[0003] [Patent Document 1] Japanese Patent Publication No. 2023-72 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 sold between users, the user who purchases the token can acquire ownership of the content associated with the token, and the user who sells 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]

[0006] An information processing device of a first aspect of the present invention includes a sales status acquisition unit that acquires information indicating the sales status of a token associated with content, a content acquisition unit that acquires modified content generated by modifying the content associated with the token based on the sales status, an association unit that associates the modified content with the token, and an output unit that outputs information for selling the token associated with the modified content.

[0007] The information processing device may further have a generation unit that generates the modified content by executing a predetermined program on the content, and the association unit may associate the modified content generated by the generation unit with the token.

[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 the 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 on the condition that the sales status indicates that the level of attention, which indicates the degree to which the token is attracting attention from multiple users, is below 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 sale 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 that the sales status indicates that the other token has been sold.

[0016] An information processing method of a second aspect of the present invention includes the steps of: acquiring information indicating the sales status of a token associated with content; acquiring modified content generated by modifying the content associated with the token based on the sales status; associating the modified content with the token; and outputting information for selling the token associated with the modified content, executed by a processor.

[0017] A third aspect of the program of the present invention causes a processor to execute the steps of acquiring information indicating the sales status of a token associated with content, acquiring modified content generated by modifying the content associated with the token based on the sales status, associating the modified content with the token, and outputting information for selling the token associated with the modified content.

DETAILED DESCRIPTION OF THE INVENTION

[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 outlet 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 held by one of the users. A token can be bought and sold between users. A token is associated with content, such as digital data such as images 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 token holder 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, or a personal computer. The information terminal 2 has an operation unit such as a touch panel or keyboard for accepting operations, and a display unit such as a liquid crystal display for displaying information. The information terminal 2 can communicate 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. Furthermore, when a token is bought or sold, the sales office server 3 transfers assets (crypto assets 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, for example, by a business operator that provides a sales office (platform) for buying and selling tokens or a designated sales manager of a store or the like that operates 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 tokens held by a user and associated with content. The sales outlet server 3 sells the tokens associated with content in accordance with the information output by the information processing device 1.

[0026] If another 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. If 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 the sales status of tokens 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, as the changed content, content output by the machine learning model.

[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 outlet server 3 sells the token associated with the changed content in accordance with 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 tokens associated with the content, and outputs information for selling the tokens 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 also exist. In FIG. 2, each block indicates a functional configuration rather than a hardware (device) configuration. 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 via wired or wireless connections. The information processing device 1 may also be configured by a cloud, which 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 outlet 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 outlet 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 outlet 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 programs 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] The following describes in detail the processing executed by the information processing system S. First, a description will be given of the processing by which the information processing device 1 sells tokens associated with content. Fig. 3 is a schematic diagram for explaining the processing by which the information processing device 1 sells tokens.

[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, such as a two-dimensional or three-dimensional still image or a moving image. The content may be music, voice, sound effects, or other sounds. The content may also be a character or 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 by including the content itself.

[0038] The associating unit 132 adds to the blockchain 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. In this way, the associating unit 132 records in the blockchain a token whose holder is the user. The associating unit 132 may also associate the user ID and 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 tokens associated with 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 tokens 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 also 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 will be described in which the information processing device 1 accepts change conditions for changing content. The accepting unit 134 displays a acceptance screen for accepting change conditions on the information terminal 2 used by a user who is a token holder or a sales manager who manages token sales. The accepting unit 134 accepts the change conditions before token sales begin, or accepts the change conditions after token sales begin.

[0042] 4 is a schematic diagram of the information terminal 2 displaying an exemplary reception screen. The reception screen includes an area for receiving specification of change conditions from a token holder or sales manager. The change conditions include, for example, changing the content based on the time period during which tokens have not been sold, or changing the content based on the attention level of the token. The information terminal 2 transmits the change conditions specified 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., 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 tokens associated with content that the user wishes to sell and other tokens different from the tokens. The tokens associated with content that the user wishes to sell are, for example, tokens held by the user who specified the above-mentioned change conditions. The other tokens are tokens held by other users different from the user and associated with specified content.

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

[0045] The sales status may include a degree of attention indicating 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 have viewed the token or content information, and the number of favorites, which is the number of operations performed by users indicating that they like the token or content. The sales status is not limited to the specific information shown here, and may include other information related to the sale of tokens.

[0046] Next, a description will be given of the process in which the information processing device 1 modifies and sells content. Fig. 6 is a schematic diagram for explaining the process in which the information processing device 1 sells tokens associated with modified content.

[0047] At a predetermined timing, the content acquisition unit 131 determines whether 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 received by the reception unit 134 from the token holder or the sales manager, or a condition set in advance in the storage unit 12. The timing for determining the change condition is, for example, when a predetermined time (one day, one week, one month, etc.) has elapsed since the start of token sales.

[0048] When the change condition includes changing the content based on the time period 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 longer (for example, that a reference time or longer has elapsed 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 longer. The reference time is specified by the token holder or sales manager, or is set in advance in the storage 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, thereby promoting the 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 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 set in advance in the storage unit 12. This allows the information processing system S to change the content associated with tokens with low attention levels, thereby promoting the 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 the 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 referred to as a command sentence or a prompt) for causing a machine learning model, which is a program for changing 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, for example, 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 in accordance with 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 the input sentence so that the extent to which the content is changed increases the longer the elapsed time from the start of sales indicated by the token sales status, and the extent to which the content is changed decreases the shorter the elapsed time from the start of sales indicated by the token sales status. This allows the information processing system S to flexibly switch the content changes depending on the token sales status.

[0054] Furthermore, the content acquisition unit 131 may generate an input statement to cause the machine learning model to change the content based on the sales status of the token and other tokens different from the token in question. For example, on the condition that the sales status indicates that the token is not selling and that the other tokens have been sold, the content acquisition unit 131 generates an input statement to incorporate elements of other content associated with the other tokens (such as the color or orientation of an image or the lyrics or melody of music) into the content. In this way, the information processing system S can make it easier for tokens to be purchased by modifying 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 a machine learning model pre-stored in the storage unit 12. The generation unit 136 inputs the acquired content and input sentence into 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 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 input sentence transmitted by the information processing device 1 into 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 acquiring unit 131 in the storage device.

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

[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 modified content generated by executing a predetermined program pre-associated with the token on the blockchain with the token. In this case, the associating unit 132 pre-associates the token associated with the content with a program (e.g., a smart contract) for modifying 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 a 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 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 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 this embodiment. The content acquisition unit 131 acquires information indicating content that a 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 tokens 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 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] If 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 that was 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 predetermined 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 "Build resilient infrastructure, promote inclusive and sustainable industrialization, and promote innovation and resilience."

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