[0003] [Patent Document 1] JP 2023-72 A Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, users have been buying and selling tokens associated with content such as images and music. When a token is bought and sold between users, the user who purchased the token can obtain ownership of the content associated with the token, and the user who sold the token can receive payment. However, because whether or not a token is purchased depends on the content, there has been a problem in that tokens associated with unpopular content are difficult to purchase.

[0005] The present invention has been made in consideration of these points, and aims to facilitate the buying and selling of tokens associated with content. [Means for solving the problem]

[0008] The associating unit may associate the changed content, which is generated by executing a predetermined program that is associated in advance with the token, with the token.

[0009] The content acquisition unit may acquire the changed content generated on condition that the sales status indicates that the tokens have not been sold for a reference time or longer.

[0010] The content acquisition unit may acquire the changed content generated under the condition that the sales status indicates that a level of attention indicating a degree to which the token is receiving attention from a plurality of users is equal to or lower than a reference value.

[0011] The information processing device may further have a reception unit that receives from the holder of the token a specification of change conditions that are conditions for generating the changed content, and the content acquisition unit may acquire the changed content generated on the condition that the sales status satisfies the change conditions.

[0012] The information processing device may further have a reception unit that receives specification of change conditions, which are conditions for generating the changed content, from a sales manager who manages the sales of the token, and the content acquisition unit may acquire the changed content generated on the condition that the sales status satisfies the change conditions.

[0013] The content acquisition unit may generate an input sentence for causing a machine learning model to change the content, and acquire the content changed by inputting the generated input sentence into the machine learning model as the changed content.

[0014] The sales status acquisition unit may acquire information indicating the sales status of the token and other tokens different from the token, and the content acquisition unit may acquire the modified content generated by modifying the content based on the sales status of the token and the other tokens.

[0015] The content acquisition unit may acquire the modified content generated by modifying the content to incorporate elements of other content associated with the other token, on condition that the sales status indicates that the token has not been sold and the sales status indicates that the other token has been sold.

[Figure 7] FIG. 1 is a flowchart illustrating an exemplary information processing method executed by an information processing device according to an embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] [Outline of Information Processing System S] 1 is a schematic diagram of an information processing system S according to this embodiment. The information processing system S includes an information processing device 1, an information terminal 2, and a sales point server 3. The information processing system S may also include other devices such as servers and terminals.

[0021] The information processing device 1 is a computer that performs processing related to transactions of tokens managed on a blockchain. A token is information stored on a blockchain and is held by any user. A token can be bought and sold between users. A token is associated with content, which is digital data such as an image or music, and is information that indicates the ownership of the content. A token is, for example, an NFT (Non-Fungible Token).

[0022] The token is stored in association with user identification information (user ID: Identifier) ​​for identifying the user who is the holder, by a blockchain constructed in, for example, the storage unit of the information processing device 1 or in the storage unit of a device different from the information processing device 1. The blockchain includes multiple blocks of data, and each block includes one or more transactions indicating that the token has been transferred (that the holder of the token has been changed). Each block in the blockchain includes a hash value generated according to a predetermined rule, and the accuracy of the entire blockchain is guaranteed by checking the consistency of the hash values ​​between blocks.

[0023] The information terminal 2 is a computer used by a user. The user is, for example, a person or organization that buys and sells tokens managed on a blockchain. The information terminal 2 is, for example, a smartphone, a tablet terminal, a personal computer, or the like. The information terminal 2 has an operation unit such as a touch panel or a keyboard for accepting operations, and a display unit such as a liquid crystal display for displaying information. The information terminal 2 is capable of communicating with the information processing device 1 and the sales outlet server 3 via a network.

[0024] The sales office server 3 is a computer that performs processing for users to buy and sell tokens on the blockchain. The sales office server 3 allows other users to purchase tokens that a user is selling. In addition, when a token is bought and sold, the sales office server 3 transfers assets (cryptocurrency or legal tender) corresponding to the price of the token from the user who purchased the token to the user who sold the token. The sales office server 3 is managed by, for example, a business operator that provides a sales office (platform) for buying and selling tokens or a predetermined sales manager of a store that opens a store on the platform. The sales office server 3 is capable of communicating with the information processing device 1 and the information terminal 2 via a network.

[0025] An overview of the processing executed by the information processing system S according to this embodiment will be described below. The information processing device 1 outputs information for selling a token held by a user and associated with content. The sales server 3 sells the token associated with content according to the information output by the information processing device 1.

[0026] When a user other than the user wishes to purchase a token associated with content, the sales office server 3 transfers the token from the user to the other user in exchange for assets corresponding to the price of the token. When no other user wishes to purchase the token, the sales office server 3 continues selling the token.

[0027] The information processing device 1 acquires information indicating a sales status of a token associated with content. The information processing device 1 acquires changed content generated by changing the content associated with the token based on the sales status. For example, the information processing device 1 inputs content into a predetermined machine learning model stored in advance in the information processing device 1 or another device, and acquires the content output by the machine learning model as changed content.

[0028] The information processing device 1 associates the changed content with a token held by the user, and outputs information for selling the token associated with the changed content. The sales server 3 sells the token associated with the changed content according to the information output by the information processing device 1.

[0029] In this way, the information processing system S changes the content based on the sales status of the token associated with the content, and outputs information for selling the token associated with the changed content. In this way, the information processing system S can promote buying and selling of tokens by dynamically changing the content associated with the tokens on sale according to the sales status.

[0030] [Configuration of Information Processing System S] FIG. 2 is a block diagram of an 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 indicates a configuration in functional units, not a configuration in hardware (device) units. Therefore, the blocks shown in FIG. 2 may be implemented in a single device, or may be implemented separately in multiple devices. Data may be exchanged between blocks via any means, such as a data bus, a network, or a portable storage medium.

[0031] The information processing device 1 includes a communication unit 11, a storage unit 12, and a control unit 13. The information processing device 1 may be configured by connecting two or more physically separate devices by wire or wirelessly. The information processing device 1 may also be configured by a cloud that is a collection of computer resources.

[0032] The communication unit 11 has a communication controller for transmitting and receiving data between the information terminal 2 and the sales server 3 via the network. The communication unit 11 notifies the control unit 13 of data received from the information terminal 2 and the sales server 3 via the network. The communication unit 11 also transmits data output from the control unit 13 to the information terminal 2 and the sales server 3 via the network.

[0033] The storage unit 12 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk drive, etc. The storage unit 12 stores in advance a program to be executed by the control unit 13. The storage unit 12 may be provided outside the information processing device 1, in which case data may be exchanged between the storage unit 12 and the control unit 13 via a network.

[0034] The control unit 13 has a content acquisition unit 131, an association unit 132, an output unit 133, a reception unit 134, a sales status acquisition unit 135, and a generation unit 136. The control unit 13 is a processor such as a CPU (Central Processing Unit), and functions as the content acquisition unit 131, the association unit 132, the output unit 133, the reception unit 134, the sales status acquisition unit 135, and the generation unit 136 by executing a program stored in the storage unit 12.

[0035] Hereinafter, a detailed description will be given of the processing executed by the information processing system S. First, a description will be given of the processing in which the information processing device 1 sells a token associated with content. Fig. 3 is a schematic diagram for explaining the processing in which the information processing device 1 sells a token.

[0036] The content acquisition unit 131 acquires information indicating content that the user wishes to sell. The content acquisition unit 131 acquires information indicating content, which is digital data specified by the user, from, for example, the storage unit 12 or another device different from the information processing device 1. The content is pre-stored in a predetermined storage device. The content is, for example, an image, which is a two-dimensional or three-dimensional still image or a moving image. The content may be sound, such as music, voice, or sound effects. The content may be a character or an item in a game.

[0037] The associating unit 132 associates the content indicated by the information acquired by the content acquiring unit 131 with a token managed on the blockchain. The associating unit 132 generates, for example, a token associated with the content. The token is associated with the content by, for example, including access information such as a uniform resource identifier (URI) for accessing the content stored in a predetermined storage device, or including the content itself.

[0038] The associating unit 132 adds a transaction indicating a token associated with the content, a token ID for identifying the token, and a user ID for identifying the user who holds the token to the blockchain. In this way, the associating unit 132 records a token with the user as the holder in the blockchain. The associating unit 132 may also associate the user ID and the content with a token already recorded on the blockchain, rather than with a newly generated token.

[0039] The output unit 133 outputs sales information for selling the token associated with the content at a predetermined sales outlet. The sales outlet is, for example, a platform such as a website for buying and selling tokens between users. The output unit 133 transmits, for example, sales information for starting the sale of the token to the sales outlet server 3. The sales information is, for example, information that associates the token ID of the token to be sold with the user ID of the user.

[0040] The sales office server 3 starts selling tokens at a predetermined price on the blockchain in accordance with the sales information received from the information processing device 1. The price at which the tokens are sold may be specified by the user or may be automatically determined by the output unit 133 or the sales office server 3. When a user other than the user wishes to purchase a token associated with content, the sales office server 3 transfers assets corresponding to the price of the token from the other user to the user and transfers the token from the user to the other user. When none of the other users wishes to purchase the token, the sales office server 3 continues selling the token.

[0041] Next, a process of accepting change conditions for changing content by the information processing device 1 will be described. The accepting unit 134 displays a acceptance screen for accepting change conditions on the information terminal 2 used by a user who is a holder of a token or a sales manager who manages the sale of tokens. The accepting unit 134 accepts the change conditions before the start of the sale of tokens, or accepts the change conditions after the start of the sale of tokens.

[0042] 4 is a schematic diagram of the information terminal 2 displaying an exemplary reception screen. The reception screen includes an area for receiving designation of change conditions from a token holder or a sales manager. The change conditions include, for example, changing the content based on the time during which the token has not been sold, or changing the content based on the attention level of the token. The information terminal 2 transmits the change conditions designated on the reception screen to the information processing device 1. The reception unit 134, for example, receives the change conditions indicated by the information transmitted by the information terminal 2, and stores the received change conditions in the storage unit 12.

[0043] Next, a process in which the information processing device 1 acquires information indicating the sales status of content will be described. The sales status acquisition unit 135 acquires sales status information indicating the sales status of tokens associated with content that the user wishes to sell from the storage unit 12 or another device (e.g., the sales outlet server 3) different from the information processing device 1 at a predetermined timing (daily, weekly, etc.). The sales status acquisition unit 135 may also acquire sales status indicating the sales status of the token associated with the content that the user wishes to sell and other tokens different from the token. The token associated with the content that the user wishes to sell is, for example, a token held by the user who specified the above-mentioned change condition. The other token is a token held by another user different from the user and associated with a predetermined content.

[0044] 5 is a schematic diagram for explaining the sales status of a token. The sales status includes, for example, whether the token is on sale (whether it has been purchased), the current or end-of-sale price of the token, and the sales period. The sales period is represented, for example, by the dates of the start and end of the sale.

[0045] The sales status may include a degree of attention that indicates the degree to which the token is attracting attention from multiple users. The degree of attention is represented, for example, by at least one of the number of accesses, which is the number of users who viewed the information on the token or content, and the number of favorites, which is the number of operations performed by users that indicate that they like the token or content. The sales status is not limited to the specific information shown here, and may include other information regarding the sale of the token.

[0046] Next, a process in which the information processing device 1 changes and sells content will be described. Fig. 6 is a schematic diagram for explaining a process in which the information processing device 1 sells a token associated with changed content.

[0047] At a predetermined timing, the content acquisition unit 131 judges whether or not the sales status indicated by the sales status information acquired by the sales status acquisition unit 135 satisfies a change condition. The change condition is, for example, a condition accepted by the acceptance unit 134 from a token holder or a sales manager, or a condition preset in the memory unit 12. The timing for judging the change condition is, for example, the point in time when a predetermined time (one day, one week, one month, etc.) has elapsed since the start of the token sales.

[0048] When the change condition includes changing the content based on the time during which the token has not been sold, the content acquisition unit 131 determines that the sales status satisfies the change condition on the condition that the sales status indicates that the token has not been sold for a reference time or more (for example, that a reference time or more has passed since the start of sales). On the other hand, the content acquisition unit 131 determines that the sales status does not satisfy the change condition on the condition that the sales status does not indicate that the token has not been sold for a reference time or more. The reference time is specified by the token holder or sales manager, or is preset in the memory unit 12. This allows the information processing system S to change the content associated with a token that has not been sold for a long time, and promote buying and selling of tokens.

[0049] When the change condition includes changing the content based on the attention level of the token, the content acquisition unit 131 determines that the sales status satisfies the change condition on the condition that the sales status indicates that the attention level is equal to or lower than a reference value (for example, the number of accesses or the number of favorites is equal to or lower than a reference value). On the other hand, the content acquisition unit 131 determines that the sales status does not satisfy the change condition on the condition that the sales status does not indicate that the attention level is equal to or lower than a reference value. The reference value is specified by the token holder or sales manager, or is preset in the memory unit 12. This allows the information processing system S to change the content associated with a token with low attention level, and promote buying and selling of tokens.

[0050] The content acquisition unit 131 acquires the changed content generated by changing the content associated with the token held by the user, on condition that the sales status is determined to satisfy the change condition. The changed content is generated, for example, by the information processing device 1 or another device different from the information processing device 1 executing a predetermined program.

[0051] The content acquisition unit 131 generates, for example, an input sentence (also called a command sentence or a prompt) for causing a machine learning model, which is a program for changing the content, to change the content. The machine learning model in this embodiment is generated in advance by machine learning a large amount of digital data using a known deep learning process such as DNN (Deep Neural Network). The machine learning model receives digital data such as an image or music and an input sentence, and outputs digital data changed according to the input sentence. The machine learning model is stored in advance in the storage unit 12 or another device.

[0052] The content acquisition unit 131 generates, for example, an input sentence indicating to change the color, orientation, pattern, etc. of content that is an image, or an input sentence indicating to change the lyrics, melody, voice, etc. of content that is music, using rules (templates, etc.) pre-stored in the memory unit 12.

[0053] The content acquisition unit 131 may generate an input sentence for causing the machine learning model to change the content based on the sales status indicated by the sales status information acquired by the sales status acquisition unit 135. For example, the content acquisition unit 131 generates an input sentence so that the extent to which the content is changed increases as the time elapsed from the start of sales indicated by the token sales status increases, and the extent to which the content is changed decreases as the time elapsed from the start of sales indicated by the token sales status decreases. This allows the information processing system S to flexibly switch the changes to the content according to the token sales status.

[0054] Furthermore, the content acquisition unit 131 may generate an input sentence for causing the machine learning model to change the content based on the sales status of the token and other tokens different from the token. For example, the content acquisition unit 131 generates an input sentence so as to incorporate elements of other content associated with the other token (color, orientation, etc. of an image, or lyrics, melody, etc. of music) into the content, on the condition that the sales status indicates that the token is not selling and the sales status indicates that the other token has been sold. In this way, the information processing system S can make it easier for the token to be purchased by changing the content to incorporate elements of other content that is selling well.

[0055] When the information processing device 1 executes a program for changing content, the generation unit 136 acquires the content acquired by the content acquisition unit 131, the input sentence generated by the content acquisition unit 131, and the machine learning model pre-stored in the storage unit 12. The generation unit 136 inputs the acquired content and the input sentence to the machine learning model, thereby generating digital data using the machine learning model. The content acquisition unit 131 acquires the digital data generated by the generation unit 136 as changed content.

[0056] When a program for changing the content is executed by another device different from the information processing device 1, the content acquisition unit 131 transmits the acquired content and the generated input sentence to the other device. The other device inputs the content and the input sentence transmitted by the information processing device 1 to a machine learning model, generates digital data using the machine learning model, and transmits the generated digital data to the information processing device 1. The content acquisition unit 131 acquires the digital data transmitted by the other device as changed content.

[0057] The associating unit 132 associates the changed content acquired by the content acquiring unit 131 with the token that was associated with the content before the change. The associating unit 132 associates the changed content with the token by changing the content stored in a predetermined storage device or by changing the contents of the token.

[0058] When changing the content stored in the storage device, the associating unit 132 replaces the pre-change content with the post-change content acquired by the content acquisition unit 131 in the storage device.

[0059] When changing the contents of the token, the associating unit 132 adds to the blockchain a transaction for changing access information (such as a URI) for accessing the pre-change content included in the token to access information for accessing the post-change content. As an alternative method, the associating unit 132 may add to the blockchain a transaction for changing the pre-change content included in the token to the post-change content.

[0060] This allows the information processing system S to dynamically change the content associated with the tokens on sale according to the sales status, thereby promoting the buying and selling of tokens.

[0061] The associating unit 132 may associate the changed content generated by executing a predetermined program that is previously associated with the token on the blockchain with the token. In this case, the associating unit 132 previously associates the token associated with the content with a program (e.g., a smart contract) for changing the content on the blockchain.

[0062] The program associated with the token changes the content associated with the token, for example, on the condition that the token has not been sold for a reference time or longer (the holder has not changed). The manner in which the content is changed is the same as when the program is executed by the information processing device 1 or other devices. The program associated with the token associates the changed content with the token that was associated with the content before the change. This allows the information processing system S to dynamically change the content associated with the token using the program associated with the token.

[0063] The output unit 133 outputs sales information for selling the token associated with the changed content at a predetermined sales outlet. For example, the output unit 133 transmits sales information for starting the sale of the token to the sales outlet server 3. The sales information is, for example, information that associates the token ID of the token to be sold with the user ID of the user.

[0064] The sales server 3 starts selling tokens at a predetermined price on the blockchain in accordance with the sales information received from the information processing device 1. The price at which the tokens are sold may be the same as the price before the content was changed, or may be a price lower than the price before the content was changed.

[0065] [Information processing method flow] 7 is a diagram showing a flowchart of an exemplary information processing method executed by the information processing device 1 according to the present embodiment. The content acquisition unit 131 acquires information indicating the content that the user wishes to sell. The association unit 132 associates the content indicated by the information acquired by the content acquisition unit 131 with a token managed on the blockchain (S11). The output unit 133 outputs sales information for selling the token associated with the content at a predetermined sales outlet (S12).

[0066] At a predetermined timing, the sales status acquisition unit 135 acquires sales status information indicating the sales status of the token associated with the content that the user wishes to sell from the memory unit 12 or another device other than the information processing device 1 (S13).

[0067] At a predetermined timing, the content acquisition unit 131 determines whether or not the sales status indicated by the sales status information acquired by the sales status acquisition unit 135 satisfies the change condition (S14). If the content acquisition unit 131 determines that the sales status does not satisfy the change condition (NO in S15), the information processing device 1 repeats steps S13 to S14.

[0068] When the content acquisition unit 131 determines that the sales status satisfies the change condition (YES in S15), the content acquisition unit 131 acquires changed content generated by changing the content associated with the token held by the user (S16). The association unit 132 associates the changed content acquired by the content acquisition unit 131 with the token associated with the content before the change (S17). The output unit 133 outputs sales information for selling the token associated with the changed content at a specified sales outlet (S18).

[0069] [Effects of the embodiment] According to the information processing system S of this embodiment, the information processing device 1 changes the content based on the sales status of the token associated with the content, and outputs information for selling the token associated with the changed content. In this way, the information processing system S can promote buying and selling of tokens by dynamically changing the content associated with the tokens on sale according to the sales status.

[0070] Furthermore, this invention will make it possible to contribute to Goal 9 of the United Nations' Sustainable Development Goals (SDGs), which is to "build resilient infrastructure, promote industry, innovation and infrastructure."

For example, all or part of the device can be configured by distributing or integrating functionally or physically in any unit.
