FIG. 1 is a schematic diagram of an information processing system according to the present embodiment. FIG. 2 is a block diagram of a payment server according to the present embodiment. FIG. 2 is a schematic diagram for explaining how the information processing system manages cryptographic assets. FIG. 2 is a sequence diagram of an exemplary information processing method executed by the information processing system according to the present embodiment.

[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 cryptographic asset management system 1, a payment server 2, and a user terminal 3. The information processing system S may include other devices such as servers and terminals.

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

Crypto assets are, for example, electronic assets managed by blockchain. Further, the cryptographic asset is not limited to a blockchain, but may be an electronic asset managed by a database or the like. Crypto assets are managed in asset units, which are predetermined units (for example, circulating units) used for settlement. Hereinafter, the asset unit of crypto assets will be referred to as a coin, but other names may be used.

The crypto asset may be a regional digital currency available in a predetermined region. For example, a payment using a crypto asset that is a regional digital currency can be performed at a store within a predetermined region, but cannot be performed at a store outside the region. Further, payments using cryptographic assets, which are regional digital currencies, may be possible only at predetermined stores (eg, registered stores) within a predetermined area.

The crypto asset may be a regional digital currency available to a given user. For example, payments using crypto assets, which are regional digital currencies, can be made at stores within a given region in response to a request from a given user, and payments made using crypto assets, which are regional digital currencies, can be made at stores within a given region in response to a request by a user other than the given user. Impracticable in stores. For a predetermined region and a predetermined user, it is determined, for example, by the bearer who has paid the funds to have the crypto asset issued.

The crypto asset management system 1 manages crypto assets held by each user in a crypto asset account associated with the user. For example, the crypto asset management system 1 transfers crypto assets from one user's crypto asset account to another user's crypto asset account in response to a transfer request received from the payment server 2. The crypto asset management system 1 is capable of communicating with the payment server 2 and user terminal 3 via a network.

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

The user terminal 3 is a computer used by a user. A user is, for example, a customer who uses crypto assets to pay for products (goods, services, etc.) to another user at a store. Alternatively, the user may be a store that uses crypto assets to pay for another user who is a store. The user terminal 3 is, for example, a smartphone, a tablet terminal, or a personal computer. The user terminal 3 includes an operation section such as a touch panel or a keyboard for receiving operations, a display section such as a liquid crystal display for displaying information, and an imaging section such as a camera for reading information. The user terminal 3 can communicate with the payment server 2 via the network.

Below, an overview of the processing executed by the information processing system S according to this embodiment will be explained using FIG. 1. In the example shown in Figure 1, after the crypto asset is transferred to the first user through payment by the third user (first transfer), the crypto asset is transferred to the second user through payment by the first user (second transfer). An example of processing executed by the information processing system S in the case where the information processing system S performs the following 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. This is the user terminal 3 to be used.

In this case, first, the first user terminal 3a transmits a payment request to the payment server 2 in response to an operation by the first user ((1) in FIG. 1). The payment request includes, for example, identification information for identifying the first user (ID (Identification) of the first user), the ID of the second user, and the payment amount of the crypto asset input by the first user.

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

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

The payment server 2 refers to specific information for identifying the history of transfer of 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. The third user who previously owned the asset and transferred the target asset to the first user is identified ((4) in FIG. 1). Details of the specific information will be described later.

Then, the payment server 2 grants the specified third user a benefit for transferring the target asset to the second user by the first user ((5) in FIG. 1). The benefit is a benefit provided by another user different from the first user, the second user, and the third user (for example, a business providing a predetermined service, a local government, a payment provider managing the payment server 2, etc.). For example, these are points that can be used in services provided by the person who pays for the benefit.

In this way, the information processing system S provides the third user with a benefit for the first user transferring the target asset to the second user. Thereby, 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 cryptographic assets.
The configuration of the payment server 2 will be described below.

[Configuration of payment server 2]
FIG. 2 is a block diagram of the payment server 2 according to this embodiment. In FIG. 2, arrows indicate main data flows, and data flows other than those shown in FIG. 2 may exist. In FIG. 2, each block shows the configuration of a functional unit rather than a hardware (device) unit. Therefore, the blocks shown in FIG. 2 may be implemented within a single device, or may be implemented separately within multiple devices. Data may be exchanged between blocks via any means such as a data bus, network, or portable storage medium.

The payment server 2 includes a communication section 21, a storage section 22, and a control section 23. The payment server 2 may be configured by two or more physically separate devices connected by wire or wirelessly. Further, the payment server 2 may be configured by a cloud that is a collection of computer resources.

The communication unit 21 includes a communication controller for transmitting and receiving data between the cryptographic asset management system 1 and the user terminal 3 via the network. The communication unit 21 notifies the control unit 23 of data received from the cryptographic asset management system 1 or the user terminal 3 via the network. Furthermore, the communication unit 21 transmits the data output from the control unit 23 to the cryptographic asset management system 1 or the user terminal 3 via the network.

The storage unit 22 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk drive, and the like. The storage unit 22 stores in advance a program to be executed by the control unit 23. The storage unit 22 may be provided outside the payment server 2, and in that case, data may be exchanged with the control unit 23 via a network.

The control unit 23 includes a receiving unit 231 , a transfer processing unit 232 , a frequency specifying unit 233 , a user specifying unit 234 , a privilege granting unit 235 , and a notification unit 236 . The control unit 23 is, for example, a processor such as a CPU (Central Processing Unit), and executes a program stored in the storage unit 22 to control the reception unit 231, the transfer processing unit 232, the number of times identification unit 233, and the user identification unit 234. , functions as a privilege granting section 235 and a notification section 236. Processes performed by each of the receiving section 231, transfer processing section 232, frequency specifying section 233, user specifying section 234, privilege granting section 235, and notification section 236 will be described later.

[Account description]
First, a method for the information processing system S to manage cryptographic assets will be explained. FIG. 3 is a schematic diagram for explaining how the information processing system S manages cryptographic assets.

The crypto asset management system 1 manages crypto assets held by each of a plurality of users in a crypto asset account. The crypto asset accounts of each of the plurality of users are associated with the user's ID (for example, the ID of the crypto asset account). The crypto asset management system 1 manages crypto assets by depositing and withdrawing crypto assets into and out of a crypto asset account, or transferring crypto assets between multiple crypto asset accounts.

The crypto asset management system 1 uses, for example, blockchain to manage crypto assets using coins as asset units. The crypto asset management system 1 stores, for example, a block (data) that associates a user's ID with the content of transactions in the user's crypto asset account as a blockchain 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 checking the consistency of hash values between blocks, the correctness of the entire blockchain is ensured.

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 contents of one or more transactions in the user's crypto asset account. may be stored as a database on the storage unit included in the cryptographic asset management system 1.

[Explanation of payment processing]
Next, a configuration for the information processing system S to execute processing for making payments using cryptographic assets will be described below. In the payment server 2, the receiving unit 231 receives a 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 an ID of one user, an ID of a second user, and a payment amount.

Specifically, first, the user terminal 3 transmits a payment request to the payment server 2. For example, the user terminal 3 acquires the second user's ID by reading a QR (Quick Response) code (registered trademark) presented by the second user, and acquires 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 payment amount using the crypto asset input by the first user is transmitted to the payment server 2. Then, in the payment server 2, the receiving 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 transfers the settlement amount to the crypto asset management system 1 from the crypto asset account associated with the first user to the crypto asset account associated with the second user. By notifying the transfer request of , the cryptographic assets held by the first user are transferred to the second user. The transfer request includes the first user's ID, the second user's ID, and the payment amount.

Upon acquiring the transfer request from the payment server 2, the crypto asset management system 1 transfers the crypto asset corresponding to the payment 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 crypto assets using a blockchain, the crypto asset management system 1 can change the holder of the coin corresponding to the payment amount from the first user to the second user on the blockchain. Add a block that shows. In addition, when the crypto asset management system 1 manages crypto assets using a database, for example, the crypto asset management system 1 subtracts coins corresponding to the payment amount from the first user's crypto asset account in the database, and Coins corresponding to the payment amount may be added to the asset account.

The transfer processing unit 232 may preferentially transfer cryptographic assets that have been used less frequently. Specifically, first, the number identification unit 233 identifies the number of times each asset unit, which is a unit in which cryptographic assets are distributed, has been used for settlement in the past.

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

Then, the transfer processing unit 232 preferentially transfers cryptographic units that have been used relatively few times among the cryptographic assets held by the first user. For example, the transfer processing unit 232 transfers the cryptographic unit that has been used the least number of times among the cryptographic assets held by the first user. By doing so, the payment server 2 can reduce the variation in the number of uses.

The transfer processing unit 232 determines whether or not the second user satisfies the conditions for permission to use the crypto asset, and if it is determined that the second user satisfies the conditions for permission to use the crypto asset, the transfer processing unit 232 transfers the crypto assets held by the first user. The assets may be transferred to a second user. Usage permission conditions are conditions for permitting the use of crypto assets that specify the conditions under which usage is permitted for payment of the price.For example, if the area where the store that is the second user is located is These include whether the area is where crypto assets can be used, or whether the store is a store where crypto assets can be used. The usage permission condition may be whether or not the second user has a crypto asset account.

The transfer processing unit 232 determines whether 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. It's okay. The payment conditions are conditions for the source user to pay with the cryptographic asset, such as whether or not the first user is a user who can use the cryptographic asset. For example, the transfer processing unit 232 inquires of the crypto asset management system 1 whether or not the first user's crypto asset account exists, and based on the information sent by the crypto asset management system 1 in response to the inquiry, transfers the first user to the first user. 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 permission to use 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. You may notify.

[Description of grant processing]
Next, the configuration for the information processing system S to execute the process of awarding benefits will be described below. In the payment server 2, when the transfer processing unit 232 transfers the crypto asset from the first user to the second user, the user specifying unit 234 refers to the specific information for specifying the transfer history of the crypto asset and transfers the crypto asset to the third user. Identify the user. The specific information is, for example, a block when managing cryptographic assets using a blockchain, or information stored in a database when managing cryptographic assets using a database. The third user is a user who held the cryptographic asset before the first user and is a user who transferred the cryptographic asset to the first user.

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

The benefit granting unit 235 provides a benefit for the transfer of crypto assets by the first user to the second user, which is provided by another user different from the first user, the second user, and the third user. Granted to 3 users. For example, the storage unit 22 stores points (benefits) held by each of a plurality of users, and the benefit giving unit 235 adds the points to be given to the points held by the third user. Give benefits to 3 users.

The benefit granting unit 235 may grant a benefit according to the usage amount of the target asset (the cryptographic asset transferred by the first user to the second user) used for payment. For example, the benefit granting unit 235 grants more points as the usage amount of the target asset is larger, and gives 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 benefit granting unit 235 calculates the 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 payment server 2 can provide benefits to the third user in accordance with the use of the target asset by the first user.

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

For example, first, the benefit granting unit 235 identifies the holding period for each asset unit of the target asset. Then, the benefit granting unit 235 calculates points by summing up the coefficients corresponding to each of the holding periods specified for each asset unit, and grants the calculated points. The coefficient is a predetermined value for each holding period. For example, the payment server 2 has a predetermined coefficient that is smaller as the holding period is longer and larger as the holding period is shorter. By doing so, the payment server 2 can provide motivation for early use of crypto assets.

The benefit granting unit 235 may grant a benefit according to the balance of the fund for the benefit. Specifically, the benefit granting unit 235 grants the benefit to the third user when the amount of the benefit is smaller than the balance of funds for the benefit. On the other hand, the benefit granting unit 235 prohibits granting the benefit to the third user if the amount of the benefit is greater than the balance of the funds for the benefit. By doing so, the payment server 2 can prevent awarding benefits in excess of the source of the benefits.

The benefit granting unit 235 may grant a benefit to the third user when the second user and the third user are not the same user. For example, if the second user's ID and the third user's ID are not the same, the benefit granting unit 235 grants the benefit to the third user, and if the second user's ID and the third user's ID are the same, If so, the provision of benefits to the third user is prohibited. By doing so, the payment server 2 can prevent the 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 the cryptographic asset. The information regarding 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 granted of information regarding the first user who used the cryptographic asset. By doing so, the payment server 2 can provide the third user with motivation to use the cryptographic asset for the first user who has a history of using the cryptographic asset.

[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 the present embodiment. The processes in S4 and S5 shown in FIG. 4 may be executed before the processes in S2 and S3. This process starts when the first user terminal 3a transmits a payment request including the first user's ID, the second user's ID, and the payment amount to the payment server 2 (S1).

In the payment server 2, when the receiving 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). Upon acquiring the transfer request from the payment server 2, the crypto asset management system 1 transfers the crypto assets corresponding to the payment amount included in the transfer request from the crypto asset account associated with the first user's ID to the second user's ID. (S3).

The user identification unit 234 refers to the identification information and determines whether a 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, if the user specifying unit 234 determines that the third user exists (YES in S4), that is, if the user specifying unit 234 specifies the third user, the privilege granting unit 235 A benefit is granted (S5).

[Modified example]
In the above, the information processing system S has explained an example in which the first user gives a benefit to the third user for transferring the target asset to the second user, but the present invention is not limited to this. For example, the information processing system S may provide a benefit to the first user who transferred the target asset to the second user.

Further, for example, the information processing system S may grant a benefit to another user who owned the target asset before the third user. The other users include the fourth user who held the item immediately before the third user, and the fifth user who held the item before the fourth user. When the first user transfers the target asset to the second user, the information processing system S transfers the target asset to all users (third user, fourth user, fifth user, etc.) who held the target asset in the past. Give benefits to.

The information processing system S may grant benefits to users whose owning generation who owned the target asset is within a predetermined range among users who have owned the target asset in the past. For example, in a target asset, the first ownership generation is the fifth user, the second ownership generation is the fourth user, the third ownership generation is the third user, and the fourth ownership generation is the first user. Assume that the fifth ownership generation is the second user and the predetermined range is from the second ownership generation to the third ownership generation. In this case, the information processing system S provides benefits to the third and fourth users who fall from the second ownership generation to the third ownership generation among the users who have owned the target asset in the past. Give.

When assigning points to multiple generations, the information processing system S assigns fewer points to the ownership generation with a smaller number of generations (for example, the first ownership generation), and gives fewer points to the ownership generation with a larger number of generations (for example, the fifth ownership generation). The higher the ownership generation), the more points may be awarded. For example, when granting benefits to a third user who is the third ownership generation and a fourth user who is the second ownership generation, the information processing system S transfers the points given to the third user to the fourth user who is the second ownership generation. More points will be awarded than those given to. Note that the information processing system S may assign more points to a ownership generation with a smaller number of generations, and may grant fewer points to a ownership generation with a larger number of generations.

[Effects of this embodiment]
As explained above, the information processing system S grants the third user a benefit for the first user transferring the target asset to the second user. Thereby, 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 cryptographic assets.

Furthermore, the present invention makes it possible to contribute to Goal 9 of the Sustainable Development Goals (SDGs) led by the United Nations, "Create a foundation for industry and technological innovation."
