Description

The present invention relates to a digital content transaction management system and transaction management method using non-fungible tokens (NFT) and blockchain.

Digital content, especially entertainment works such as games, movies, dramas, variety shows, music, novels, manga, photographs, illustrations, photos and costumes of cosplayers, is used to create entertainment digital content, which is content created in digital format. requires sense and talent.

However, digital content is easy to copy and falsify, so even if it is a work that is evaluated as having originality, it cannot be considered as having asset value as it is. Furthermore, even if a work is not currently evaluated but is expected to have an enormous asset value in the future as the years pass, it is not considered to have an asset value that can be invested in as it is.

Therefore, by linking and registering digital content and non-fungible tokens (also called NFTs) that contain identification information that is practically impossible to falsify, on a blockchain network that is built on top of the Internet. , digital content can be bought and sold on a marketplace on the blockchain network, as it is difficult to prove false information, it is difficult to prove the value of an irreplaceable asset that can be treated as a unique entity, and ownership can be proven. Technologies that make it possible to publish information are attracting attention.

JP2021-72116A

Digital content that has uniqueness or is not valued at the moment, but will likely be valued highly in the years to come, can be owned exclusively as a one-of-a-kind item, creating an economy where the property value can be maximized. A system is necessary.

In the system of Patent Document 1, digital content linked to NFTs on a blockchain network has asset value, but the separate handling of ownership and usage rights is unclear, so homogenized ownership that indicates ownership is used. Generates a right token, and based on this ownership token, generates a non-exclusive right to use token indicating the right to use the non-homogenized asset, and when the right to use token is transferred, the profit distribution amount is sent to the owner. It is proposed that the property be used to

According to the system disclosed in Patent Document 1, since the author who has the ownership token can use the usage right token non-exclusively for a service provided separately, there are the following disadvantages. Specifically, it is a game that is applied to TVs, PCs, DVDs, game consoles, smartphones, etc., in which many characters appear and engage in battles and adventures, in which multiple participants (players) act as avatars. For games where the game is developed by manipulating characters, if the right to use the same character is granted to multiple people over and over again, multiple rights holders will be able to operate the same character in the game, which is a serious problem. Since this would cause inconvenience, it is not possible to grant usage rights tokens to the characters, the form of use of property value is limited, and the economic value attached to the characters remains low. Furthermore, the economic benefit that accrues to the author is limited to the number of usage rights granted.

The inventors believe that if the following mechanism is provided, the property value of games will be enormous, it will be easier for authors to raise funds, it will be easier to develop games, and it will contribute to the creation of digital content. I came up with the idea that it would be.

In other words, when it comes to games in which the characters mentioned above appear, as well as other games, the more the game becomes a big hit, the more likely the player is to own ownership of a specific character (not limited to an animated object) that appears in that game. It is hoped that there will be a system in which such claims can be treated as something that can be claimed. Therefore, if we create a mechanism where individual characters that appear in the game are sold on the marketplace, you can select your favorite character on a first-come-first-served basis and acquire ownership of a specific character, especially the design of a cosplayer. After that, if there is an auction sale method for selling the ownership of your favorite character on the marketplace, you can easily buy and sell it, and as you repeatedly buy and sell ownership, you will receive a certain amount of profit from the sale. A mechanism will be established in which a percentage of points (economic value) will go to the author or those who have previously relinquished ownership.

On the other hand, if all digital content is released on an Internet marketplace, there will be no originality, there will be no desire to purchase it, or there will be no increase in future value even after many years have passed since purchase. This would lead to the deterioration of the marketplace's publishing function by publishing works that are not intended to be sold at all, so while digital content is constantly being solicited, each piece of digital content must be reviewed and selected one by one. It is necessary to provide a mechanism for publishing on

Therefore, the present invention was devised in view of the above-mentioned points, and it examines and selects digital content that is a mixture of cobblestones, links non-fungible tokens to useful digital content on the blockchain, assigns asset value, and markets it. Digital content that can be published on a place and the ownership rights related to it can be bought and sold repeatedly after that, and a certain percentage of the sales profits from each sale go to the author and the person who relinquished the ownership rights.

Hereinafter, a digital content transaction management system 100 and a transaction management method according to an embodiment of the present invention will be described using FIG. 1.

In the current situation where digital content that is easy to copy generally has no property value, there is a need for protection for works that are considered to be original and highly evaluated, and the present invention It was devised from the perspective of recognizing the property value of digital content and giving it ownership rights to protect it.

In addition, the present invention provides a platform for linking NFTs to excellent digital content, regardless of whether the creator is famous or anonymous, recognizing the property value, registering ownership, and further providing a place to buy and sell digital content on the Internet. It protects the Furthermore, although the author (creator) of the present invention is anonymous and his work is currently undervalued or of no interest, if the author's fame increases in the future, his past works will be reconsidered and his evaluation will increase. If expected, it will also protect anonymous digital content and provide a mechanism to support startups by anonymous authors. Ownership here is proof of who owns the registered digital content with NFT, and rights can be bought and sold, and the use of digital content without NFT that is equivalent to digital content with NFT is permitted. NFT-attached digital content cannot be duplicated because it is NFT-attached.

[Embodiment of digital content transaction management system 100]
The communication network 1 is constructed by the Internet, a mobile communication network, a LAN, or the like. Furthermore, the communication network 1 may include not only wired communication but also wireless communication networks such as mobile communication systems (4G, 5G, 6G), Wi-Fi (registered trademark), WiMAX (registered trademark), etc. good.

The plurality of nodes 3a to 3e can communicate via the communication network 1, and can also perform P2P (Peer to Peer) communication in which they directly communicate with themselves and all other nodes on a one-to-one basis. A distributed network 2 is constructed on network 1.

Each of the plurality of nodes 3a to 3e has a data storage structure based on the blockchain 12.

In this embodiment, the blockchain 12 employs a private chain (or may be a private chain), and includes a Byzantine failure using an electronic signature, a hash pointer, and a data structure that uses a consensus algorithm and is easy to detect tampering. A plurality of nodes 3a to 3e participate in the network through P2P communication, and each node has a data storage function that autonomously continues to copy the transaction history of all the nodes. As a result, the distributed network 2 has the property that even if one node goes down, the other nodes 3a to 3e continue to maintain the entire system.

The blockchain 12 of this embodiment generates an origin block, and converts digital content and author information, etc., which are the result of an initial transaction contract (ownership registration), into this origin block using a hash function, and returns a hash value. , and then generates a second block that is hashed to the origin block by giving it a nonce value, and in this second block is assigned the transferor that is the result of the second transaction contract (ownership transfer registration). This is a function that converts and stores the transaction contents and nonce value, including the information of the transferee and the transferee information, using a hash function, and in this way generates the third and subsequent blocks one after another and stores the transaction contents.

A digital content transaction management system 100 according to an embodiment of the present invention includes a plurality of nodes 3a to 3e that constitute a distributed network 2 overlaid on a communication network 1, and has a market in a metaverse (virtual space) of the distributed network 2. Place 4 has been opened.

The marketplace 4 includes three functional units: an ownership registration unit 4a stored by the blockchain 12, a digital content publishing unit 4b, and a sales contract unit 4c. FIG. 2 shows a dedicated viewer that is a digital content publishing unit.

For the marketplace 4, the management institution 5 owns an examination communication device 6 for receiving and examining applications for procedures for establishing ownership of digital content, and an ownership registration unit 4a for recording digital contents that have passed the examination. It is equipped with a management communication device 7 that notifies the registration instructions.

Depending on the genre, the digital content created by the author may have excellent original expression that can be separated into multiple parts. In such cases, the author should apply for each part of the digital content separately. be able to. When an author applies for part of digital content, the subject of examination is the part related to the application, and the subject of registration by the ownership registration unit 4a is also the part related to the digital content that has been examined.

Note that the examination communication device 6 and the management communication device 7 are either a communication server owned by the management institution 5 connected to the communication network 1 that serves as both, or a separate communication device connected to the same communication server. Or it may be a separate PC.

The blockchain 12 configured in each of the plurality of nodes 3a to 3e stores the data of the ownership registration section 4a. In the ownership registration section 4a, the data is multiplied by a hash function and is recorded as data that is almost impossible to tamper with. In addition, in the ownership registration unit 4a, an unalterable NFT is linked to the digital content as a means of proving that it is unique.

The communication terminal 8 is used by the author A of the digital content to communicate with the review communication device 6 to apply for setting ownership of the digital content, and the viewers B, C, and D set the ownership in the marketplace 4. The communication terminals 9, 10, and 11 for communicating with the marketplace 4 in order to view the digital content published in the digital content publishing unit (dedicated viewer) 4b constitute essential components of the transaction management system 100 of the present invention. do not. Note that the communication terminal 8 is a PC that can be connected to the Internet, and the communication terminals 9, 10, and 11 are PCs or smartphones that can be connected to the Internet. This will be explained in detail below.

[Examination communication device 6]
In this transaction management system 100, an application 13 to the examination communication device 6 managed by the management institution 5 is required in order for the author of the digital content to be registered for ownership. The examination communication device 6 is, for example, a communication server connected to the Internet and managed by the management institution 5, or one or more PCs connected to this communication server.

[Application 13 to the examination communication device 6]
One method of applying 13 to the screening communication device 6 is to participate in an audition held by the management organization 5 using the screening communication device 6 as the application window. In order to participate in the audition, the author (applicant) of the digital content uses the communication terminal 8 that he or she manages to first communicate with the examination communication device 6 to complete membership registration and obtain a member ID. Using this member ID, the applicant pays the application fee (by bank transfer as described below) and sends the digital content, applicant data, and application for participation in the audition to the application reception desk of the examination communication device 6 using the communication terminal 8. Application 13 is made by doing so.

Other methods of application 13 to the examination communication device 6 include, for example, a method of constantly soliciting ghosts and monsters from the public based on manga character designs, local legends, or completely original creations, and a contest at a design school. We will also accept works submitted in . The works related to Application 13 include handwritten works that are not digital content. In the case of handwritten works, it is sufficient to process them to become digital content after receiving application 13.

In the application 13 to the examination communication device 6, the identification of the author (applicant) will be clearly specified, but the content related to the application 13 is digital content or content before digital processing, and as mentioned above, for example. If it falls under the category of a derivative work that is a redesign of a primary work under copyright law, such as a manga character design, a ghost, or a monster, it must be created with the consent of the author of the primary work. The derivative work may be the subject of Application 13.

If the digital content or the content before digital processing related to the application 13 to the examination communication device 6 is a derivative work, the author A in FIG. 1 is the person who created the derivative work. , In Application 13, it is necessary not only to specify the author A, but also to specify the creator of the digital content or the content before digital processing.

[Examination using the examination communication device 6]
When the author A sends an application 13 to the communication device for review 6 via the communication terminal 8 to register the ownership of the digital content, the person in charge of the review at the management agency 5 sends the display review unit 6a of the communication device for review 6 to the review communication device 6. The digital content that has been applied for is displayed, and the digital content is examined for permission or disapproval for ownership registration.

Prior to application 13 to the communication device for examination 6, there is a preliminary examination to select excellent works for primary works (draft works) under copyright law, such as manga character designs, ghosts, and monsters. are not applicable to the review here. If there is an application 13 for a primary copyrighted work, it will be subject to examination by the examination communication device 6, but if the primary copyrighted work is handwritten, it will be digitally processed.

For example, if each of the four works selected in this first round of screening is simplified or less sophisticated as a character design, a second one may be redesigned by an excellent designer other than the author of the first work. It is necessary to create a secondary work and file application 13 for this secondary work. This secondary work application 13 is subject to examination by the examination communication device 6. Furthermore, if a person other than the person in charge of the review of the management organization 5 conducts the review prior to the application 13 for the redesigned secondary work, the review may be conducted in advance using the communication device 6 for review.

This review does not compare the digital content to be reviewed with other digital content to judge the merits or inferiorities of the application, but rather if the digital content to be reviewed is original and is considered to be highly evaluated, If the author is unknown and the work is currently poorly evaluated or there is no interest in it, but if the author's reputation increases in the future, past works will be reviewed and evaluated, then the decision to approve. I do.

When issuing a determination of permission for registration as a result of the examination, the person in charge of the examination sends a notification of the determination of permission for registration to the communication terminal 8 of author A by e-mail to the applicant's e-mail address using the judgment notification unit 6b. Send 14.

Author A receives the notification 14 of the determination of registration permission on the communication terminal 8, and the registration fee is transferred 15 from the author A's financial institution account to the financial institution account of the management institution 5 via the communication terminal 8. It will be done. The reviewer outputs a registration instruction 16 including the digital content, content ID, author A's data, and author's member ID from the judgment notification unit 6b of the review communication device 6 to the communication unit 7a of the management communication device 7. do.

The management communication device 7 includes three functional units: a communication unit 7a, a recording unit 7b, and an accounting processing unit 7c.

When the communication unit 7a receives the registration instruction 16 from the judgment notification unit 6b, it transmits a registration instruction notification 17 to the ownership registration unit 4a of the marketplace 4 of the distributed network 2. The recording unit 7b stores digital content, content ID, author data, and author member ID in a database. If the digital content is a character such as a manga, and is a derivative work that is a redesign of the primary work, the author shall be responsible for the original copyright work as well as the author of the secondary work. The author shall be included as the creator. This author data may include the date of application to the examination communication device 6. This application date may be considered the ownership registration date, but the application date does not affect registration.

The accounting processing unit 7c manages a predetermined account of the management institution 5, a predetermined account of the author related to ownership registration, and a predetermined account of the former owner and new owner associated with the transfer of ownership. , processes and manages remittances between accounts necessary for the activities of the management institution 5.

Specifically, the management of application fees and registration fees paid by copyright holders to the management agency 5 (receipts and expenditures for activities), and the amount of current ownership sales and previous ownerships associated with ownership sales. The difference between the purchase and sale price of the right is calculated as profit, a part of the calculated profit is distributed as a distribution to the management institution 5, and the voters other than the previous owner and the new owner, and the calculated profit is used as distribution. The amount after deducting the distribution will be remitted to the new owners as the net profit from the sale. It is preferable that these processes, including remittance processing, be handled by a smart contract, which will be described later.

[Multiple nodes 3a to 3e and marketplace 4]
A plurality of nodes 3a to 3e have opened a marketplace 4 in a metaverse (virtual space) on the distributed network 2. The marketplace 4 has functional units related to digital content, such as an ownership registration unit 4a, a digital content publishing unit 4b, and a sales contract unit 4c, and users can click on any of the three selection buttons provided on the top page of the homepage. This allows access to each functional section of the ownership registration section 4a, the digital content publishing section 4b, or the sales contract section 4c.

The ownership registration unit 4a and the sales contract unit 4c of the marketplace 4 automatically create contracts (transactions) related to all trading activities when the transaction contract and its performance conditions are set in advance and the performance conditions are met. It is equipped with a smart contract, which is a program that is executed automatically.

The ownership registration unit 4a records each ownership registration as one blockchain, an origin block is first generated, and blocks are connected and generated one after another for each ownership transfer registration. Smart contracts automatically execute transactions for generating blocks and recording data in blocks.

When the ownership registration unit 4a receives a registration instruction notification 17 containing digital content and copyright holder data from the communication unit 7a of the management communication device 7, the ownership registration unit 4a generates an origin block for ownership setting registration. Linking the digital content, content ID, NFT (non-fungible token) to the origin block, and copyright holder data (member ID, registration date, nationality, postal code, address, name, email address) , telephone number, transfer account or cashless card number, etc.) and a nonce value are multiplied by a hash function, encrypted and stored, and all transactions are automatically executed (smart contract).
Regarding the copyright holder data to be registered in the ownership registration section 4a, if the work to be registered is a derivative work that is a redesign of the primary work, the author must In addition to the author, the author of the primary work shall be included as the creator.

In addition, the ownership registration unit 4a receives the new owner's data (member ID, content ID, registration date, nationality, postal code, address, name, email address, telephone number, bank account or cashless card) from the sales contract unit 4c. Each time there is a notification 23 of a registration instruction (described later) including a number, etc.), a new block is generated in the blockchain 12 corresponding to the content ID by connecting it to the previously generated block using cryptography. A transaction is automatically executed in which the data of the new owner is recorded in the block in cryptography, and the data of the new owner is notified to the communication unit 7a of the management communication device 7 as a transfer registration report 24 and stored in the recording unit 7b. smart contract).

The digital content publishing unit 4b publishes the digital content recorded in the origin block of the blockchain 12, which is different for each author, as well as the name of the author and the name of the current owner in a list state. This disclosure does not include data that would allow prospective buyers to contact authors and current owners directly. Regarding the copyright holder data published together with the digital content published by the digital content publishing section 4b, if the copyrighted work to be registered is a secondary work that is a redesign of the primary copyrighted work, the author must: The author of the primary work as well as the author of the secondary work shall be included as the creator. Including the author of the primary work as the creator satisfies the right to publish one's name (moral right) under the Copyright Act. In particular, when the creator becomes famous, the value of digital content increases, leading to repeated transfers, reassignments, reassignments, and sales.

In this viewable state, it is preferable that the viewable content is in layers. Specifically, the first layer that can be accessed stores all digital content registered in the ownership registration section 4a (all digital content that differs for each author) into still images, videos, VR videos, and still images. For example, you can view digital content of one genre listed in a grid, and the second layer displays multiple videos of the digital content selected in the first layer. In some cases, for example, multiple videos in a square list can be viewed, and the content ID, author's name, current owner's name, and non-purchase viewing status or saleable viewing status are displayed. can be viewed in the third layer, and the digital content selected in the second layer can be viewed in an enlarged display state. For example, the digital content publishing unit 4b shown in FIG. 2 is a dedicated viewer, and a plurality of content IDs registered in the ownership registration 4a are displayed in the column on the right side of the display unit, and when one content ID is selected, the corresponding One piece of digital content created is displayed (open to the public).

[Digital content publishing department 4b membership procedures/browsing 18, 27, 33]
The purchase applicant performs membership procedures 18, 27, and 33 with the digital content publishing section 4b using his/her own communication terminal 9, 10, or 11. That is, after first obtaining a member ID, the user can view 18, 27, and 32 the digital contents published in the digital content publishing section 4b. Membership procedures require presentation of personal data (registration date, nationality, postal code, address, name, email address, telephone number, etc.). Viewing requires presentation of a member ID. At the membership procedure stage, there is no need to present a bank account or cashless card number.

[Switching from digital content publishing section 4b to sales contract section 4c]
When a purchase applicant browses the digital content publishing section 4b and selects the digital content or content ID that he/she wishes to purchase from among the published sellable digital contents and clicks on it, the access destination is the sales contract section. This means that the display screen has been switched to 4c. If the digital content is a derivative work that is a redesign of the primary work, the display screen of the sales contract section 4c will not display that the author of the primary work is the creator. . This is because it is sufficient that the current owner is displayed as the negotiation partner of the purchase applicant, and if the creator of the primary copyrighted work is also displayed on the display screen of the sales contract section 4c, the negotiation partner will not be known.

Once the access destination has been switched, the person wishing to purchase the item must present the member ID again and present the bank account or cashless card number, etc., as a condition for entering into the sales contract. Note that if the management institution 5 wants to introduce Ethereum or the like, procedures will be required to enable it.

Even when switching to the sales contract section 4c, the digital content continues to be displayed on the screen, the price offered by the owner is presented, and a purchase application can be made. Here too, personal information other than the owner's name is not disclosed, and direct negotiations between purchasers and current owners are not possible.
This will be explained in more detail below.

[Functions of the sales contract department 4c when the first purchase applicant B makes a purchase application]
When the first purchase applicant B browses the digital content publishing section 4b and clicks on the digital content, or sends a communication 19 for a purchase application to the sales contract section 4c using the communication terminal 9, the sales contract section 4c sends the copyright information to the sales contract section 4c. A notification 20 of the purchase application is sent to the communication terminal 8 of the rights holder A. Based on this notification 20, the copyright holder A can enter the member ID and content ID into the sales contract section 4c and perform the communication 21 with the following content, and can respond flexibly to sales negotiations. For example, when changing the price through negotiation, the copyright holder A should notify the sales contract department 4c of the price change etc. via the communication terminal 8, or check whether there are multiple purchase applications within a certain period of time.

When a sales negotiation is concluded between the author A and the first purchaser B, the first purchaser B transfers the purchase fee 22 to the account of the management institution 5 set up in the sales contract department 4c. . After confirming the transfer 22, the sales contract section 4c outputs a registration instruction notification 23 to the ownership registration section 4a.

Upon receiving this notification 23, the ownership registration unit 4a generates a second block by giving a nonce value to the blockchain 12 corresponding to the content ID, and adds the content ID and the previous owner (copyright holder) to this block. Record the name of the new owner (first transferee; second owner), member ID, contract date, purchase cost, etc., and record the name of the second block. A series of transactions for notifying the communication unit 7a of the management communication device 7 of the content transfer registration report 24 is automatically executed (smart contract).

The distribution money received by the management institution 5 is for maintaining the operation of the management institution 5. Furthermore, since the management institution 5 establishes the transaction management system 100 and is involved in registration of ownership and sales and sales, the management institution 5 pays taxes corresponding to sales profits to the national treasury, thereby ensuring smooth operation.

When the transfer is registered in the ownership registration section 4a, the first buyer obtains the status of a new owner (second owner) (the essence of ownership is not the reproduction right). The content published in the digital content publishing unit 4b is automatically changed to display the digital content stored in the origin block, display the content ID, display the author name A, and change the name of the new owner B. Ru. Thereafter, the new owner B can access the sales contract section 4c using the member ID and the content ID, and can notify the subsequent intention to resell the digital content, the resale price, the auction sale and its period, etc.

[Functions of the sales contract department 4c when the second purchase applicant C makes a purchase application]

If the second purchase applicant C wishes to purchase the content, the second purchase applicant C subsequently submits a purchase application 28 to the sales contract department 4c using the communication terminal 10, and then the sales contract department 4c sends a request to the communication terminal 9 of the second owner B. A notification 29 of the purchase application is issued. Based on this notification 29, the second owner B can enter the member ID and content ID into the sales contract section 4c and perform communication 25, thereby being able to respond flexibly to sales negotiations. For example, in the case of changing the price through negotiation, the copyright holder A must notify the sales contract department 4c of the price change (no code) through the communication terminal 8, or if there are multiple purchase offers within a certain period of time. If there are multiple purchase applications, it may be possible to display that there are multiple purchase applications and switch to auction sales.

When sales negotiations for the transfer of ownership from the first purchase applicant B to the second purchase applicant C are concluded, the second purchase applicant C shall 30 will be transferred to the account of . After confirming the transfer 30 of the purchase fee from the second purchase applicant C, the sales contract unit 4c outputs a registration instruction notification 23 to the ownership registration unit 4a.

After confirming the transfer 37 of the purchase fee from the second purchase applicant C, the sales contract unit 4c outputs a registration instruction notification 23 to the ownership registration unit 4a.

Upon receiving this notification 23, the ownership registration unit 4a generates a fourth block by giving a nonce value to the blockchain 12, and adds the content ID and the name of the previous owner (second owner) to this block. Then, record the name, member ID, contract date, purchase cost amount, etc. of the new owner (third transferee; third owner), and further record the contents of the fourth block as a transfer registration report 24 for management purposes. The transaction is automatically executed by notifying the communication unit 7a of the communication device 7 (smart contract).

When the liaison unit 7a receives the notification of the transfer registration report 24, the recording unit 7b records the same content as that recorded in the second block, and the accounting unit 7c records the same content as that recorded in the second block, and the accounting processing unit 7c Distribution remittance procedures 38 and 39 for remitting distributions to the respective accounts of those who were voters (here, copyright holder A and second owner B fall under this category), and the third purchase request.
