[Overview of information processing system S]
FIG. 1 is a schematic diagram of an information processing system S according to this embodiment. The information processing system S includes a crypto-asset management system 1 , a settlement server 2 and a user terminal 3 . The information processing system S may include devices such as other servers and terminals.

The crypto-asset management system 1 is one or more computers for managing information about crypto-assets. A crypto asset is an electronic asset (currency) that can be used for payment, etc., and is different from a legal currency. A crypto-asset may be an electronic asset backed by legal currency, such as an electronic asset with a value and guarantee equivalent to that of legal currency. A crypto asset can be converted into a predetermined currency at a predetermined conversion ratio. A crypto asset is associated with a user who holds the crypto asset in, for example, a storage device, and is transferred from a user who is a customer to a user who is a store when used for payment.

A crypto-asset is an electronic asset managed by, for example, a blockchain. Crypto assets are not limited to blockchains, and may be electronic assets managed by a database or the like. Crypto assets are managed in units of assets, which are predetermined units used for settlement (for example, units in circulation). Hereinafter, the asset unit of crypto assets is called a coin, but other names may be used.

A crypto asset may be a regional digital currency available in a given region. For example, settlement using crypto assets, which are regional digital currencies, can be performed at stores within a predetermined area, and cannot be performed at stores outside the area. Also, settlement using crypto assets, which are regional digital currencies, may be executable only at predetermined stores (for example, registered stores) within a predetermined area.

A crypto asset may be a local digital currency available to a given user. For example, settlement using crypto assets, which is a regional digital currency, can be executed at a store within a predetermined area in response to a request from a predetermined user, Impractical in stores. In a predetermined area and a predetermined user, for example, it is determined by the bearer who bears the funds for issuing the crypto assets.

The crypto-asset management system 1 manages the crypto-asset owned by each user in the crypto-asset account associated with the user. The crypto-asset management system 1 transfers crypto-asset from one user's crypto-asset account to another user's crypto-asset account, for example, in response to a transfer request received from the settlement server 2 . The crypto-asset management system 1 can communicate with the payment server 2 and the user terminal 3 via a network.

The payment server 2 (information processing device) is a computer for making payments using crypto assets. For example, in response to receiving a payment request from the user terminal 3, the payment server 2 issues a transfer request to the crypto-asset management system 1 to transfer the crypto-asset corresponding to the amount to be settled from one user to another user. to send. The settlement server 2 can communicate with the crypto-asset management system 1 and the user terminal 3 via a network.

The user terminal 3 is a computer used by a user. A user is, for example, a customer who pays for a product (goods, service, etc.) to another user, who is a store, using crypto assets. Also, the user may be a store that pays another user, who is a store, using crypto assets. The user terminal 3 is, for example, a smart phone, a tablet terminal, or a personal computer. The user terminal 3 has an operation unit such as a touch panel or keyboard for receiving operations, a display unit such as a liquid crystal display for displaying information, and an imaging unit such as a camera for reading information. The user terminal 3 can communicate with the settlement server 2 via a network.

The outline of the processing executed by the information processing system S according to the present embodiment will be described below with reference to FIG. In the example shown in FIG. 1, after the crypto-assets are transferred to the first user by settlement by the third user (first transfer), the crypto-assets are transferred to the second user by settlement by the first user (second transfer). An example of processing executed by the information processing system S in the case of doing will be described. In FIG. 1, the first user terminal 3a is the user terminal 3 used by the first user, the second user terminal 3b is the user terminal 3 used by the second user, and the third user terminal 3c is the user terminal 3 used by the third user. A user terminal 3 to be used.

In this case, first, the first user terminal 3a transmits a payment request to the payment server 2 according to the operation by the first user ((1) in FIG. 1). The payment request includes, for example, identification information for identifying the first user (first user ID (Identification)), the second user's ID, and the cryptocurrency payment amount entered by the first user.

The settlement server 2 transmits to the crypto-asset management system 1 a transfer request for transferring the crypto-asset corresponding to the settlement amount included in the settlement request received from the first user terminal 3a from the first user to the second user ( (2) in FIG. 1). The transfer request includes, for example, the payment amount, the ID of the first user, and the ID of the second user.

The crypto-asset management system 1 transfers the crypto-asset corresponding to the settlement amount included in the transfer request received from the settlement server 2 from the first user's crypto-asset account to the second user's crypto-asset account (( 3)). The crypto-asset management system 1, for example, adds data to the blockchain indicating that the holder of the crypto-asset corresponding to the settlement amount is to be changed from the first user to the second user.

The settlement server 2 refers to the specific information for specifying the transfer history of the crypto-assets, and transfers the crypto-assets transferred from the first user to the second user (hereinafter referred to as “target assets”) to the first user. Identify the third user who was the previous owner and transferred the target asset to the first user ((4) in FIG. 1). Details of the specific information will be described later.

Then, the settlement server 2 provides the specified third user with a privilege for transferring the target asset from the first user to the second user ((5) in FIG. 1). The privilege is a privilege provided by a user different from the first user, the second user, and the third user (for example, a business operator that provides a predetermined service, a local government, a payment business operator that manages the payment server 2, etc.). There are, for example, points that can be used in services provided by the bearer of the privilege.

In this way, the information processing system S provides the third user with a privilege for transferring the target asset from the first user to the second user. As a result, the information processing system S can provide the user with motivation to preferentially use crypto assets over legal currency. As a result, the information processing system S can promote the use of crypto assets.
The configuration of the settlement server 2 will be described below.

[Description of account]
First, a method for managing crypto assets by the information processing system S will be described. FIG. 3 is a schematic diagram for explaining how the information processing system S manages crypto assets.

The crypto-asset management system 1 manages crypto-assets held by each of a plurality of users in crypto-asset accounts. Each of the plurality of users' crypto-asset accounts is associated with the user's ID (eg, the crypto-asset account's ID). The crypto-asset management system 1 manages crypto-assets by depositing and withdrawing crypto-assets to and from crypto-asset accounts, or transferring crypto-assets between a plurality of crypto-asset accounts.

The crypto-asset management system 1 manages crypto-assets using a coin as an asset unit, for example, using blockchain. The crypto-asset management system 1 stores, for example, a block (data) that associates a user's ID with transaction details in the user's crypto-asset account as a block chain on one or more storage devices on the network. do. Each block in the blockchain contains a hash value generated according to a predetermined rule, and by confirming the consistency of hash values between blocks, the correctness of the entire blockchain is guaranteed.

The crypto-asset management system 1 is not limited to blockchain, and for example, data that associates a user's ID, the balance of the user's crypto-asset account, and the content of one or more transactions in the user's crypto-asset account. may be stored as a database on the storage unit of the crypto-asset management system 1.

[Description of payment process]
Next, the configuration for the information processing system S to execute the process of settlement using cryptocurrency will be described below. In the payment server 2 , the reception unit 231 receives the payment request from the user terminal 3 . The payment request is a request for causing the crypto-asset management system 1 to transfer the payment amount from the crypto-asset account associated with the first user to the crypto-asset account associated with the second user. It includes the ID of the first user, the ID of the second user, and the settlement amount.

Specifically, first, the user terminal 3 transmits a payment request to the payment server 2 . For example, the user terminal 3 acquires the ID of the second user by reading the QR (Quick Response) code (registered trademark) presented by the second user, and the ID of the first user associated with the user terminal 3 Then, a payment request including the acquired ID of the second user and the amount of money to be settled by the crypto asset entered by the first user is transmitted to the payment server 2 . Then, in the payment server 2 , the reception unit 231 acquires the payment request from the user terminal 3 .

When the receiving unit 231 receives the payment request, the transfer processing unit 232 transfers the cryptographic assets held by the first user to the second user. Specifically, the transfer processing unit 232 instructs the crypto-asset management system 1 to transfer the settlement amount from the crypto-asset account associated with the first user to the crypto-asset account associated with the second user. of the transfer request to transfer the crypto assets held by the first user to the second user. The transfer request includes the ID of the first user, the ID of the second user, and the settlement amount.

Upon receiving the transfer request from the payment server 2, the crypto-asset management system 1 transfers the crypto-asset corresponding to the settlement amount included in the transfer request from the first user's crypto-asset account to the second user's crypto-asset account. For example, when managing cryptographic assets using a blockchain, the crypto-asset management system 1 changes the owner of the coin corresponding to the settlement amount from the first user to the second user. Add a block showing Further, for example, when the crypto-asset management system 1 manages the crypto-asset using a database, the crypto-asset management system 1 subtracts coins corresponding to the settlement amount from the first user's crypto-asset account in the database, Coins corresponding to the settlement amount may be added to the asset account.

The transfer processing unit 232 may preferentially transfer cryptographic assets that are used less frequently. Specifically, first, the number-of-times identification unit 233 identifies the number of times of use for settlement in the past for each asset unit, which is the unit in which the crypto-assets are circulated.

For example, when the crypto-asset management system 1 manages crypto-assets using a blockchain, the number-of-times identification unit 233 refers to the transactions stored in the blockchain for each asset unit, and determines the usage of the asset unit. Identify the number of times. For example, when the crypto-asset management system 1 manages crypto-assets using a database, the number-of-times identification unit 233 refers to the crypto-asset transfer history stored in the database for each asset unit, and Identify the number of times a unit is used.

Then, the transfer processing unit 232 preferentially transfers a cryptographic unit with a relatively small number of uses among the cryptographic assets held by the first user. The transfer processing unit 232 transfers, for example, the cryptographic unit with the least number of uses among the cryptoassets owned by the first user. By doing so, the settlement server 2 can reduce variations in the number of times of use.

The transfer processing unit 232 determines whether or not the second user satisfies the conditions for permission to use the crypto assets. Assets may be transferred to a second user. The conditions for permitting use are conditions for permitting the use of the crypto-assets, for which the conditions under which the use of the crypto-assets is permitted with respect to the payment of the price are defined. Whether or not the area allows the use of crypto assets, or whether or not the store allows the use of crypto assets. The usage permission condition may be whether or not the second user has a crypto asset account.

The transfer processing unit 232 determines whether or not the first user satisfies the payment conditions, and if it is determined that the first user satisfies the payment conditions, transfers the crypto assets held by the first user to the second user. may The payment condition is a condition for the source user to pay the price with the crypto assets, for example, whether or not the first user is a user who can use the crypto assets. For example, the transfer processing unit 232 inquires of the crypto-asset management system 1 whether or not the crypto-asset account of the first user exists, and based on the information transmitted by the crypto-asset management system 1 in response to the inquiry, the first Determine whether the user satisfies the payment conditions.

If the transfer processing unit 232 determines that the second user does not satisfy the conditions for permitting the use of the crypto assets, or if it determines that the first user does not satisfy the payment conditions, the transfer processing unit 232 notifies the first user that the crypto assets cannot be used. may notify you.

[Description of Granting Process]
Next, the configuration for the information processing system S to execute the process of giving a privilege will be described below. In the settlement server 2, when the transfer processing unit 232 transfers the crypto assets from the first user to the second user, the user identification unit 234 refers to the identification information for identifying the transfer history of the crypto assets. Identify users. The specific information is, for example, information stored in a block when crypto assets are managed using a blockchain, or in a database when crypto assets are managed using a database. The third user is a user who held cryptographic assets before the first user and who transferred the cryptographic assets to the first user.

For example, when the crypto-asset management system 1 manages the crypto-asset using a blockchain, the user identification unit 234 refers to the transaction stored in the blockchain and refers to the crypto-asset held immediately before the first user. identify the third user who was When the crypto-asset management system 1 manages the crypto-asset using a database, the user specifying unit 234 refers to the transfer history of the crypto-asset used by the first user in the database, and transfers the crypto-asset immediately before the first user. Identify the third user who owned the asset.

The privilege providing unit 235 provides a privilege provided by another user different from the first user, the second user, and the third user, which is a privilege for the first user transferring the crypto assets to the second user. 3 Give to users. For example, the storage unit 22 stores points (privileges) owned by each of a plurality of users, and the privilege granting unit 235 adds the points to be granted to the points owned by the third user, 3 Give a privilege to the user.

The privilege granting unit 235 may grant a privilege according to the usage amount of the target asset (the cryptographic asset transferred from the first user to the second user) used for payment. For example, the privilege granting unit 235 grants more points as the usage amount of the target asset is larger, and grants fewer points as the usage amount of the target asset is smaller. For example, a coefficient for calculating points is predetermined in the storage unit 22, and the privilege granting unit 235 calculates points by multiplying the usage amount of the target asset used by the first user by the coefficient. , gives the calculated points to the third user. By doing so, the settlement server 2 can give a privilege to the third user according to the use of the target asset by the first user.

The privilege granting unit 235 may grant a privilege according to the holding period during which the target asset was held by the first user or the holding period during which the target asset was held by the third user. For example, the privilege granting unit 235 grants fewer points as the holding period of the target asset is longer, and grants more points as the holding period of the target asset is shorter.

For example, first, the privilege granting unit 235 identifies the holding period for each asset unit of the target asset. Then, the privilege granting unit 235 calculates points by totaling the coefficients corresponding to the holding periods specified for each asset unit, and grants the calculated points. The coefficient is a predetermined numerical value for each holding period. For example, in the settlement server 2, a coefficient that is smaller for a longer holding period and larger for a shorter holding period is set in advance. By doing so, the settlement server 2 can provide motivation to use the crypto asset as soon as possible.

The privilege granting unit 235 may grant a privilege according to the balance of the resource of the privilege. Specifically, the privilege granting unit 235 grants the privilege to the third user when the amount of the privilege is smaller than the balance of the resource for the privilege. On the other hand, the privilege granting unit 235 prohibits granting the privilege to the third user when the amount of the privilege is larger than the balance of the resource for the privilege. By doing so, the settlement server 2 can prevent granting of benefits in excess of the resources for the benefits.

The privilege granting unit 235 may grant the privilege to the third user when the second user and the third user are not the same user. For example, when the ID of the second user and the ID of the third user are not the same, the privilege giving unit 235 gives the privilege to the third user, and the ID of the second user and the ID of the third user are the same. In the case of , it is prohibited to give the privilege to the third user. By doing so, the settlement server 2 can prevent repeated granting of benefits due to repeated transfers of cryptographic assets between specific users.

The payment server 2 may provide information regarding the first user who used cryptocurrency. The information about the first user is, for example, the name of the first user. Specifically, the notification unit 236 notifies the third user to whom the privilege has been given of the information regarding the first user who used the crypto assets. By doing so, the settlement server 2 can provide the third user with a motivation to use the crypto-assets for the first user who has a track record of using the crypto-assets.

[Sequence of information processing method]
FIG. 4 is a sequence diagram of an exemplary information processing method executed by the information processing system S according to this embodiment. The processes of S4 and S5 shown in FIG. 4 may be performed before the processes of S2 and S3. This process starts when the first user terminal 3a transmits a payment request including the ID of the first user, the ID of the second user, and the payment amount to the payment server 2 (S1).

In the payment server 2, when the reception unit 231 acquires the payment request from the first user terminal 3a, the transfer processing unit 232 notifies the crypto-asset management system 1 of the transfer request (S2). When the crypto-asset management system 1 acquires the transfer request from the settlement server 2, the crypto-asset management system 1 transfers the crypto-asset corresponding to the settlement amount included in the transfer request from the crypto-asset account associated with the ID of the first user to the ID of the second user. is transferred to the crypto asset account associated with (S3).

The user identification unit 234 refers to the identification information and determines whether or not the third user exists (S4). When the user specifying unit 234 determines that the third user does not exist (NO in S4), the process ends. On the other hand, when the user specifying unit 234 determines that the third user exists (YES in S4), that is, when the user specifying unit 234 specifies the third user, the privilege granting unit 235 gives the specified third user A privilege is given (S5).

[Modification]
In the above description, the information processing system S explained an example in which the third user is given a privilege for transferring the target asset from the first user to the second user, but the present invention is not limited to this. For example, the information processing system S may give a privilege to the first user who transferred the target asset to the second user.

Also, for example, the information processing system S may give a privilege to another user who owned the target asset before the third user. The other users include a fourth user who owned immediately before the third user and a fifth user who owned before the fourth user. In the information processing system S, when the first user transfers the target asset to the second user, all users who held the target asset in the past (third user, fourth user, fifth user, etc.) give benefits to

The information processing system S may give a benefit to users who owned the target asset in the past and whose ownership generation who owned the target asset is within a predetermined range. For example, in the target asset, the first holding generation is the fifth user, the second holding generation is the fourth user, the third holding generation is the third user, and the fourth holding generation is the first user. , the fifth owned generation is the second user, and the predetermined range is from the second owned generation to the third owned generation. In this case, the information processing system S provides benefits to the third and fourth users who belong to the second to third ownership generations among the users who owned the target asset in the past. Give.

When giving points to a plurality of generations, the information processing system S gives fewer points to owned generations with a smaller number of generations (for example, the first owned generation), and gives less points to owned generations with a larger number of generations (for example, the fifth owned generation). A larger number of points may be given to the older generation. For example, when the information processing system S gives benefits to the third user who is the third owner generation and the fourth user who is the second owner generation, the points given to the third user are given to the fourth user Give more points than you give to. The information processing system S may give more points to owned generations with a smaller number of generations, and may give fewer points to owned generations with a larger number of generations.

[Effects of this embodiment]
As described above, the information processing system S provides the third user with a privilege for transferring the target asset from the first user to the second user. As a result, the information processing system S can provide the user with motivation to preferentially use crypto assets over legal currency. As a result, the information processing system S can promote the use of crypto assets.
