ID is obtained and the degree of coincidence is 75%, more candidate IDs are obtained as identification results based on the threshold.

Next, FIG. 7 is a diagram showing an example of identification log data of a genuine note to which anti-theft ink is attached so that the banknote inserted from ATM 1 cannot read the serial number.

As shown in FIG. 7, the identification log data stored in the storage unit 9 is the same as that shown in FIG. 6, but all the digits of the serial number cannot be read. For this reason, the serial number is stored as serial number information such as Null or partially read numbers, characters, symbols, and the like. Further, the flag indicating that the anti-theft ink has been detected is stored in the anti-theft ink adhesion information, and the binarized image similar to the banknote image 34 shown in FIG. 3 is stored in the anti-theft ink boundary image information. Are stored, and two IDs that are candidates for identifying the candidates of the manufacturer of the ATM that sprayed the anti-theft ink on the banknote are stored.

In FIG. 7, together with the “ON” information and the banknote image 34, the serial number “123 ***” (or Null) in which some digits have not been read, and “00000014” as the candidate ID. , “00000002” are stored as candidates, and it is understood that “a device” manufactured by “manufacturer B” and “b device” manufactured by “manufacturer D”, respectively. The method of determining the manufacturer name and the number of candidates can be considered in the same manner as in FIG.

If a banknote with anti-theft ink is identified, the banknote cannot be traded. Therefore, the banknote with the anti-theft ink is stored in the banknote cartridge of the ATM 1 that has been inserted, and the staff collects the banknote determined to be the banknote with the anti-theft ink at a timing such as after the scheduled time. In this case, it can be easily guessed that it is managed in an envelope other than the genuine note for subsequent analysis or investigation. FIG. 8 is a diagram illustrating an example of handling a real anti-theft ink banknote. In the management envelope 80, a note of when and where the ATM 1 is installed is written down by a person in charge at the branch where the ATM 1 is installed. Turned. In FIG. 8, it is described as the memorandum that the banknotes were stolen banknotes inserted at xx month xx day xx hour xx minutes at B bank b1 branch.

At this time, in the management envelope 80, an identification sheet 82 on which the candidate ID of the ATM manufacturer presumed to contain the stolen banknote and the banknote image 34 corresponding to the ID is written. Is affixed. This identification sheet 82 is output from, for example, a printer connected to the computer 37 shown in FIG. By outputting such an identification sheet 82 from the computer 37 and pasting it on the management envelope 80 by the maintenance staff, the stolen banknote can be easily managed.

In the above description, the case where the identification paper 82 is output from the printer connected to the computer 37 has been described. However, the ATM 1 receives the output data of the identification paper 82 from the host computer 26, and the bill recognition unit 11 is connected to the ATM 1. May be output from the printer.

Next, the operation of ATM1 will be described. FIG. 9 is a flowchart showing the operation 90 of ATM1. The ATM 1 receives the user's operation according to the screen instruction in the display / operation unit 3 and performs a transaction process (s91).

FIG. 10 shows a banknote identification process (s101) executed at the time of banknote conveyance, a process (s92) for storing the identification result, and a process related to storage of information when the anti-theft ink is attached (S103, in the transaction process performed in s91). s104, s105, s106) and an identification log storage process (s107) for leaving a transaction record after identification.

The banknote identification unit 11 performs the banknote identification process in the process of s101, and then temporarily stores the identification result in a memory (not shown) in s102 (s102). In the identification process, the image of the banknote being conveyed is read, and information such as the banknote image 33 and the denomination and serial number of the banknote is stored.

The banknote recognition unit 11 determines whether or not the sensor 110 has detected the attachment of the anti-theft ink in the process of s103 (s103), and determines that the sensor 110 has not detected the attachment of the anti-theft ink (s103). No), the process proceeds to the storage process of identification log data (s107).

On the other hand, when the banknote identification part 11 determines with the sensor 110 having detected adhesion of anti-theft ink (s103; Yes), it converts the banknote image 33 identified by s102 into the binarized banknote image 34, and memorize | stores it. The information is temporarily stored in the unit 9 (s104).

The banknote recognition unit 11 transmits the banknote image 34 to the host computer 36, and the host computer 36 displays the banknote image indicating the pattern of the anti-theft ink that is most similar to the banknote image 34 (or a candidate thereof) in the database 35. The candidate is searched and specified, and the candidate ID corresponding to the specified banknote image is transmitted to ATM 1 (s105).

Thereafter, the banknote recognition unit 11 transmits the identification log data in which the banknote image 34 is associated with the candidate ID received from the host computer 35 to the host computer connected via the network N. When the host computer 36 receives the identification data from the ATM 1, the host computer 36 compares the identification log data with the identification log data stored so far in the database 35, and is included in the identification log data stored in the database 35. The banknote image showing the pattern of the anti-theft ink most similar to the banknote image 34 included in the received identification log data is identified and collated with each other (s106).

The identification log data is stored in the storage unit 9 in a predetermined layout (for example, FIGS. 5 to 7) in s107 (FIG. 11), which will be described later. At this stage, the same setting as in FIG. 11 is performed.

The banknote recognition unit 11 stores the identification log data associated in s106 in the storage unit 9 (s107). This process will be described later with reference to FIG.

The host computer 36 uses the ID as a candidate included in the identification log data received from the ATM 1 in s106 as a key, and uses the same ID as the candidate ID included in the identification log data stored in the database 35. , And a banknote image obtained by merging and synthesizing both banknote images corresponding to the searched ID is generated. The host computer 36 updates the identification log data including the ID stored in the database 35 to the identification log data in which the combined banknote image and the candidate ID are associated with each other (s108).

Furthermore, the host computer 36 sends the banknote image specified by the collation in s106 and the candidate ID stored in the database 35 in association with the banknote image to the computer 37 connected via the network N. Then, the computer 37 displays the banknote image identified by the collation received from the host computer 36 and the candidate ID on a display unit such as a display in the layout shown in FIG. 8, for example, and starts the editing software By doing so, it is printed out on a predetermined sheet (for example, identification sheet 82) with the same layout (s109).

FIG. 11 is a flowchart showing information processing related to anti-theft ink in the storage processing of the identification log in s107.

First, the banknote identification unit 11 sets initial values of storage areas of serial number information, serial number image, anti-theft ink adhesion information, and anti-theft ink boundary image information (s111). The serial number information is set to an initial value convenient for the program such as character information padded with Null or *, the serial number image is set to information indicating no recording, and the anti-theft ink adhesion information is set to OFF (the anti-theft ink). Set the flag of “not detected”. Information indicating no recording is set in the anti-theft ink boundary image information.

Next, the banknote identification part 11 determines whether the serial number was able to be read from the identification result (s112), and when it determines with the serial number not being able to be read (s112; No), it is the next step with an initial value. Proceed to On the other hand, when it is determined that the serial number could not be read (s112; Yes), the banknote identification unit 11 records all or some of the serial numbers that can be read, and the serial number obtained by cutting out the serial number portion that was read simultaneously. An image is recorded (s113).

The banknote recognition unit 11 determines whether or not the anti-theft ink is detected from the identification result (s114), and determines that the anti-theft ink is not detected (s114). No), the process proceeds to the next step with the initial value. On the other hand, when it is determined that the anti-theft ink is attached (s114; Yes), the banknote identification unit 11 sets the anti-theft ink attachment information to ON (indicating that the anti-theft ink is attached) and sets the anti-theft ink border image. Information (a reduced-capacity front image and back image) is stored (s116). Here, the banknote image 34 temporarily stored in s104 may be stored. Moreover, the banknote identification part 11 records banknote ID with anti-theft ink, complete | finishes the recording process regarding anti-theft ink, and complete | finishes the storage process of an identification log through the completion | finish process of the remaining identification log, etc. (s117). By executing such processing, the identification log data is stored in the layout as shown in FIGS.

In the above-described embodiment, it is assumed that the banknote with theft-proof ink is obtained in some form and traded at ATM1 without knowing that the banknote with theft-proof ink is with the criminal himself or with theft-proof ink. However, if banknotes with anti-theft ink are brought to the counter or found in some form and there are many banknotes with anti-theft ink in one place, transaction processing of these banknotes with anti-theft ink at once using this ATM1 By doing this, it is possible to acquire the anti-theft ink boundary image information of each banknote, and to use it for the analysis of the theft source.

Also, in the above embodiment, registration of banknote IDs with anti-theft ink is performed in the transaction process (s91). However, if the transaction processing cannot be executed due to reasons such as insufficient processing time required for the transaction, the processing of s105 to s109 is performed at a predetermined timing after execution of the transaction processing (for example, nighttime batch processing outside business hours). It may be executed with.

The anti-theft ink may not be able to be read and the serial number cannot be recorded because the ink adheres to the serial number part depending on how the ink permeates the banknote. The anti-theft ink ejection method varies from manufacturer to manufacturer, such as ATM banknote cartridges and safes, and the ejection position is different. If the ink is soaked in the longitudinal direction from the center of the longitudinal direction, It is characterized by a case where a large amount of ink penetrates the short side after being ejected from the direction end.

If the serial number cannot be read, it will be easier to track where the banknote has been stolen from the penetration of the anti-theft ink if there is an image of the banknotes traded, but the image resolution performance is such that the serial number of small letters can be read. As the value increases, the amount of information per sheet becomes enormous. On the other hand, the processing time required for transactions is also increasing. Accordingly, it is not realistic to store a single banknote image that has been traded and read as it is in the storage device every time it is conveyed.

As described above, in this embodiment, when the serial number cannot be read, instead of the serial number, only the border line of the ink between the banknote frame and the portion of the banknote frame where the ink has been infiltrated or not. By recording IDs indicating pre-registered estimated manufacturers and devices that are likely to permeate in the pattern that most closely matches the small image shown, it is possible to be stolen from where the ink is attached. It becomes possible to give candidates indicating whether or not the banknote has a characteristic, and it is possible to easily identify the theft source. Therefore, it is an effective means for detecting a stolen banknote and quickly identifying when the deposited banknote with theft-proof ink is deposited and where it is stolen.
