Here, the subscriber information contains information indicating the policy of the subscriber for using the services. Here, the policy contains the conditions for the subscriber to use the services, such as the consent of protecting the copyright or the refusal of address presentation. The provider information contains information indicating the conditions for providing the services.

Description

Description: Contract Agency Method and Apparatus Therefor

The present invention relates to information processing for electronic contract procedures. An example of this information processing is a contract processing performed between a service provider terminal connected to a computer network or the like and a subscriber terminal. The present invention also relates to a contract proxy device for proxying between a service provider terminal device and a subscriber terminal device. Background art

With the development of the information society in recent years, electronic data is increasingly used as a means of transmitting various types of information instead of traditional printed matter. Also, electronic data itself may be exchanged as valuable data. For example, settlement in electronic commerce and stock certificates have already been widely converted into electronic data and used. Japanese Patent Application Laid-Open No. H10-1989872 is a conventional technique relating to information processing of a contract. This is to connect to the service provider for each contract and perform the contract procedure if you want to contract with multiple service providers using the network. In this conventional technology, in order to execute a contract procedure, a means for collecting and storing contract terms presented by a service provider and a means for performing a contract application process to a service provider on behalf of a subscriber are provided by: Make a contract with multiple services in one application procedure. Disclosure of the invention

However, in the above-mentioned conventional technology, it is possible to obtain contract terms for a plurality of services and apply for a contract with a single connection, but a subscriber needs to at least read and confirm the plurality of contract terms. In other words, it takes time for the subscriber himself to check the individual contract clauses, even for the items that he / she has licensed.

If a new service is added, it is necessary to process the contract separately.

In order to solve the above problems, the present invention has the following configuration. When the subscriber information on the service usage of the subscriber who receives the service under the contract and the provider information on the service provision of the provider who provides the service under the contract match, the information processing for the contract is executed. is there. Here, the subscriber information includes information indicating the policy of the subscriber when using the service. Here, the policy includes conditions under which the subscriber uses the service, for example, when he / she agrees to protect the copyright and when he / she refuses to provide his / her address. In addition, the provider information includes information indicating conditions for providing the service.

Note that the contract described in the present invention means that the provider and the subscriber agree on the conditions for using the provided service. BRIEF DESCRIPTION OF THE FIGURES

Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of an apparatus for implementing a contract acting method according to the present invention.

As shown in FIG. 1, the system according to the present embodiment includes a subscriber terminal device 20 operated by a subscriber who applies for a contract for using a service, and a service providing contract provided by a provider for providing a service. Terminal device 30, which is used to process the information, contract agent device 10, which acts as a contract between the subscriber terminal device 20, and the provider terminal device 30, and is connected to these devices. It is configured by Network 1. The subscriber terminal device 20, the provider terminal device 30, and the contract agent device 10 are portable terminals, personal computers, and workstations. —Chillon. Network 1 may be a LAN or telephone line. In order for the subscriber to use the service provided by the provider, it is necessary to access the provider terminal device 30 and make a contract in advance. The subscriber receives the right to use the service only after the contract has expired. According to the present invention, the contract proxy device 10 makes a contract with the provider on behalf of the subscriber, and provides the subscriber registered in the contract proxy device 10 with the secondary right to use the service. It is.

The contract agent device 10 includes an external storage device 11 such as a hard disk, a main storage device 12 such as a memory, an input device 13 such as a mouse and a keyboard, an output device 14 such as a display, and a modem. A communication device 15 and a central processing unit 16 such as a CPU are connected by a bus. The external storage device 11 stores a use determination program 101 and communication programs 100 such as a Web browser, a Web server, a mailer, and a mail server. At the start of the operation of this embodiment, these programs are loaded into the main storage device 12. The external storage device 11 stores a subscriber contract template file 200, a subscriber information file 201, a provider contract template file 300, and a provider information file 310.

The subscriber terminal device 20 includes an external storage device 21, a main storage device 22, an input device 23, an output device 24, a communication device 25, and a central processing unit 26 connected by a bus. Take the configuration to connect. The external storage device 21 stores a communication program 100. At the start of the operation of the present embodiment, the communication program 100 is loaded into the main storage device 22. The external storage device 21 stores a subscriber information file 201 and a use information file 302.

In the provider terminal device 30, an external storage device 31, a main storage device 32, an input device 33, an output device 34, a communication device 35, and a central processing unit 36 are connected by a bus. Take the configuration to connect. The main storage device 32 has a communication program 1 0 0 is stored. At the start of the operation of the present embodiment, the communication program 100 is loaded into the main storage device 32. The external storage device 31 stores a provider information file 301.

FIG. 2 is a block diagram showing processing of a program for executing the contract acting method according to the present invention. The contract proxy device 10 collects the subscriber information file 201 and the provider information file 301 from the subscriber terminal device 20 and the provider terminal device 30, respectively, and includes the contract policy data contained therein. If the two are compared with the contract clause data 302 and both of the requirements are satisfied, the use information data 303 is transmitted to the destination indicated by the access point directory 203.

The usage judging program 101 compares the subscriber information file 201 with the provider information file 301 to judge whether or not both requirements are satisfied.

The communication program 100 has a function of transmitting information to another device via a network and receiving information from another device. To send information, enter the information you want to send and the destination (access point) in the communication program 100.

The subscriber information file 201 has a contract policy data 202 and an access point data 203. The provider information file 301 has contract clause data—evening 302 and usage information data 303.

The subscriber contract template file 200 and the provider contract template file 300 indicate the formats for creating the subscriber information file 201 and the provider information file 301, respectively. is there.

In the present invention, the type of service processed by the contract proxy device 10 may be plural (for example, watching videos, estimating insurance, distributing electronic news, etc.). The contract proxy device 10 has a subscriber contract table for each type of service. A template file 200 and a provider contract template file 300 are prepared. The subscriber and the provider register the subscriber information file 201 and the provider information file 301 for each type of service.

FIG. 3 is a diagram showing an example of the contract policy data 202. The contract policy 202 contains information to identify the subscriber (eg, the subscriber ID) and the subscriber's policy on the contract matters. The subscriber's policy is to use the services provided by the provider, for example, as shown in Fig. 3, when they agree to protect the copyright, or refuse to provide their address. That's what happened. In the example shown in Fig. 3, the policy is either "permitted" or "denied". However, even if there is no entry due to the inability to select or if there is a weighting such as "permitted rather". good. The subscriber's policy is used as a means to determine whether or not the terms and conditions provided by the provider are met. In other words, if the subscriber's policy satisfies the terms and conditions, the subscriber gets the right to use the services provided by the provider. For example, if a subscriber's policy satisfies the terms and conditions for multiple services, the subscriber will be entitled to multiple services. In order for a subscriber to narrow down from a large number of services to services suitable for himself, conditions for narrowing down to a subscriber's policy may be included. The conditions for narrowing down are, for example, “the charge is 3 yen / min or less” or “5 services in descending order of the frequency of use”. Contract policy data 202 is created by the subscriber.

FIG. 4 is a diagram showing an example of the access point data 203. The access point data 203 has information for identifying a subscriber (for example, a subscriber ID) and information of a destination to which information necessary for using the service is transmitted. The destination information is, for example, the destination address and the E-Mai 1 address as shown in FIG. Access point information data 2 0 3 Is created by the subscriber.

FIG. 5 is a diagram showing an example of the subscriber contract template file 200. As shown in Fig. 5, the subscriber contract template file 200 is used to create a genre representing the type of service, and access point data 203 and contract policy data 202. Have the necessary items and options.

For example, FIG. 5 shows a subscriber contract template file 200 for two kinds of services such as watching a movie and car insurance. These are stored in the external storage device 11 of the contract agent device 10.

The subscriber first obtains the subscriber contract template file 2000 from the contract proxy device 10. The subscriber creates a subscriber information file 201 in accordance with the format indicated by the subscriber contract template file 200.

FIG. 6 is a diagram showing an example of the contract clause data 302. The contract clause date 302 contains information for identifying the provider (for example, provider ID), information for identifying the service (for example, service ID), and the provider's conditions for the contract items. Having. The terms and conditions of the provider include, for example, as shown in Fig. 6, that consent is required to protect the copyright in providing the service to the subscriber, and it is not necessary to provide an address. In the example of Fig. 6, the condition is either "necessary" or "unnecessary", but there is no entry due to the inability to select or weighting such as "necessary". There may be. The contract clause data 302 is created by the provider _c . FIG. 7 is a diagram showing an example of the use information data 303. Usage information data 303 includes information for identifying a provider (for example, provider ID), information for identifying a service (for example, service ID), and information (for example, a service necessary for using a service). For example, it has access points, user IDs, passwords, etc. and service descriptions (eg, provider names, service names, usage fees, etc.). The use information data 303 is created by the provider. FIG. 8 is a diagram showing an example of the provider contract template file 300. As shown in Fig. 8, the provider contract template file 300 is required to create a genre that represents the type of service, contract clause data 302, and usage information data 303. Items and options.

For example, FIG. 8 shows a provider contract template file 300 for two types of services, such as video appreciation and car insurance. These are stored in the external storage device 11 of the contract proxy device 10.

The provider first obtains the provider contract template file 300 from the contract proxy device 10. The provider creates a provider information file 301 according to the format indicated by the provider contract template file 300.

Next, an example of the operation of the present embodiment will be specifically described. Here, a method in which a subscriber makes a contract with an arbitrary provider by using the contract proxy device 10 will be described. The subscriber uses a personal computer which is the subscriber terminal device 20. A Web browser and a mailer are mounted on the personal computer as the communication program 100.

First, the subscriber accesses the contract proxy device 10 using the Web browser.

The homepage provided by the contract proxy device 100 provides a download service for the subscriber contract template file 200 and the provider contract template file 300. Each template file is in text format.

Next, the subscriber selects and downloads the genre “movie appreciation” from the two types of subscriber contract template files 200 as shown in FIG.

Next, the subscriber edits the blank of the subscriber contract template file 200 on the personal computer. For example, the name and E—Mai 1 address In the fields, write "Ryo Ozenji" and "ryo @mai 1.com" as shown in Fig. 4. Write a value as shown in Fig. 3 in the policy column. The edited template file is called a subscriber information file 201. Next, the subscriber attaches the subscriber information file 201 to the e-mail using a mailer, and transmits it to the contract proxy device 10.

FIG. 9 is a flowchart for explaining the processing of the usage judging program 101 when the contract proxy device 10 receives the subscriber information file 201 from the subscriber.

First, the received subscriber information file 201 is stored in the external storage device 11. At this time, a subscriber ID is set in the subscriber information file 201 in order to identify the subscriber (step 201).

Next, the contract terms and conditions 302 in the provider information file 301 are loaded from the external storage device 111 (step 2002).

The loaded contract terms and conditions 302 are compared with the contract policy data 202 in the subscriber information file 201 (step 203).

If the contract policy data 202 meets the conditions of the contract clause data 302, the service ID of the contract clause data 302 is acquired. If the conditions are not satisfied, the use determination program 101 ends. For example, if the contract policy data 202 and the contract clause data 302 are as shown in FIGS. 3 and 6, the service ID is obtained because the conditions are satisfied. For example, in FIG. 6, in the case of contract clause data 302 that the necessity for presentation of the name of the contract matter is “essential”, the contract policy data 202 shown in FIG. 3 does not satisfy the condition. Therefore, the usage judgment program 101 ends. If there is more than one contract clause data 302, compare all contract clauses 302 with the contract policy 202 in the received subscriber information file 201. A contract clause that satisfies the conditions Get ID. Here, it is assumed that the contract policy data 202 satisfies the conditions of two contract provisions in addition to the contract provision data 302 shown in FIG. In that case, the service ID "9898" and two other services are acquired (Step 2004).

Next, the usage information data 303 and the other two usage information data as shown in FIG. 7 corresponding to the three acquired service IDs are imported from the external storage device 11 (step 2005).

The information describing the service included in each of the three usage information data 303 loaded is presented to the subscriber, and confirmation is made as to whether or not to sign a contract for these services. If the subscriber cannot confirm, the use determination program 101 ends without proceeding to step 2007 (step 2006).

The loaded three usage information data 303 is attached to the e-mail, and the E—Ma i 1 address indicated by the access point data 203 in the subscriber information file 201 (“ryo @ ma i 1.com) To; 1 £ shin (Sup 2007).

The subscriber receives three pieces of usage information data 303. For example, in order to use the service corresponding to the usage information data 303 as shown in FIG. 7, the user accesses “www.movie, com” as described in the usage information data 303, and Enter your ID and password. The same is true for the other two services.

Fig. 10 shows the process of comparing the contract policy data 202 and the contract clause data 302 in the processing of the usage judgment program 101 to determine whether both meet the conditions (steps shown in Fig. 9). 2003 and step 2004). As an example of the condition determination routine, a process of comparing the contract policy data 202 shown in FIG. 3 with the contract clause data 302 shown in FIG. 6 will be described. First, contract policy data 202 and contract clause data 302 are acquired (step 1001).

Next, the number of items of the contract items is obtained. In this example, there are three consent restrictions and four presentation restrictions, for a total of seven contractual items (step 1002). The following processing is repeated as many times as the number of contract items (in this example, seven times). When the repetition is completed, the process proceeds to step 1007 (step 1003, step 1.004).

In the loop, the policy and condition values for the contract provisions of the contract policy data 202 and contract provision data 302 are checked one by one in order. First, the conditions of the contract clause data 302 are examined. If the condition is "required", proceed to the next step; if it is "unnecessary", proceed to step 1003. In FIG. 6, since the value of the condition for the contract item "agreement of copyright protection" is "essential", the process proceeds to the next step 106 (step 1005).

Next, the policy of the contract policy data 202 is examined for the contract matter ("agreement of copyright protection") examined in step 105. If the policy is "permitted", the procedure returns to step 103 for this item ("agreement on copyright protection"), meaning that the conditions have been met, and examines the next item. If the policy is "deny", the condition determination routine ends in the meaning that the condition was not satisfied. In FIG. 3, since the value of the policy for the contract item "Agreement of copyright protection" is "permitted", the process returns to step 1003 (step 1006).

Next, steps 1004, 105, and 106 are repeated in order, such as comparing the values for the contract item “agreement to prohibit unauthorized use”. When the policy and conditions have been compared for all items, the subscriber ID ("1 2 3 4") and the service ID ("9") of the contract policy data 202 and contract provision data 302 are completed. 8 9 8 ") is output (Step 1 0 0 7).

In this flowchart, the subscriber ID and the service ID are not output unless the policy of the contract policy data 202 fully satisfies the conditions of the contract clause data 302. Here, in order to provide flexibility, the ratio of the subscriber's policy satisfying the condition presented by the provider may be calculated as an evaluation value and output together with the subscriber ID and the service ID. For example, if the policy satisfies 90% of certain conditions, the evaluation value is 90%.

By using the above method and apparatus, a subscriber can use a plurality of services by registering with the contract proxy apparatus 10 once. Also, by registering the number and quality of services to be used in the contract policy, it becomes easier for subscribers to find the services they want.

Next, the operation of the second embodiment will be specifically described. Here, a method of making a contract with an arbitrary subscriber from the provider side using the contract proxy device 10 will be described. The provider uses a personal computer which is the provider terminal device 30. A Web browser and a mailer are implemented as the communication program 100 in the personal computer.

First, the provider accesses the contract proxy device 10 using the Web browser.

First, the provider selects and downloads the genre of "video appreciation" from the two types of provider contract template files 300 shown in Fig. 8 in the homepage provided by the contract proxy device 10. I do.

Next, the provider edits the blank of the provider contract template file 300 on a personal computer. For example, write values as shown in Fig. 7 in the fields such as provider name and service name. Write the values shown in Fig. 6 in the condition column. The template file that has been edited is called the provider information file 301. Next, the provider attaches the provider information file 301 to the e-mail using a mailer, and transmits it to the contract proxy device 10.

FIG. 11 is a flowchart for explaining the processing of the usage judging program 101 when the contract proxy device 10 receives the provider information file 301 from the provider.

First, the received provider information file 301 is stored in the external storage device 11. At this time, a provider ID and a service ID are set in the provider information file 301 in order to identify the provider and the service (step 3001). Next, the contract policy data 202 in the subscriber information file 201 is loaded from the external storage device 11 (step 3002).

The loaded contract policy data 202 is compared with the contract clause data 302 in the provider information file 301 (step 3003).

If the contract policy data 202 satisfies the conditions of the contract clause data 302, the subscriber ID of the contract policy data 202 is acquired. If the conditions are not satisfied, the use judgment program 101 ends. For example, if the contract policy data 202 and the contract clause data 302 are those shown in FIGS. 3 and 6, the conditions are satisfied and the subscriber ID ("1 2 3 4 "). If there is more than one contract policy data 202, compare all contract policy data 202 with the contract clause data 302 in the received provider information file 301 and satisfy the conditions. The subscriber ID is acquired for the contract policy data 202 (step 304).

Note that the detailed description of the process of comparing the contract policy data 202 with the contract clause data 302 to determine whether both satisfy the conditions (steps 3003 and 304) has already been described in Section 3. Since it has been described with reference to FIG. 10, it is omitted here.

Next, the access voice corresponding to the obtained subscriber ID as shown in Fig. 4 The client data 203 is loaded from the external storage device 11 (step 3005).

First, the information describing the service included in the usage information data 303 received is presented to the corresponding subscriber, and confirmation is made as to whether or not to sign a contract for this service. For the subscriber whose confirmation cannot be obtained, the use judgment program 101 ends without proceeding to step 3007 (step 3006).

To the E—Ma i 1 address (“r yo @ ma i 1.com”) indicated by the loaded access point data 203, use information in the provider information file 301 received first. The data 303 is transmitted (step 3007). By using the above method and device, the subscriber can automatically use the service provided by the provider without registering for new registration or change of the service.

FIG. 12 is a block diagram showing a third example of processing of a program for executing the contract acting method of the present invention. Note that the components having the same functions as those in FIG.

The provider terminal devices 30, 30 ', 30 "provide unique services 103, 103', 103", respectively. The service integration device 40 has a service integration program 102. The service integration program 102 acquires a plurality of services from the provider terminal device 30 and integrates them to provide one high-value-added service to the subscriber terminal device 20. In the following, integrated services with high added value are simply called integrated services. The function of the contract agent device 10 and the function of the service integration device 40 may be combined into one device, and the contract agent process and the service integration process may be performed together.

FIG. 13 is a diagram showing an example of a group of contract policy data 202 and a group of contract clause data 302 registered for this integrated service. The two contract ports on the left Rishi represents the contract policy for two subscribers. The three contract terms on the right represent the contract terms for three providers.

FIG. 14 is a flowchart illustrating a contract process when a subscriber uses an integrated service.

First, an intermediary managing the service integration device 40 creates a subscriber contract template file 200 for a subscriber who uses the integrated service, and registers it in the contract proxy device 10. Also, the mediator creates a provider contract template file 300 for the provider providing each service to be integrated, and stores it in the contract agency device 10. At this time, an address that can be received by the service integration device 40 is set in advance in the E-Mai 1 address column corresponding to the access point in the subscriber contract template file 200 (step 4001).

The provider creates a provider information file 301 from the provider contract template file 300 and registers it in the contract proxy device 10 (step 4002). The subscriber creates a subscriber information file 201 from the subscriber contract template file 200 and registers it in the contract proxy device 10 (step 4003).

Next, the usage judgment program 101 is started, and the contract policy data 200 included in the subscriber contract template file 200 and the contract clause data 3 included in the provider contract template file 300 are stored. 0 Compare 2 In Fig. 13, the contract policy with a subscriber ID of 1001 satisfies the conditions indicated by the contract clauses with service IDs of 981 and 9802, but with a service ID of 9 The terms of the contract, which is 803, are not met. In Fig. 13, the contract policy with a subscriber ID of 1002 satisfies the conditions indicated in all the contract terms. (Step 4004)

The usage judging program 101 obtains, for the subscriber with the subscriber ID 1001, the use information of the services with the service IDs 9801 and 9802. Get. Since the destination indicated by the access point data 203 with the subscriber ID 1001 is the service integration device 40, the two pieces of usage information are sent to the service integration device 40 (step 4005). .

The service integration program 102 acquires two pieces of usage information, and integrates using services whose service IDs are 9801 and 9802. Then, the service integration program 102 provides the integrated service to the subscriber whose subscriber ID is 1001. Similarly, the usage judgment program 101 provides three services with service IDs 980, 982, and 9803 to a subscriber with a subscriber ID of 1002. Provide integrated services. (Step 400)

By using the above method and device, it is possible to provide integrated services suitable for the subscriber's contract policy by registering the subscriber's contract policy once in the contract proxy device 10 .

As described above, in the embodiment of the present invention, the contract proxy device stores the subscriber's contract policy and the provider's contract clause for service use, and stores the contract policy and the contract clause. By having and operating a usage decision program to determine whether a service use contract is concluded from the date and time, the subscriber only needs to register the contract policy data once in the contract proxy device, Services become available.

In the embodiment of the present invention, by registering the number and quality of services used during a contract policy, it becomes easy for a subscriber to find a desired service.

Further, in the embodiment of the present invention, the subscriber can automatically use the service provided by the provider without newly contracting for the new registration or change of the service provided by the provider. These reduce contract processing. Further, in the embodiment of the present invention, the service use information is integrated with the service. By sending it to the program, it will be possible to provide integrated services suitable for the subscriber's contract policy. Industrial applicability

According to the present invention, it is possible to more easily execute information processing for making an electronic contract.
