[Overview of securities management system S]
FIG. 1 is a diagram showing an outline of a securities management system S according to an embodiment. The securities management system S is a system for managing securities, and has a securities management device 1 and a blockchain 2. Securities are securities that indicate rights with property value, such as stock certificates, bonds, beneficiary certificates of investment trusts, and anonymous union contracts. In this embodiment, for the sake of simplicity, the issuer of securities such as a corporate entity issues securities such as one company, and the securities management system S manages the securities such as one company. I will explain it as something to do.

The securities management device 1 is a computer that manages rights information indicating the rights relationship of securities. The securities management device 1 stores rights information indicating the rights relationship of securities. Further, the securities management device 1 stores the user ID as the user identification information for identifying the user of the securities management device 1 as the owner of the securities in the blockchain 2 in association with the token information indicating the securities. Let me. The token information is information used not only to indicate securities but also to refer to the rights information of securities owned by the user.

The securities management device 1 accepts an application for transfer of securities from a first user terminal 3 used by a transfer applicant who is a user who wishes to transfer securities ((1) in FIG. 1). The securities management device 1 accepts an application for transfer of securities from a second user terminal 4 used by a transfer applicant who is a user who wishes to transfer securities ((2) in FIG. 1).

The securities management device 1 matches the transfer applicant and the transfer applicant ((3) in FIG. 1), and notifies the matched transfer applicant and the transfer applicant of the matching result indicating that they have been matched. ((4) in FIG. 1).

When the securities management device 1 accepts the transfer agreement from the transfer applicant ((5-1) in FIG. 1) and receives the transfer agreement from the transfer applicant ((5-2) in FIG. 1), the transfer is made. Generates rights information indicating the rights relationship after the transfer of the securities subject to ((6) in FIG. 1). The securities management device 1 stores the generated rights information in a storage medium ((7) in FIG. 1).

Further, when the securities management device 1 accepts the transfer and transfer agreement, the user ID associated with the token information corresponding to the securities to be transferred is changed to the user ID of the transferee (in FIG. 1). (8)). As a result, the transferee becomes the holder of the securities and can refer to the rights information of the securities owned by himself / herself by using the token information corresponding to his / her user ID.

As described above, since the securities management device 1 can automatically perform the procedure for transferring the securities shown in FIG. 1, it is possible to easily transfer the rights of the securities.

[Configuration of securities management device 1]
Subsequently, the configuration of the securities management device 1 will be described. FIG. 2 is a diagram showing a configuration of a securities management device 1 according to an embodiment. As shown in FIG. 2, the securities management device 1 includes a communication unit 11, a storage unit 12, and a control unit 13.

The communication unit 11 is, for example, a communication interface for communicating with a user terminal used by the user of the securities management device 1 and a group of servers constituting the blockchain.

The storage unit 12 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The storage unit 12 stores a program executed by the control unit 13. For example, the storage unit 12 stores a program that causes the securities management device 1 to function as a storage control unit 131, a rights information providing unit 132, a matching unit 133, an agreement reception unit 134, an owner change unit 135, and a monitoring unit 136. is doing.

Further, the storage unit 12 stores user information in which the user who uses the securities management device 1, that is, the user ID for identifying the transfer applicant and the transfer applicant of the securities, and the personal information of the user are associated with each other.

The control unit 13 is, for example, a CPU (Central Processing Unit). By executing the program stored in the storage unit 12, the control unit 13 serves as a storage control unit 131, a right information providing unit 132, a matching unit 133, an agreement reception unit 134, an owner change unit 135, and a monitoring unit 136. Function.

The storage control unit 131 corresponds to each of the plurality of issued securities, and stores the right information indicating the rights relationship of the securities in the storage unit 12. The storage control unit 131 stores the right information corresponding to each of the issued plurality of securities in the storage unit 12 by the operation of the securities issuer. The rights information is, for example, list information such as a shareholder list, a corporate bond register, a member list, a contract related to investment, a contract related to the transfer of securities, and history information of these information. The storage control unit 131 has decided to store all of the right information in the storage unit 12, but the present invention is not limited to this, and for example, the list information may be stored in the blockchain. The securities management device 1 can prevent falsification of the list information by storing the list information in the blockchain.

The storage control unit 131 stores the user ID that identifies the user who owns the securities in the blockchain 2 in association with the token information that indicates the securities and is used when the user refers to the rights information. The storage control unit 131 stores the user ID of the user who owns the securities and the token information in the blockchain 2 in association with each other, for example, by the operation of the securities issuer.

First, the storage control unit 131 receives, for each of the plurality of securities, a white list, which is a list of the owner of the securities and the users who can transfer the securities, from the issuer of the securities. A whitelist is set for each of multiple securities.

The storage control unit 131 stores the token information including the whitelist corresponding to the securities owned by the user in the storage area corresponding to the user in the blockchain 2. Specifically, the blockchain 2 is assigned a wallet as a storage area corresponding to each of the plurality of users.

FIG. 3 is a diagram showing the relationship between the blockchain 2, the wallet, and the token information. The storage control unit 131 stores the token information corresponding to the user in the wallet associated with the user ID of the user who owns the securities. The wallet stores a plurality of token information corresponding to the quantity of securities owned by the user and a private key used when transferring the token information. The token information stores a smart contract, which is a transfer application program that executes processing related to securities transfer procedures and generates rights information when securities are transferred. The smart contract contains an authentication key used to refer to the rights information corresponding to the token information stored in the smart contract, and a whitelist.

The storage control unit 131 may update the whitelist by accepting editing of the whitelist from the issuer of securities after the token information is stored in the wallet. For example, the storage control unit 131 may update all whitelists at once by accepting additions and deletions of users to the whitelists corresponding to each of all token information. By doing so, the securities management device 1 can update the whitelist according to the wishes of the issuer of securities.

The rights information providing unit 132 receives rights information corresponding to securities indicated by token information associated with the user from a terminal used by the user (for example, a user terminal including the first user terminal 3 and the second user terminal 4). When the reference request is received, the rights information corresponding to the securities stored in the storage unit 12 is transmitted to the terminal. When the rights information providing unit 132 receives a reference request for the rights information corresponding to the securities indicated by the token information from the terminal used by the user, the authentication key included in the smart contract stored in the token information and the authentication key Authentication is performed based on the transaction information indicating that the token information is stored in the wallet, and if the authentication is successful, the right information is transmitted to the terminal.

Specifically, first, the rights information providing unit 132 is included in the smart contract stored in the token information stored in the wallet of the user in response to the operation of the terminal of the user who owns the securities. The authentication key to be obtained and the transaction information corresponding to the token information are acquired. The right information providing unit 132 determines whether or not the user viewing the right information is a legitimate user based on whether or not the authentication key and the transaction information correspond to each other.

When the right information providing unit 132 determines that the user is a legitimate user and succeeds in authentication, the rights information providing unit 132 transmits the rights information corresponding to the user stored in the storage unit 12 to the user's terminal. Provide rights information to the user.

The matching unit 133 matches a transfer applicant who wishes to transfer securities with a transfer applicant who wishes to transfer securities. For example, the matching unit 133 receives a transfer request including a user ID and the desired number of securities to be transferred from the first user terminal 3 used by each of the one or more transfer applicants, and also receives one or more transfer applicants. The transfer request including the user ID and the desired number of securities to be transferred is received from the second user terminal 4 used by each of the above.

When the matching unit 133 receives one or more transfer requests and one or more transfer requests, the matching unit 133 performs matching between the transfer applicant and the transfer applicant. For example, the matching unit 133 performs matching between the transfer applicant and the transfer applicant at predetermined time intervals. The matching unit 133 allocates the transfer applicants having the same number of transfer applicants as the transfer applicants to the transfer applicants who transfer securities from the transfer applicants. Here, when assigning the transfer applicant, the matching unit 133 refers to the white list included in the token information corresponding to the securities owned by the transfer applicant, and the transfer applicant included in the white list. And match with the transfer applicant. By doing so, the issuer of the securities can transfer the securities only to those who wish to transfer the securities.

If there is no transfer applicant with a transfer request number that matches the transfer request number, the matching unit 133 assigns a plurality of transfer applicants to one transfer requester to obtain a plurality of transfer request numbers. You may match the total of the above with the desired number of transfers. In addition, if there is no transfer applicant with a transfer request number that matches the transfer request number, the matching unit 133 assigns a plurality of transfer applicants to one transfer applicant to obtain a plurality of transfer request numbers. You may match the total of the above with the desired number of transfers.

The agreement reception unit 134 accepts an agreement on the transfer of securities from the transfer applicant matched by the matching unit 133, and also receives an agreement on the transfer of securities from the transfer applicant. For example, the agreement reception unit 134 matches the first user terminal 3 used by the transfer applicant to indicate that the transfer applicant has been assigned to the transfer applicant and the quantity of securities to be transferred to the transfer applicant. Notify the result information and accept the agreement to transfer the securities from the first user terminal 3. In addition, the agreement reception unit 134 matches the second user terminal 4 used by the transfer applicant to indicate that the transfer applicant has been assigned to the transfer applicant and the quantity of securities to be transferred from the transfer applicant. Notify the result information and accept the agreement on the transfer of securities from the second user terminal 4.

When the agreement reception unit 134 accepts the transfer and transfer agreement, the owner change unit 135 generates right information indicating the rights relationship after the transfer of the securities to be transferred and stores it in the storage unit 12. Further, the owner change unit 135 changes the user ID associated with the token information corresponding to the securities to be transferred from the user ID of the transfer applicant to the user ID of the transfer applicant, and the transfer applicant's user. The ID and the token information corresponding to the securities are associated and stored in the blockchain 2. When the agreement reception unit 134 accepts the transfer and transfer agreement, the owner change unit 135 transfers the token information and generates the right information by executing the smart contract.

Specifically, first, the owner change unit 135 wishes to transfer when the agreement reception unit 134 accepts the transfer and transfer agreement, the contract with the transfer of securities is concluded, and the payment procedure is completed. Execute the smart contract stored in the wallet corresponding to the person. For example, in the smart contract, the user ID of the transferee, the user ID of the transferee, and the transfer quantity are input.

The smart contract generates the rights information of the securities corresponding to the token information newly stored in the wallet corresponding to the transferee. The smart contract refers to the user information stored in the storage unit 12, and acquires the personal information associated with each of the user ID of the transferee and the user ID of the transferee. The smart contract updates the list information included in the rights information based on the acquired personal information and the input transfer quantity, and newly generates a contract or the like.

Subsequently, the smart contract newly generates token information corresponding to the securities to be transferred, stores it in the wallet corresponding to the transferee, and stores the token information corresponding to the securities to be transferred. , The token information is transferred to the wallet corresponding to the transfer applicant by deleting it from the wallet corresponding to the transfer applicant. In this way, the owner change unit 135 changes the user ID associated with the token information from the user ID of the transfer applicant to the user ID of the transfer applicant by executing the smart contract, and the transfer applicant changes the user ID. The user ID and the token information corresponding to the securities can be associated and stored in the blockchain 2. As a result, the transferee can immediately refer to the rights information when the securities are transferred.

Further, the smart contract stores the transfer history information indicating that the owner of the securities to be transferred has transferred from the transfer applicant to the transfer applicant in the blockchain 2. Since it is difficult to falsify the information stored in the blockchain 2, it is also difficult to falsify the movement history information. Therefore, by storing the transfer history information in the blockchain 2, it is possible to suppress the unauthorized transfer of securities.

In the embodiment, the transfer history information stored in the blockchain 2 can be referred only to the issuer of the securities, but is not limited to this. For example, see only the transfer history, which indicates that the current owner of the security and the past owner of the security have transferred the security to itself, and the transfer history, which indicates that the security has been transferred from itself. It may be possible. Further, the owner change unit 135 transfers the token information to the smart contract by executing the smart contract, but the present invention is not limited to this. The owner change unit 135 may transfer the token information and then execute the smart contract included in the transferred token information to cause the smart contract to generate the rights information of the securities.

The monitoring unit 136 monitors whether or not invalid data is input in the blockchain 2. The storage unit 12 stores a classification program that outputs information indicating whether the input data is normally input data or illegally input data in response to data input. The classification program is a program generated by learning in advance based on positive data normally input in the past and negative data illegally input in the past in the blockchain 2.

The positive data normally input is, for example, an access log to the securities management device 1 of the first user terminal 3 and the second user terminal 4 when the securities are normally transferred. Negative data entered illegally is, for example, securities of the first user terminal 3 and the second user terminal 4 when the transfer of securities is not performed normally or when the transfer of securities is canceled. This is an access log for the management device 1.

The monitoring unit 136 classifies the information regarding the access of the first user terminal 3 and the second user terminal 4 into the classification program according to the access of the securities management device 1 from the first user terminal 3 and the second user terminal 4. Based on the information that is input and output from the classification program, it is monitored whether or not invalid data is input in the blockchain 2. When the monitoring unit 136 detects that invalid data has been input, it notifies, for example, that the invalid data has been input to the terminal used by the issuer of the securities.

[Processing flow in securities management device 1]
Subsequently, the flow of processing in the securities management device 1 will be described. FIG. 4 is a flowchart showing a flow of processing related to the transfer of securities executed by the securities management device 1 according to the embodiment.

First, the matching unit 133 accepts the transfer request from the first user terminal 3 used by the transfer applicant, and also receives the transfer request from the second user terminal 4 used by the transfer applicant (S1).
Subsequently, the matching unit 133 executes matching between the transfer applicant who has made the transfer request and the transfer applicant who has made the transfer request (S2).

Subsequently, the agreement reception unit 134 accepts the transfer agreement from the matched transfer applicant and also accepts the transfer agreement from the transfer applicant (S3).

Subsequently, when the agreement reception unit 134 accepts the transfer and transfer agreement, the owner change unit 135 transfers the token information corresponding to the securities to be transferred to the wallet corresponding to the transfer applicant (S4). ).

Subsequently, the owner change unit 135 executes the smart contract stored in the wallet corresponding to the transferee (S5). As a result, the right information corresponding to the transferred securities is generated and stored in the storage unit 12, and the key information corresponding to the transferee is stored in the transferred token information.

[Effect in the embodiment]
