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

The management server 1 (information processing device) is a computer for managing information related to cryptographic assets as well as registration data, which is electronic data traded between users. Management server 1 is capable of communicating with user terminals 2 via a network.

Crypto assets are electronic assets that can be used for payment, etc., and are different from legal currencies (Japanese yen, US dollar, etc.). 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. Cryptoassets are issued to users by issuers such as local governments and companies. A cryptographic asset is associated with a user who holds the cryptographic asset, for example, in a storage device, and is transferred from one user to another 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.

In this embodiment, the cryptographic asset is, for example, a regional digital currency that can be used in a predetermined region. Payments using crypto assets, which are regional digital currencies, can be executed at stores within a predetermined area, but cannot be executed at stores outside the area. Further, payments using cryptographic assets, which are regional digital currencies, may be possible only at predetermined stores (eg, registered stores) within a predetermined region.

Furthermore, when products are bought and sold between two users (for example, bought and sold on a website for transactions between individuals), the individual users who sell the products may be treated as stores. In this case, it may be determined whether the store is within the area based on the address of the user who sells the product.

The management server 1 manages cryptographic assets held by each user in a cryptographic asset account associated with the user. The management server 1 transfers the cryptographic asset from one user's cryptographic asset account to another user's cryptographic asset account, for example, by changing the holder of the cryptographic asset from one user to another user in the blockchain.

Registration data is electronic data such as paintings, photographs, music, programs, game characters and items, etc. that are traded between users. The user owns the registered data by, for example, being recorded in the storage device as having ownership of the registered data.

The ownership of registered data is managed as an NFT (Non-Fungible Token) using a blockchain, for example. NFT is information indicating, for example, data identification information (data ID) for identifying registered data and user identification information (user ID) for identifying a user who owns the registered data. The data ID is, for example, a URI (Uniform Resource Identifier) for accessing registered data. The registration data is stored in a storage device on the network corresponding to the URI. Furthermore, ownership of registered data is not limited to blockchain, and may be managed using a database or the like.

The management server 1 manages ownership of each user's registered data in a data management account associated with the user. For example, the management server 1 transfers ownership of registered data from one user's data management account to another user's data management account by changing the owner of the registered data from one user to another in the blockchain. do.

The user terminal 2 is a computer used by users such as registrants and purchase requesters. The registrant is, for example, a user who has registered registration data with the management server 1. The purchase requester is, for example, a user who desires to purchase registered data using cryptographic assets. The user terminal 2 is, for example, a smartphone, a tablet terminal, or a personal computer. The user terminal 2 includes an operation section such as a touch panel or a keyboard for receiving operations, and a display section such as a liquid crystal display for displaying information. The user terminal 2 can communicate with the management server 1 via the network.

An overview of the processing executed by the information processing system S according to this embodiment will be described below. The management server 1 receives a registration request for registering registration data from a user terminal 2 used by a registrant (1). The registration request is, for example, information indicating the data ID of the registration data and the user ID of the registrant.

In response to the registration request, the management server 1 associates and registers the data ID of the registration data and the user ID of the registrant. As a result, the registrant becomes the holder of the registered data at the time the registered data is registered. Thereafter, when ownership of the registered data is transferred due to transfer between users, a user different from the registrant becomes the holder of the registered data.

The management server 1 receives a purchase request for purchasing registered data from the user terminal 2 used by the purchase requester (2). The purchase request is, for example, information indicating the user ID of the purchase requester and the cryptographic assets used for the purchase.

The management server 1 determines whether the registered data can be purchased with cryptographic assets based on the relationship between the registrant's attributes and the conditions under which the cryptographic assets can be used (3). The management server 1 determines that registered data can be purchased with cryptographic assets, for example, when attributes of the registrant, such as location, nationality, age, and gender, satisfy conditions associated with cryptographic assets in advance.

On the condition that it is determined that the registered data can be purchased with crypto assets, the management server 1 changes the user who holds the crypto assets from the purchase requester to the holder (4), and holds the registered data. The user is changed from a holder to a purchase requester (5). As a result, the crypto asset corresponding to the price of the registered data is paid from the purchase requester to the holder, and the purchase requester becomes the new holder of the registered data.

In this manner, the information processing system S allows a purchase requester to purchase registered data with cryptographic assets, provided that the attributes of the registrant who has registered the registered data satisfy the conditions under which the cryptographic assets can be used. As a result, the information processing system S can limit the use of cryptographic assets to the purchase of registered data registered by users with specific attributes, thereby activating economic circulation among users with specific attributes.

[Configuration of information processing system S]
FIG. 2 is a block diagram of the information processing system S 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 management server 1 includes a communication section 11, a storage section 12, and a control section 13. The management server 1 may be configured by two or more physically separate devices connected by wire or wirelessly. Furthermore, the management server 1 may be configured by a cloud that is a collection of computer resources.

The communication unit 11 includes a communication controller for transmitting and receiving data to and from the user terminal 2 via the network. The communication unit 11 notifies the control unit 13 of data received from the user terminal 2 via the network. Furthermore, the communication unit 11 transmits data output from the control unit 13 to the user terminal 2 via the network.

The storage unit 12 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 12 stores in advance a program to be executed by the control unit 13. Furthermore, the storage unit 12 stores in advance attribute information indicating the attributes of the registrant of the registration data. Furthermore, the storage unit 12 stores in advance usage conditions that are conditions under which the cryptographic asset can be used. Furthermore, the storage unit 12 stores in advance the price of the registered data specified by the holder of the registered data. The storage unit 12 may be provided outside the management server 1, and in that case, data may be exchanged with the control unit 13 via a network.

The control unit 13 includes a registration unit 131, a registered data processing unit 132, a reception unit 133, a determination unit 134, an output unit 135, and a cryptographic asset processing unit 136. The control unit 13 is, for example, a processor such as a CPU (Central Processing Unit), and executes a program stored in the storage unit 12 to control the registration unit 131, registered data processing unit 132, reception unit 133, determination unit 134, It functions as an output unit 135 and a crypto asset processing unit 136. Processes performed by each of the registration unit 131, registered data processing unit 132, reception unit 133, determination unit 134, output unit 135, and cryptographic asset processing unit 136 will be described later.

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

The management server 1 manages cryptographic assets held by each of a plurality of users in a cryptographic asset account. The crypto asset account of each of the plurality of users is associated with the user ID of the user. The management server 1 manages cryptographic assets by depositing and withdrawing cryptographic assets into and out of cryptographic asset accounts, or by transferring currency between multiple cryptographic asset accounts.

The management server 1 uses, for example, blockchain to manage cryptographic assets using coins as asset units. For example, the management server 1 stores data (blocks) that associates a user's user ID with the details of transactions in the user's crypto asset account as a blockchain on one or more storage devices on the network. . Each block includes one or more transactions indicating the transfer of cryptoassets between users' cryptoassets accounts. 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 management server 1 is not limited to blockchain, and for example, stores data in which a user's user ID is associated with the crypto assets managed in the user's crypto asset account on the storage unit 12 of the management server 1. It may also be stored as a database.

The management server 1 manages registered data held by each of a plurality of users in a data management account. The data management account of each of the plurality of users is associated with the user ID of the user. In order to manage registered data, the management server 1 grants ownership of registered data to a data management account, or transfers ownership of registered data between a plurality of data management accounts.

The management server 1 manages ownership of registered data using, for example, blockchain. For example, the management server 1 blocks data (block) indicating an NFT in which the data ID of the registered data is associated with the user ID of the user who owns the registered data on one or more storage devices on the network. Store as a chain. Each block includes one or more transactions indicating that NFTs were transferred between users' data management accounts. 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 management server 1 is not limited to a blockchain, and for example, the storage unit 12 in which the management server 1 has data that associates a user's ID with the ownership of registered data managed in the data management account of the user. It may also be stored as a database on the computer.

It is desirable that the data ID of the registered data (for example, the above-mentioned NFT) and the cryptographic assets used to purchase the registered data are managed on the same platform. In this case, the platform used by the management server 1 is a platform that records both data IDs and cryptographic assets using one blockchain. Thereby, the management server 1 can manage the data ID of the registered data and the cryptographic assets on a common platform, and can reduce the effort of system maintenance and operation.

Users associated with data management accounts (for example, users who hold registered data) and users associated with crypto asset accounts (for example, users who hold crypto assets) are managed using a common user ID. It is desirable that Thereby, the management server 1 can enable the user to easily grasp the ownership status of registered data and cryptographic assets using one user ID.

[Explanation of registration process]
The configuration for the information processing system S to execute the process of registering registration data will be described below. The user terminal 2 used by the registrant transmits a registration request for registering registration data to the management server 1 in response to a predetermined operation performed by the registrant. The registration request is, for example, information indicating the data ID of the registration data and the user ID of the registrant.

In the management server 1, the registration unit 131 receives a registration request from the user terminal 2. The registration unit 131 registers registration data by notifying the registration data processing unit 132 of information for associating the data ID and user ID indicated by the registration request and storing them in the storage device. The registered data processing unit 132 grants ownership of the registered data to the registrant according to the information notified from the registration unit 131. For example, the registration data processing unit 132 adds, to the blockchain, a transaction indicating that an NFT associated with the data ID and user ID indicated by the registration request is to be registered in the data management account of the registrant. As a result, the registrant becomes the holder of the registered data at the time the registered data is registered.

When the ownership of registered data is transferred due to transfer or the like between users, the registered data processing unit 132 transfers the ownership of the registered data between users. For example, the registered data processing unit 132 transfers the ownership of the registered data to be transferred from the data management account of the holder before the transfer (i.e., the registrant or other user) to the data of the holder after the transfer. Add a transaction to indicate the transfer to a managed account. Hereinafter, a user who has ownership of the registered data at the time the registered data is traded will be referred to as the holder of the registered data.

[Explanation of transfer process]
The configuration for the information processing system S to execute the process of transferring ownership of registered data will be described below. In the management server 1, the reception unit 133 acquires the user ID of the registrant and holder of the registered data based on information stored in the blockchain or database. Further, the reception unit 133 acquires the attribute information of the registrant of the registration data, which is stored in the storage unit 12 in advance. Further, the reception unit 133 acquires the price of the registration data stored in the storage unit 12 in advance. When multiple pieces of registered data are registered in the blockchain or database, the management server 1 performs subsequent processing for each piece of registered data.

The reception unit 133 transmits registered data information including the user IDs of the registrant and the holder, the attribute information of the registrant, and the price of the registered data to the user terminal 2 used by the purchase requester. The user terminal 2 displays the registered data information received from the management server 1 on the display unit. When a purchase requester wishes to purchase registered data held by a holder, the purchase requester specifies the cryptographic asset to be used for purchasing the registered data on the user terminal 2 used by the purchase requester.

FIG. 4 is a schematic diagram of an exemplary screen displayed by the user terminal 2 in this embodiment. For example, based on the registered data information received from the management server 1, the user terminal 2 stores the contents of the registered data held by the holder, the user ID of the registrant and holder of the registered data, and the registrant's attribute information ( In FIG. 4, the registrant's location) and the price of the registered data are displayed on the display section.

The user terminal 2 accepts the designation of cryptographic assets to be used for purchasing registered data. In response to a predetermined operation performed by a purchase requester, the user terminal 2 transmits a purchase request to the management server 1 to purchase registered data held by the holder using cryptographic assets. The purchase request is, for example, information indicating the user ID of the purchase requester, the data ID of the registered data to be purchased, and the cryptographic asset designated by the purchase requester.

In the management server 1, the reception unit 133 receives a purchase request from the user terminal 2. The determination unit 134 acquires, for example, attribute information that is stored in advance in the storage unit 12 and indicates the attributes of the registrant who has registered the registration data corresponding to the data ID indicated by the purchase request. Attribute information includes, for example, the region (location, etc.) associated with the registrant, the registrant's nationality, the registrant's age, the registrant's gender, and the qualifications the registrant has (prescribed national qualifications, etc.). This is information indicating at least one of .

Based on the relationship between the attributes of the registrant indicated by the acquired attribute information and the cryptographic asset indicated by the purchase request, the determination unit 134 determines whether the registered data corresponding to the data ID indicated by the purchase request can be purchased with the cryptographic asset. Determine whether or not.

The determination unit 134 obtains, for example, usage conditions that are stored in advance in the storage unit 12 and are conditions under which the cryptographic asset can be used. For example, the availability condition is such that at least one of the following is a predetermined value: the region associated with the registrant, the registrant's nationality, the registrant's age, the registrant's gender, and the registrant's qualifications. or within a predetermined range. The determination unit 134 determines that the registered data can be purchased with crypto assets if the attributes of the registrant indicated by the attribute information satisfy the acquired usage conditions, and if not, the determination unit 134 determines that the registered data can be purchased with crypto assets. It is determined that it is not available for purchase.

As will be described later in a modification, the determination unit 134 may determine whether the registered data can be purchased with crypto assets before the reception unit 133 accepts the purchase request.

FIGS. 5A and 5B are schematic diagrams for explaining a method in which the determination unit 134 determines whether registered data can be purchased with cryptographic assets. FIG. 5A shows an example in which the determination unit 134 makes a determination based on the area associated with the registrant.

In this case, for example, the cryptographic asset can be used for payment at a store within a predetermined usable area, but cannot be used for payment at a store outside the usable area. Cryptoassets are issued, for example, by local governments that have jurisdiction over the areas where they can be used. The availability condition is that the area associated with the registrant is included in the area where the crypto asset can be used.

The determining unit 134 compares the area associated with the registrant indicated by the registrant's attributes with the area where the crypto asset can be used. The area associated with the registrant is, for example, an area under the jurisdiction of the local government that is the registrant, or an area where the store that is the registrant is located. For example, the determination unit 134 determines that the registered data can be purchased with crypto assets if the registrant is a local government that has jurisdiction over the available area or a store within the available area, and if not. It is determined that the registered data cannot be purchased with crypto assets.

As a result, the management server 1 can restrict the use of crypto assets to the purchase of registered data registered by registrants related to the area where the crypto assets can be used, thereby suppressing the outflow of the crypto assets outside the area where the crypto assets can be used. , it is possible to revitalize economic circulation in the area where it can be used.

FIG. 5B shows an example in which the determination unit 134 makes a determination based on attributes of the registrant other than the area associated with the registrant. The determination unit 134 converts at least one of the registrant's nationality, the registrant's age, the registrant's gender, and the registrant's qualifications indicated by the registrant's attributes into a value indicated by the availability condition or Compare with range. The determination unit 134 determines, for example, if the registrant has the nationality of a specific country, if the registrant is of a specific age (young or elderly), if the registrant is of a specific gender, or if the registrant is of a specific gender. If the user has a specific qualification, the registered data is determined to be purchasable with cryptographic assets; otherwise, it is determined that the registered data is not purchasable with cryptographic assets.

As a result, the management server 1 can restrict the use of crypto assets to the purchase of registered data registered by registrants with specific attributes, thereby suppressing the leakage of crypto assets to users with specific attributes, and It is possible to revitalize economic circulation among users with these attributes.

The output unit 135 determines that the registered data cannot be purchased with the crypto assets indicated by the purchase request, on the condition that the reception unit 133 receives the purchase request and the determination unit 134 determines that the registered data cannot be purchased with the crypto assets. information indicating this is transmitted to the user terminal 2. The user terminal 2 displays the information received from the management server 1 on the display unit.

FIG. 6 is a schematic diagram of a screen displayed by the user terminal 2 in this embodiment. For example, based on the information received from the management server 1, the user terminal 2 displays a message on the display unit indicating that the registered data cannot be purchased with the cryptographic assets specified by the purchase requester. Thereby, the user can easily understand that the registered data cannot be purchased with the specified cryptographic asset, and can make a request to purchase the registered data using another cryptographic asset.

On the other hand, the output unit 135 changes the user who owns the crypto asset indicated by the purchase request from the purchase requester to the holder, on the condition that the determination unit 134 determines that the registered data can be purchased with crypto assets. and a registered data transfer instruction to change the user who holds the registered data from the holder to the purchase requester. The cryptographic asset transfer instruction is, for example, information indicating the user ID of the purchase requester, the user ID of the holder, and the amount of the cryptographic asset corresponding to the price of the registered data. The registered data transfer instruction is, for example, information indicating the user ID of the purchase requester, the user ID of the holder, and the data ID of the registered data.

The output unit 135 notifies the crypto asset processing unit 136 of the crypto asset transfer instruction. The crypto asset processing unit 136 transfers the crypto asset corresponding to the price of the registered data from the purchase requester's crypto asset account to the holder's crypto asset account in accordance with the crypto asset transfer instruction output by the output unit 135. For example, the crypto asset processing unit 136 sends a transaction to the blockchain indicating that one or more coins corresponding to the price of the registered data will be transferred from the crypto asset account of the purchase requester to the crypto asset account of the holder. to add.

The output unit 135 notifies the registered data processing unit 132 of the registered data transfer instruction. The registered data processing unit 132 transfers ownership of the registered data from the holder's data management account to the purchase requester's data management account in accordance with the registered data transfer instruction output by the output unit 135. For example, the registered data processing unit 132 adds, to the blockchain, a transaction indicating that ownership of the registered data is transferred from the holder's data management account to the purchase requester's data management account. After this, the purchase requester becomes the new owner of the registered data, and the registered data purchased by the purchase requester can be purchased by a person different from the purchase requester using cryptographic assets.

Furthermore, when registered data is purchased, the output unit 135 outputs information for granting points or crypto assets that can be used in the area where the crypto assets used for purchase are available to the purchase requester. You can. Furthermore, when registered data is purchased, the output unit 135 outputs information for granting points or crypto assets that can be used in the area where the crypto assets used for purchase are available to the registrant. You can. The cryptographic asset given to the purchase requester or registrant is, for example, the cryptographic asset used to purchase registered data. The crypto assets given to the purchase requester or registrant are points different from crypto assets that can be used for settlement. Points, for example, are managed in a crypto asset account using blockchain, similar to crypto assets.

The output unit 135 calculates the value of the crypto assets or points to be given to the purchase requester or registrant so that, for example, the larger the price of the purchased registration data, the larger the value. For example, the output unit 135 adds, to the blockchain, a transaction indicating that the calculated value of the crypto asset or points will be added to the purchase requester's crypto asset account. Thereby, the management server 1 can provide crypto assets or points to the purchase requester in response to the purchase requester's purchase of registered data, thereby promoting the purchase of registered data by the purchase requester.

Further, the output unit 135 adds, for example, to the blockchain a transaction indicating that the calculated value of the crypto asset or points is to be added to the registrant's crypto asset account. Thereby, the management server 1 can provide cryptographic assets or points to the registrant in response to the purchase requester's purchase of the registered data, thereby promoting the registration and sale of the registered data by the registrant.

[Sequence of information processing method]
FIG. 7 is a sequence diagram of an exemplary information processing method executed by the information processing system S according to the present embodiment. The user terminal 2 used by the registrant transmits a registration request for registering registration data to the management server 1 in response to a predetermined operation performed by the registrant (S11).

In the management server 1, the registration unit 131 receives a registration request from the user terminal 2. The registration unit 131 registers the registration data by notifying the registration data processing unit 132 of information for associating the data ID and user ID indicated by the registration request and storing them in the storage device (S12). The registered data processing unit 132 grants ownership of the registered data to the registrant according to the information notified from the registration unit 131. As a result, the registrant becomes the holder of the registered data at the time the registered data is registered. When the ownership of registered data is transferred due to transfer or the like between users, the registered data processing unit 132 transfers the ownership of the registered data between users.

The reception unit 133 transmits the registration data information including the user ID of the registrant and the holder, the attribute information of the registrant, and the price of the registered data to the user terminal 2 used by the purchase requester ( S13). The user terminal 2 of the purchase requester displays the registered data information received from the management server 1 on the display unit.

In response to a predetermined operation performed by the purchase requester, the user terminal 2 of the purchase requester sends a purchase request to the management server 1 to purchase registered data held by the holder using crypto assets. Send (S14).

In the management server 1, the reception unit 133 receives a purchase request from the user terminal 2. The determination unit 134 acquires, for example, attribute information that is stored in advance in the storage unit 12 and indicates the attribute of the registrant of the registered data corresponding to the data ID indicated by the purchase request.

[Effects of embodiment]
According to the information processing system S according to the present embodiment, the management server 1 allows a purchase requester to receive registered data on the condition that the attributes of the registrant who has registered the registered data satisfy the conditions under which the crypto asset can be used. Make it available for purchase with crypto assets. As a result, the information processing system S can limit the use of cryptographic assets to the purchase of registered data registered by users with specific attributes, thereby activating economic circulation among users with specific attributes.

[Modified example]
In the above embodiment, it is determined whether the registered data can be purchased with crypto assets after the purchase requester makes a purchase request, whereas in this modification, the registration data is determined before the purchase requester makes the purchase request. It is determined whether the data can be purchased with crypto assets. Hereinafter, differences from the above-described embodiment will be mainly explained.

Before a purchase requester makes a purchase request, the determination unit 134 in the management server 1 acquires the user ID of the registrant and holder of the registered data based on information stored in the blockchain or database. Further, the determination unit 134 acquires the attribute information of the registrant of the registration data, which is stored in advance in the storage unit 12. Further, the determination unit 134 obtains the price of the registered data stored in the storage unit 12 in advance. When a plurality of pieces of registered data are registered in the blockchain or a database, the management server 1 performs subsequent processing for each piece of registered data.

The determining unit 134 determines, based on the relationship between the registrant's attributes indicated by the acquired attribute information and each of one or more crypto assets that can be used to purchase the registered data, whether the registered data can be purchased with the crypto assets. Determine whether or not. One or more cryptographic assets that can be used to purchase registered data are set in the information processing system S in advance.

The determination unit 134 obtains, for example, usage conditions that are stored in advance in the storage unit 12 and are conditions under which the cryptographic asset can be used. For example, the availability condition is such that at least one of the following is a predetermined value: the region associated with the registrant, the registrant's nationality, the registrant's age, the registrant's gender, and the registrant's qualifications. or within a predetermined range. The determination unit 134 determines that the registered data can be purchased with crypto assets if the attributes of the registrant indicated by the attribute information satisfy the acquired usage conditions, and if not, the determination unit 134 determines that the registered data can be purchased with crypto assets. It is determined that it is not available for purchase.

The reception unit 133 receives the registration data information including the user ID of the registrant and the holder, the attribute information of the registrant, and the price of the registered data, and the determination unit 134 receives the registration data for each of one or more crypto assets. It is transmitted to the user terminal 2 used by the purchase requester together with determination information indicating the determination result as to whether or not the purchase is possible. The user terminal 2 displays the registration data information and determination information received from the management server 1 on the display unit.

FIG. 8 is a schematic diagram of an exemplary screen displayed by the user terminal 2 in this modification. For example, based on the registered data information received from the management server 1, the user terminal 2 stores the contents of the registered data held by the holder, the user ID of the registrant and holder of the registered data, and the registrant's attribute information. , the price of the registered data, and are displayed on the display section.

Further, the user terminal 2, for example, based on the determination information received from the management server 1, determines whether the registered data can be purchased with each of one or more crypto assets that can be used to purchase the registered data. Display on the display. For example, depending on the determination result, the user terminal 2 makes it possible to specify cryptographic assets whose registered data is determined to be purchasable, and makes it impossible to specify cryptographic assets whose registered data is determined not to be purchasable.

The user terminal 2 accepts designation of a cryptographic asset to be used for purchasing registered data from among one or more cryptographic assets determined to be available for purchasing registered data. In response to a predetermined operation performed by a purchase requester, the user terminal 2 transmits a purchase request to the management server 1 to purchase registered data held by the holder using cryptographic assets. The purchase request is, for example, information indicating the user ID of the purchase requester, the data ID of the registered data to be purchased, and the cryptographic asset designated by the purchase requester.

In the management server 1, the reception unit 133 receives a purchase request from the user terminal 2. The determination unit 134 may determine again whether the registered data can be purchased with the cryptographic assets indicated by the purchase request, or may use the determination result obtained before the purchase requester makes the purchase request without re-determination. You can.

The output unit 135 issues a purchase request to a user who owns the crypto asset indicated by the purchase request, on the condition that the reception unit 133 receives the purchase request and the determination unit 134 determines that the registered data can be purchased with crypto assets. A crypto asset transfer instruction for changing the user who owns the registered data from the holder to the purchase requester is output.

According to the information processing system S according to this modification, it is possible to notify the purchase requester whether or not registered data can be purchased with crypto assets before the purchase requester makes a purchase request. It is possible to make it easier to select the crypto assets used for purchasing. Furthermore, as in the above-described embodiment, the information processing system S can limit the use of crypto assets to the purchase of registered data registered by users with specific attributes, thereby stimulating economic circulation among users with specific attributes. can be made into
