Description

Block chain system for transacting art work and managing information of art work and control method thereof

An embodiment of the present specification relates to a block chain system for managing information on works of art and a control method of the system. More specifically, using the blockchain system to register information on works of art, to provide information and to support transactions, and to distribute a part of the revenue generated in connection with the provision of information and transactions to artists and control them it's about how to

As transactions for works of art become active, a trading system that can receive transaction-related information and support transactions even online rather than offline is being formed. The system used for the transaction of such works of art must secure openness that allows multiple users to access the system, and must provide the ability to provide the owner or copyright holder with the costs incurred in connection with the transaction.

In order to satisfy the characteristics of such an art transaction system, a transaction system using block chain is being discussed. The characteristic of blockchain is that it creates a variety of new services by enabling a direct transaction system with minimized brokerage fees. Specifically, the characteristics of the block chain are as follows.

Blockchain has the characteristics of decentralization because it uses distributed computing resources rather than being operated by a central system. In addition, blockchain can transparently manage all transactions that occur on the network. All transactions can be traced from the time of transaction occurrence, anyone can access publicly available transaction records, and it is possible to obtain the effect of reducing the cost of nurturing transactions and regulation. In addition, the blockchain has a characteristic that it is very difficult to forge or falsify using a conventional method, because a plurality of nodes share information about the block created using the information of the previous block and verify it. am. In the blockchain system formed in this way, when information related to a specific transaction is changed, information related to the corresponding ledger must be changed. is virtually impossible in a normal system, so it is a decentralized system, but reliability can be secured and the risk of forgery is relatively low.

Considering the characteristics of such a block chain system, it can be applied to various fields such as ports, medical care, and provision of administrative documents as well as art transactions. Efforts to solve problems related to art transaction using these features based on block chain are being tried in various ways.

In recent years, social awareness of copyright for works has been increasing, and consumers' antipathy towards using works whose copyright holders are unknown is increasing. Accordingly, more and more consumers are willing to pay for and use copyrights through normal distribution channels. However, even for copyrighted works, there are various items of copyright, and therefore, even if the work was purchased through a normal distribution channel, there were cases where the range granted by the copyright holder to the consumer was different from the range that the consumer wanted to use. The main factor in such a problem may be the difficulty and complicated process in proceeding with the transaction by copyright item.

However, smart contracts are possible when copyright management is performed based on block chain, and it is expected that various conventional dispute factors will be resolved and more convenience will be obtained in copyright-related transactions.

However, the currently widely used trading system is a centralized trading system. Transactions generated in the transaction system may be processed by a central server, and processed transaction details may be stored in a central database. Only the operator of the transaction system can have access to read and write transaction details. Accordingly, the transaction details are not transparently disclosed to the user, and there is a possibility of manipulation of the transaction details. That is, the centralized transaction system does not guarantee transparency and immutability of transaction details.

In order to provide immutability and transparency of transaction details, the transaction system can be implemented through blockchain technology. For example, a decentralized trading system may be implemented through a blockchain (eg, Ethereum) that provides smart contract technology. All transaction details can be recorded on the blockchain. Blockchain can guarantee immutability and transparency of data recorded on the blockchain. Anyone can monitor all transaction details (auditable), and manipulation of transaction details becomes difficult.

However, it is difficult to find examples of specifically applying the characteristics of such a block chain to a system related to art transactions, and a typical block chain is mainly applied to a system related to the transaction of virtual currency. A specific method for application and a system using the same are required.

An embodiment of the present specification has been proposed to solve the above-described problems, and an object of the present specification is to provide a system for art transaction using a block chain system and a method for controlling the same. Another embodiment of the present specification aims to provide a system capable of registering information about an artwork and an artist, providing information thereto, and performing a transaction on the registered artwork, and a control method therefor. Another embodiment of the present specification aims to provide a work of art transaction system that introduces the concept of a right of payment and a control method therefor so as to provide the artist with the profit generated according to the provision of information on the work of art and the transaction of the work of art .

In order to achieve the above object, the method of the server related to the work according to an embodiment of the present specification comprises the steps of: receiving information related to the artist; receiving information about a work corresponding to the artist; checking detailed information of the work encrypted with the artist's personal identification information; Receiving a detailed information inquiry request for the work from the first terminal; transmitting an approval request for inquiring detailed information about the work to a second terminal corresponding to the work; receiving an acknowledgment response from the second terminal; receiving a cost corresponding to the detailed information inquiry request from the first terminal; checking information on payment rights for the work; transmitting at least a portion of the cost to a collection right person based on the payment right information; and transmitting the detailed information to the first terminal based on the approval response.

A server related to a work according to another embodiment of the present specification includes a transceiver for transmitting and receiving information with other nodes; and controlling the transceiver, receiving information related to the artist, receiving information on the work corresponding to the artist, confirming detailed information of the work encrypted with the artist's personal identification information, and receiving the information from the first terminal Receives a detailed information inquiry request for the work, transmits an approval request for detailed information inquiry on the work to a second terminal corresponding to the work, receives an approval response from the second terminal, and the first terminal receive a cost corresponding to the detailed information inquiry request from and a control unit for transmitting information to the first terminal.

According to an embodiment of the present specification, it is possible to provide a decentralized system for providing and trading art information, and through this, it is possible to smoothly perform information provision and transaction. In addition, according to an embodiment of the present specification, a virtuous cycle structure can be generated by providing a system that introduces the concept of the right to repossession in relation to the provision and transaction of art information, thereby providing the creator with the revenue generated from the art work.

In addition, according to the embodiment of the present specification, a block chain system is implemented in relation to the right of payment so that transactions and information on art can be provided, and the revenue generated from this is provided to counterparties and artists in the system, thereby providing an art transaction structure. has the effect of being simpler.

In addition, components and '~ units' may be implemented to play one or more CPUs in a device or secure multimedia card.

Meanwhile, in an embodiment, in order to ensure transparency and immutability of transaction details, a transaction service may be provided through a blockchain network. However, depending on the type of blockchain, a large transaction fee may be charged when a transaction is performed. In an embodiment, the transaction fee may be provided through a virtual currency related to the system, and the fee may be provided to at least one of a trader, an original author, and a copyright holder according to conditions set in advance or according to a contract. In an embodiment, what is described as a node corresponding to a trader, an original author, and a copyright holder may correspond to a terminal corresponding to a corresponding subject, and for example, may mean to transmit a fee to a terminal corresponding to the corresponding subject.

In a blockchain-based trading system that charges a transaction fee, for example, a transaction that creates an order (e.g. a buy order, a sell order), a transaction that cancels an order, etc. Transaction fees may also be charged for previously occurring transactions. Therefore, if all transactions are processed through the blockchain network, the provider or user of the transaction service may have to bear excessive transaction fees.

Transaction fees may be paid in, but not limited to, the native currency of the blockchain. However, in the embodiment of the specification, it is described that the fee can be transmitted to a specific entity in the native currency of the corresponding block chain, but depending on the embodiment, the native currency of another block chain may also be used, which is exchanged between currencies according to a specific node in the system. can be done through A user may directly purchase a native currency to use the transaction system and pay a transaction fee through the purchased native currency.

Referring to FIG. 1 , a conceptual diagram related to an operating method of a platform related to a work trading system according to an embodiment is shown.

In the embodiment, the platform 100 is described as a transaction history-related platform, but is not limited thereto, and can perform overall roles such as providing information related to works, providing procedures for work transactions, and providing work-related payment rights functions. What is described in the embodiment is to explain the operation procedure in the overall system.

In step 110 , the artist and transaction participants of the work may register at least one of identification (ID) information and work information in the platform 100 . The identification information may include public identification information that is disclosed for identifying each subject within the system and personally identification information that is not disclosed. In an embodiment, the public identification number is used for processes such as information exchange and transaction with other entities within the platform, and personal identification information is not disclosed information, so that the platform can utilize the uniqueness of the user. A separate server can be installed for internal identification information management. Meanwhile, in an embodiment, the platform 100 may be configured with only public identification information, but personal identification information may be separately provided for user authentication and the like. In an embodiment, an artist's work may be encrypted based on the artist's personal identification information and stored in a server or a writer's terminal. This is later

In step 120, each subject may perform a transaction, and the platform 100 may provide approval or related information therefor, and accordingly perform an operation of changing the owner and providing a related fee to the artist. On the other hand, the reliability of information exchanged between users on the platform 100 can be secured between nodes in the platform 100 through a block chain. In order to secure the reliability of such information, a procedure in which the corresponding information is exchanged between nodes in the system may be performed.

In step 130, each subject of the platform may manage its own ledger information, and may manage the related cryptocurrency transmission according to the occurrence of an event. In an embodiment, the ledger information may be information including at least a part of information exchanged inside the platform 100, and according to an example, at least one of information related to a work, a transaction history of a work, and history information inquiring a work may include In addition, cryptocurrency exchange may include transmitting a fee to a corresponding subject when an event in which a fee is generated within the platform 100 occurs. As described in the following embodiment, the fee may be transmitted to at least one of the artist and the owner, and the fee may be transmitted to the corresponding subject according to the information inquiry about the work and the transaction process of the work. In all embodiments, the ledger can prove the current ownership related to the work using data recorded in the past, and when the transfer of ownership occurs, new data can be documented in the ledger.

In step 140, the platform 100 is connected to an external commercial server, and as an API is provided, the platform function can be extended through an external server and unique information. In an embodiment, the external server may be a commercial work transaction related service, and may provide at least some of the ledger information managed inside the platform 100 by providing an API to the outside. The external server can access the platform 100 through the API to check the work-related information, and can also transmit cryptocurrency to the subjects inside the platform 100 through the API. On the other hand, information disclosed to the outside through the API can be set in a limited way, and limited information can be provided compared to the subjects inside the platform. As an example, identification information for a user inside the platform 100 may be converted on a provided API and provided to the outside, and work information may also be provided to the outside only in part.

In an embodiment, since the platform 100 through the block chain can exchange information with external entities through the API, it is possible to simultaneously pursue the advantages of decentralization and intensive data management.

In addition, through this scalability, external participation can be maintained, enabling additional writers and transaction participants to sign up inside the platform.

2 is a schematic diagram for explaining a block chain system according to an embodiment of the present specification.

The block chain system may be configured to include nodes 231, 232, and 233 each having data. The nodes 231, 232, and 233 mean units of components constituting the block chain system. Each of the nodes 231 , 232 , 233 may be configured to include one or more servers and the like. In the blockchain system, when the client 200 wants to change the data recorded in the blockchain system, for example, when the token holder wants to change, the consensus between the nodes 231, 232, 233 Go through the process. Accordingly, each of the nodes 231 , 232 , and 233 has blocks 221 , 222 , and 223 including the same data.

On the other hand, the block chain system may be configured to include information about the smart contracts (211, 212, 213). The smart contracts 211 , 212 , and 213 are source codes that can be executed on a server or a computing device linked to the server. The smart contracts 211 , 212 , and 213 may be configured to perform a predetermined procedure when a specific condition is satisfied at the time of execution. In addition, the smart contracts 211 , 212 , and 213 can verify the integrity of the result value for the performed procedure by consensus on the result value. For example, if a condition for transferring ownership of a token is set in the smart contract 211, 212, 213, and a request that satisfies the condition is received, the smart contract 211, 212, 213 is a preset condition Accordingly, blocks 221 , 222 , and 223 for a transaction transferring ownership of the token can be verified and reflected in the nodes 231 , 232 , and 233 of the block chain system. Through such a smart contract, it is possible to set the fee information for each work and information about the right of payment.

In addition, in an embodiment, the number of nodes may be increased to ensure the integrity of the consensus, and the integrity of blocks in the corresponding node may be supplemented through a supernode including the corresponding nodes. Supernodes can check the information on the consensus status within the Supernode, and by comparing this with the information of other Supernodes, the reliability of the information written in the block can be secured.

Through such a user terminal, a user may be provided with information within the system, and may perform work-related transactions.

4 is a diagram for explaining a method for registering artist information in a transaction history management system according to an embodiment of the present specification.

Referring to FIG. 4 , a process of registering artist-related information in the server constituting the transaction history management blockchain system through the writer terminal in the embodiment is illustrated.

In step 410, the writer terminal may transmit an artist information registration request to the server. In an embodiment, the request for registering artist information may include information related to the artist. As an example, information about the author's name and biography may be included, and information on this may be requested to be registered with the server. In an embodiment, author information may be authenticated by a separate certification authority, and authentication information may also be transmitted. The authentication information is information that guarantees the reliability of the artist's information, and this authentication procedure can be performed even when the work information is later uploaded. Also, in an embodiment, identification information corresponding to the corresponding artist may be allocated by the writer terminal or server.

In step 415, the server may receive the artist information and review the validity of the information. If the validity is confirmed, the artist information can be distributed and registered in the block chain system, and the cryptocurrency wallet information corresponding to the writer can be generated and transmitted back to the writer terminal so that the writer can receive cryptocurrency in the system. In an embodiment, the server may check the authentication information and then perform a registration procedure for it, and if it is not authenticated, it may transmit a request for authentication to a separate authentication node. In an embodiment, distributed registered author information may be written on a distributed ledger.

If the artist information is distributed and registered, the writer terminal and the server may check the registered artist information in step 420 . The server may transmit the information registration result to the artist terminal, and the artist may receive such result information, check the wallet information, and receive a fee related to the work later through the wallet of the corresponding address. In addition, the server can also check the registered artist information for future block updates. In addition, if the identification information of the artist is allocated by the server, the allocated identification information can be provided to the writer terminal, and the writer terminal can check the identification information and use the identification information to transmit and receive information with the system later. .

After that, the artist can check the work information through the artist terminal. In an embodiment, image information and unique identification information of the work may be checked, and the corresponding information may be converted for upload. In an embodiment, the work information may be information obtained through a separate device, and the corresponding information may be obtained through communication and confirmed for registration of work information. For example, the artist terminal may perform a procedure for receiving an image of a work photographed in high quality and uploading it in a plurality of qualities. In addition, according to an embodiment, the server may divide and store the images uploaded by the writer's terminal into various qualities. In addition, the identification information about the work may include identification information about the artist, and information allocated by the artist terminal and information allocated by the server may be additionally included.

In step 430, the artist terminal may transmit a work information registration request to the server. The request may include information about the work, and may also include low-quality encoded image information for the work. In addition, work identification information can be transmitted, and partially assigned work identification information can be transmitted to the server. For example, the artist information and the work identification information allocated from the artist terminal may be transmitted to the server, and in the case of the server, the corresponding work identification information allocated by the server may be additionally matched to the corresponding work in addition to the corresponding information. In this way, by uploading a low-quality image on the system, requesting detailed information about the future work from the artist, and providing the information, the artist can secure a fee for this. In an embodiment, at least some of the servers of the system may also obtain and store high-definition image information from the writer's terminal, receive a certain amount of commission according to a request from another user, and provide the information to the corresponding user.

In step 435, the server may generate a distributed ledger related to work information based on the received information. The corresponding work information ledger may be registered as a sub-ledger in the artist information ledger, but is not limited thereto, and may be distributed and recorded as an independent ledger based on mutually referenced information. This may include creating a ledger related to specific information among a plurality of servers constituting the blockchain system and triggering it to be written. By such a triggering operation, a plurality of servers constituting the block chain system create a corresponding ledger and enter information about it through consensus, thereby securing the reliability of the block chain.

In addition, in an embodiment, the work information ledger may include information related to the right of payment. In the embodiment, the information related to the right of payment is to provide a part of the revenue to the artist when the artist of the work generates a profit related to the work. The recipient may be the subject of the right of payment. In addition, in the embodiment, a cryptocurrency wallet corresponding to each payment right may be created, and when the payment right is transferred, the ownership of the cryptocurrency wallet is transferred to another person, so that the subject of the payment right is not exposed to the outside, and the transfer of the payment right is possible. can

In step 440, the terminal and the server can check the distributed ledger-related information with each other, and check that the work information is registered in the corresponding system.

By registering artist information and work information in the system in this way, work and artist information can be checked within the system, and thus, work transactions can be performed smoothly through the system.
