Description

  The present invention relates to an information management system, an information management method, and an information management program for conducting a transaction using personal information of a user.

  Understanding trends in market needs is useful in marketing. Therefore, it is conceivable to use purchase information and service usage information associated with personal attributes for marketing.

  Therefore, a technique for utilizing personal information accumulated by a credit card company or the like and stored in a database has been studied (see, for example, Patent Document 1). In the technology described in Patent Document 1, a third party receives a request for personal information of a specific individual from a client and defines a policy related to the sale of the personal information. Also, personal information is validated by a third party. The third party may ask the client to pass the personal information requested by the client to the client, or request permission from the individual on condition of payment of compensation. If permitted, provide the requested personal information to the requester.

  In addition, a technology for centrally managing personal information is also being studied (see, for example, Patent Document 2). The technology described in Patent Document 2 uses a personal information bank for managing personal information, and a client side client and a service provider side client for inputting, searching, referring to personal information, and the like. By centrally managing personal information in the personal information bank, both the service provider side and the customer side can register, update, delete and inquire information, and it is possible to identify the customer using other information as a key I assume.

  Further, in recent years, the efficiency of identity verification procedure (KYC: Know Your Customer) in a financial institution has also been considered (for example, see Non-Patent Document 1). In this document, a platform is under consideration in which financial institutions can commonly use an identity verification procedure (KYC) using blockchain technology.

  In addition, information banks utilizing personal data are also being studied (see, for example, Non-Patent Document 2). In this document, personal data such as attribute information, hobbies and preferences, health information, etc. are deposited in the information bank, and depending on the content and amount of the deposited information, and the disclosing company that has accepted it, the block chain's distributed ledger Grant a managed intracompany virtual coin. The personal data using company provides information in accordance with the taste, taste and behavior pattern corresponding to each person based on the obtained data.

The basic registration process is described with reference to FIG. This process is executed when a user who desires a transaction using personal information performs user registration. A user desiring to trade personal information accesses the information management server 20 using the user terminal 10.

  First, the control unit 21 of the information management server 20 executes acquisition processing of basic information (step S1-1). Specifically, the user registration unit 211 of the control unit 21 outputs a basic information input screen to the display of the user terminal 10. The basic information input screen includes personal identification information for collating the user, personal authentication information, an account identifier, and a contact address input field in a public organization. Then, the user registration unit 211 acquires various types of information input on the basic information input screen.

  Next, the control unit 21 of the information management server 20 executes the person verification process (step S1-2). Specifically, the user registration unit 211 of the control unit 21 accesses the verification server 30, and performs user identification of the user using the user identification information and the user authentication information acquired from the user terminal 10. Then, when the user identity can be confirmed, the user registration unit 211 assigns a user ID, generates a registrant management record 220, and records the user ID, the contact address, and the account identifier in the basic record.

  Next, the control unit 21 of the information management server 20 executes a registration process of the user terminal (step S1-3). Specifically, the user registration unit 211 of the control unit 21 acquires the terminal ID from the user terminal 10 and records the terminal ID in the basic record of the registrant management record 220.

  Next, the control unit 21 of the information management server 20 executes a result notification process (step S1-4). Specifically, the user registration unit 211 of the control unit 21 notifies the user terminal 10 that the user registration has been performed.

(Information registration process)
Information registration processing will be described with reference to FIG. This process is performed when the user who has received the notification of user registration accesses the information management server 20 using the user terminal 10.

  First, the control unit 21 of the information management server 20 executes a user authentication process (step S2-1). Specifically, the access authentication unit 210 of the control unit 21 acquires a terminal ID from the accessed user terminal 10. Then, when the terminal ID is recorded in the basic record of the registrant management record 220, the access authentication unit 210 completes the user authentication. If the terminal ID is not recorded in the basic record of the registrant management record 220, the access authentication unit 210 rejects the access.

  Next, the control unit 21 of the information management server 20 executes a registration process of user information (step S2-2). Specifically, the user registration unit 211 of the control unit 21 outputs a registration information input screen on the display of the user terminal 10. The registration information input screen is provided with input fields recorded in the information item list for information items provided to the purchaser. Furthermore, the registration information input screen is provided with the service provider used by the user and an input field for the account of each service provider. In this case, the user inputs item values of available information items. Furthermore, the account of the service provider used by the user is entered. Then, the user registration unit 211 acquires various types of information input on the registration information input screen. Then, the user registration unit 211 records the item value of the acquired information item in the information management record. Further, the user registration unit 211 records the acquired account of the service provider in the provider record.

  Next, the control unit 21 of the information management server 20 executes a provision condition setting process (step S2-3). Specifically, the user registration unit 211 of the control unit 21 outputs the provision condition setting screen to the display of the user terminal 10. In the provision condition setting screen, for each information item for which an item value is input on the registration information input screen, an item value and a provision condition when providing the user's personal information to the purchase applicant are set. In the present embodiment, it is assumed that, as the provision condition, the type of business of the purchase requester and the sales price are set for each information item. Then, the user registration unit 211 records the item value and the provision condition in the information management record for the information item set on the provision condition setting screen. The item values of the information management record and the provision condition data area are left blank for information items not selected on the provision condition setting screen.

(Registration information confirmation processing)
The registration information confirmation process will be described with reference to FIG. This process is periodically executed in the information management server 20 in order to keep the personal information updated. This process is repeatedly performed for each registrant.

Here, the control unit 21 of the information management server 20 executes the following processing for each provider recorded in the provider record of the registrant management record 220.
First, the control unit 21 of the information management server 20 executes acquisition processing of service usage information (step S3-1). Specifically, the information management unit 212 of the control unit 21 accesses the service provider server 40 of the provider recorded in the registrant management record 220 of the check target user, and acquires the service usage information of the account of this user Do. Then, the information management unit 212 specifies personal information (item value) related to the information item recorded in the information management record, from the service usage information acquired from the service provider server 40.

  Next, the control unit 21 of the information management server 20 executes a process of collating the registration information (step S3-2). Specifically, the information management unit 212 of the control unit 21 compares the personal information (item value) newly identified from the service provider server 40 with the item value recorded in the registrant management record 220.

  Next, the control unit 21 of the information management server 20 executes determination processing as to whether or not there is a possibility of inconsistency (step S3-3). Specifically, the information management unit 212 of the control unit 21 is likely to be inconsistent if the newly identified personal information (item value) is different from the item value recorded in the registrant management record 220. It is determined that there is

  If it is determined that there is a possibility of inconsistency (in the case of “YES” in step S3-3), the control unit 21 of the information management server 20 executes a warning process (step S3-4). Specifically, the information management unit 212 of the control unit 21 records a warning flag in the situation data area for the information item of the user. On the other hand, when it is determined that there is no possibility of inconsistency (in the case of “NO” in step S3-3), the control unit 21 of the information management server 20 skips the alerting process (step S3-4).

  Next, the control unit 21 of the information management server 20 executes determination processing as to whether or not there is unregistered information (step S3-5). Specifically, the information management unit 212 of the control unit 21 specifies an information item in which the item value data area of the registrant management record 220 is blank. Then, the information management unit 212 confirms whether or not there is personal information (item value) corresponding to the blank information item in the information acquired from the service provider server 40. The personal information (item value) corresponding to the blank information item is acquired, and when it can be registered, it is determined that there is unregistered information.

  If it is determined that there is unregistered information (in the case of “YES” in step S3-5), the control unit 21 of the information management server 20 executes a registration proposal process (step S3-6). Specifically, the information management unit 212 of the control unit 21 records a proposal flag in the situation data area for this information item. On the other hand, when it is determined that there is no unregistered information (in the case of “NO” in step S3-5), the control unit 21 of the information management server 20 skips the registration proposal process (step S3-6).

Repeat for all providers recorded in the provider record of the registrant management record 220 of this user.
Then, the control unit 21 of the information management server 20 executes a message output process (step S3-7). Specifically, when the registrant management record 220 includes an information item in which a warning flag or a proposal flag is recorded, the information management unit 212 of the control unit 21 sends the contact information of the registrant management record 220. Send a message. This message includes confirmation of the content of the information item and a proposal for registering unregistered information.

In this case, the information registration process shown in FIG. 7 is performed again. Here, when the confirmation information of the user is acquired from the user terminal 10 for the information item in which the alerting flag is recorded, the user registration unit 211 deletes the alerting flag of the situation data area. Further, for the information item in which the unregistered flag is recorded, the user registration unit 211 acquires the provision condition from the user terminal 10 and updates the registrant management record 220. Also in this case, the proposal flag is deleted.
Then, the control unit 21 of the information management server 20 repeats the process for all the registrants.

(Trading process)
Transaction processing will be described with reference to FIG. This process is executed when a purchase request is obtained from a purchase requester of personal information.

  First, the control unit 21 of the information management server 20 executes a user authentication process (step S4-1). Specifically, the access authentication unit 210 of the control unit 21 outputs an authentication screen to the accessed purchaser terminal 50, and acquires the purchaser ID and authentication information input on the authentication screen. Then, when the purchaser ID and the authentication information are recorded in the purchaser information storage unit 24, the access authentication unit 210 completes the user authentication. If the purchaser ID and the authentication information are not recorded in the purchaser information storage unit 24, the access authentication unit 210 rejects the access.

  Next, the control unit 21 of the information management server 20 executes acquisition processing for purchase request (step S4-2). Specifically, the transaction management unit 213 of the control unit 21 acquires purchase request information from the purchaser terminal 50. The purchase request information includes information acquisition conditions. The information acquisition conditions include information items such as an information item of desired purchase conditions, a purchase number range, and a purchase upper limit unit price.

  Next, the control unit 21 of the information management server 20 executes a search process based on the information acquisition condition (step S4-3). Specifically, based on the information acquisition condition acquired from the purchaser terminal 50, the transaction management unit 213 of the control unit 21 searches the corresponding registrant management record 220. Here, the transaction management unit 213 extracts the registrant management record 220 in which the item value of the information item of the information acquisition condition is recorded. Next, the transaction management unit 213 narrows down the registrant management record 220 in which the type of business recorded in the purchaser management record 240 is recorded as a type of business that can be provided as a provision condition. Next, the transaction management unit 213 narrows down the registrant management records 220 in which the provided price recorded as the provision condition in each registrant management record 220 is equal to or less than the purchase upper limit unit price.

  Next, the control unit 21 of the information management server 20 executes determination processing as to whether personal information can be provided (step S4-4). Specifically, the transaction management unit 213 of the control unit 21 determines that provision is possible if the number of records of the narrowed registrant management records 220 is equal to or more than the lower limit number of the desired purchase number range.

  When the number of records is less than the lower limit number of the desired purchase number range and it is determined that the personal information can not be provided (in the case of "NO" in step S4-4), the control unit 21 of the information management server 20 Execute (step S4-5). Specifically, the transaction management unit 213 of the control unit 21 transmits a non-provable message to the purchaser terminal 50. This non-deliverable message includes a message indicating that the number of records in the desired purchase number range could not be extracted.

  On the other hand, when it is determined that personal information can be provided (in the case of “YES” in step S4-4), the control unit 21 of the information management server 20 executes purchase confirmation processing (step S4-6). Specifically, the transaction management unit 213 of the control unit 21 extracts the registrant management records 220 until the upper limit number of the desired purchase number range is reached in the order in which the offered price as the offered condition is cheap. Next, the transaction management unit 213 calculates the total price of the offer price of the registrant management record 220. Then, the transaction management unit 213 transmits a purchase confirmation message to the purchaser terminal 50. The purchase confirmation message includes the number of records of the extracted registrant management record 220 and data on the calculated total amount.

  Next, the control unit 21 of the information management server 20 executes a purchase application process (step S4-7). Specifically, the transaction management unit 213 of the control unit 21 acquires, from the purchaser terminal 50, a reply message corresponding to the purchase confirmation message.

  Next, the control unit 21 of the information management server 20 executes personal information extraction processing according to the information acquisition condition (step S4-8). Specifically, the transaction management unit 213 creates a personal information list including the information items and the item values of the extracted registrant management record 220. In this case, edit so that the registrant can not be identified.

  Next, the control unit 21 of the information management server 20 executes a process of providing personal information (step S4-9). Specifically, the transaction management unit 213 of the control unit 21 transmits the created personal information list to the purchaser terminal 50. In this case, the transaction management unit 213 assigns a transaction ID, generates a provision history management record 230 in which the provision date (current date) and the purchaser ID are recorded, and records the record 230 in the provision history storage unit 23. Further, the transaction management unit 213 records, in the provision history management record 230, data on the user ID of each user who provided the personal information, the information item, and the provision amount.

  Next, the control unit 21 of the information management server 20 executes a deposit process (step S4-10). Specifically, the transaction management unit 213 of the control unit 21 deducts the total offer price (offer fee) from the purchaser's account recorded in the purchaser information storage unit 24.

  Next, the control unit 21 of the information management server 20 executes a payment distribution process (step S4-11). Specifically, the transaction management unit 213 of the control unit 21 uses the registrant management record 220 of the registrant information storage unit 22 to identify the account identifier of the user who provided the personal information. Then, the transaction management unit 213 deposits (returns) an amount according to the provided price to the account of each user.
