Description

Blockchain based copyright management system

The present invention relates to a copyright management system based on blockchain. More specifically, in the present invention, when a purchase history is generated for a copyrighted work based on a blockchain, the transaction fee information is included in a transaction within the block and distributed to multiple nodes, thereby paying the copyright fee corresponding to the purchase history. It relates to a copyright management system that performs.

Blockchain, which is designed as a foundation technology for Bitcoin, has been used in more various fields over time. The unique feature of blockchain is the creation of a variety of new services by enabling a direct transaction system with minimal brokerage fees. Specifically, the characteristics of the blockchain are as follows.

Blockchain is decentralized because it uses distributed computing resources rather than a central system. In addition, the blockchain can transparently manage all transactions occurring on the network. All transactions can be tracked from the time of the transaction, anyone has access to public transaction records, and the benefits of cultivating transactions and reducing regulatory costs. In addition, blockchain is characterized by the forgery is impossible. The blockchain creates a block using the information of the previous block. Because blocks are all connected like a chain, manipulating a particular transaction in a block also requires changing the information in all subsequently created blocks. Hacking 51% of blockchain networks simultaneously is virtually impossible, making it the most reliable technology for forgery and alteration. In addition, the blockchain is characterized by scalability. Most blockchain technologies are open source software and are highly scalable.

When examining the characteristics of such blockchain, blockchain can be applied to various fields such as port, medical care, and copyright. In particular, efforts to solve the copyright problem based on the blockchain have been attempted in various ways.

In recent years, social awareness of copyrights on copyrighted works has been improved, and consumers' dissatisfaction with using copyrighted works that are unknown to conventional copyright holders has increased. Accordingly, more and more consumers are willing to pay and use copyright value through normal distribution channels. However, even if the copyrighted work has a variety of items of copyright, according to this, even if the copyrighted work is purchased through a normal distribution channel, there are cases where a problem arises due to the difference between the copyright holder's grant to the consumer and the range the consumer wants to use. The main factor of such problem is that it is difficult and complicated process in proceeding transaction by copyright item.

However, smart contracts are possible when the copyright management is performed based on the blockchain. Accordingly, various conventional disputes are resolved and it is expected to be more convenient in copyright-related transactions.

According to the present invention, a copyright transaction between a copyright owner and a consumer (authorship property, various items included in a personality of a work) is possible, and a record is written on the blockchain to establish a trust, thereby establishing a copyright between the copyright owner and the consumer. The goal is to make transactions easier and more convenient.

In addition, the present invention provides a consumer transaction for the copyrighted work using cryptocurrency, record the transaction record on the blockchain, and in response to the transaction occurs, the content transaction is circulated as soon as the copyright is paid to the copyright holder as cryptocurrency. You can prevent the copyright holder's penalties from and allow the copyright holder to directly check the transaction history of your work.

A copyright management system according to an embodiment of the present invention receives a copyright holder device that registers a copyrighted work in a work providing server and receives the work from the copyright holder device, and requests from a user device as a valid transaction using cryptocurrency is performed. The asset providing server for transmitting the copyrighted work to the user device and distributing the proceeds obtained through the valid transaction as a cryptocurrency to the copyright holder based on the right distribution information for each copyright, and a cipher to receive a desired work from the asset providing server. Request a payment in currency, and include a blockchain network for verifying a hash value generated based on a transaction for a user device and a copyrighted work received from the asset providing server and viewed as the payment is performed; , The copyrighted work Data that can be protected by literary, music, theater, art, architecture, photography, video, shapes, and a computer program and may include a certificate of authority to make it available.

Various embodiments of the present disclosure may support a simple process of trading a detailed copyright item such as a second copyrighted work between a copyright holder and a consumer. Accordingly, the present invention can expect the effect of the legitimate transaction activation for the secondary work.

In addition, the present invention stores copyright-related transaction details based on the blockchain, so that the copyright holder can be paid transparently.

In addition, the present invention can support the registration of the verified work by determining the attempt to exercise the copyright on the stolen work and restricting the registration of the work in such a case. Accordingly, the present invention can prevent the problem of illegally being paid for copyrights for works that are not their own creations.

In addition, the present invention provides a method for trading not only digital content but also general rights related to copyrights, thereby enabling the use of copyrighted works and the rightful compensation system of copyright holders.

In this application, the terms 'comprise' or 'have' are intended to indicate that there is a feature, number, step, action, component, part, or combination thereof described in the specification, and one or more other features. It is to be understood that the present invention does not exclude the possibility of the presence or the addition of numbers, steps, operations, components, components, or a combination thereof.

Referring to FIG. 1, a copyright management system according to an exemplary embodiment of the present invention may include a copyright holder device 100, a work providing server 200, a user device 300, and a blockchain network 400. In this case, the blockchain network 400 may refer to a consensus system composed of a plurality of nodes (computers, mobile devices, etc.).

The copyright holder's device 100 may include a work created by the producer in the asset providing server 200 (including a digital ticket such as an image or a sound, and a certificate of authorization such as a viewing ticket allowing the creator to view the created work). Can be sent and registered for sale to an unspecified majority. The asset providing server 200 may register a work provided from the copyright holder device 100 as a sellable and distributeable work and generate a block to be traded based on the blockchain. In this case, the information included in the generated block may correspond to an identification value of the asset data, a hash value of the asset data, and a transaction. In the transaction, copyright related information including smart contract related information and information about the copyright holder may be recorded together.

The blockchain network 400 may propagate a block in which transaction information corresponding thereto is recorded to a node when a specific asset is sold to a user and authorized to provide a service for a predetermined period of time. In addition, the blockchain network 400 may compare the Merkle hash value of a block held by a plurality of nodes to determine whether the corresponding service is valid when the user device 300 requests a service for an asset from the asset providing server 200 later. .

When the asset providing server 200 confirms the payment (cryptocurrency) transferred from the user device 300, the asset providing server 200 may distribute the proceeds for the asset by a preset ratio to the wallet address of the registered copyright holder. According to this process, the copyright holder may be paid a copyright fee in proportion to the usage history of users using the copyrighted work.

According to various embodiments of the present disclosure, the asset providing server 200 may provide a cryptocurrency to a plurality of nodes constituting the blockchain network 400. In this case, the cryptocurrency provided to the nodes constituting the blockchain network 400 may be a reward for providing a role as a server that stores and stores books for a plurality of agreements. The nodes constituting the blockchain network 400 may include a device of a user who uses a work and a device of a copyright holder who creates and provides a work.

Referring to FIG. 2, the asset providing server 200 may include a storage 210, a communicator 220, and a controller 230, and the storage may store copyright related information 211 and copyright data 212. The controller 230 may include a copyright processor 231, a copyright registration processor 232, and a transaction item processor 233 for each item used.

First, copyright related information stored in the storage unit 210 will be described in detail later with reference to FIG. 3. The asset data 212 refers to data of a work registered by a copyright holder, and according to various embodiments, the asset data is registered in the asset providing server 200 and given a hash value for the corresponding data (based on a preset specific hash function). Given a calculated hash value), or a hash value of existing data can be confirmed. In addition, the hash value of the data may be stored in a block and provided to neighboring nodes or a user device 300 that receives a copyright browsing service. In this case, the neighboring node may mean an individual device capable of communicating in the blockchain network 400, and may be classified into a node verifying the entire block and a node verifying only the Merkle hash value according to the characteristics of the node. . The node verifying the entire block may be, for example, a server performing a cryptocurrency mining operation.

The communication unit 220 may communicate with the copyright holder device 100, the user device 300, and the blockchain network 400.

According to an embodiment of the present invention, the communication unit 220 may receive a copyright request signal for viewing and owning a copyrighted work, generating a second copyrighted work, and smart contract for other copyright use from the user device 300. In addition, the communication unit 220 may receive a work transmitted from the copyright holder device 100. The copyrighted work may include a digital document, and a certificate of content authorizing the use of a copyrighted work such as a ticket for a play or a building. In addition, the copyrighted work provided by the copyright holder to the work providing server 200 may include a certificate of authority including some copyrights of the copyrighted work. For example, when a sound composer composed by a composer is the present work, a right to a sheet music sales right, an MR production and a sale right, etc. of the sound source may be registered as a transaction object. In the present specification, all of the contents related to a work that may be a subject of a transaction, a certificate of authority, and the like may be used as a work as a whole.

In addition, the communication unit 220 may communicate with the blockchain network. The blockchain network is a consensus system composed of a plurality of devices, and information about transaction details may be distributed and stored in some storage spaces of each node.

The controller 230 may process operations such as trading a copyrighted work and distributing copyright fees in a copyright management system according to an exemplary embodiment of the present invention. In detail, the controller 230 may include a copyright processor 231, a copyright registration processor 232, and a transaction item processor 233 for each item used.

The copyright processor 231 may identify and evaluate copyright related information of a work registered by a copyright holder. The copyright-related information may be information including the composition of the copyright holder (number of copyright holders, distribution ratio of copyright fees per copyright holder, etc.), and details thereof will be described with reference to FIG. 3. The copyright processing unit 231 may perform a payment based on a ratio and an amount based on pre-registered copyright-related information in response to a transaction of a work. In addition, the copyright processing unit 231 may generate and record a result of performing a copyright processing operation related to setting a copyright fee and payment of a royalty fee in a block. As such, the transaction details related to the copyright processing operation recorded in the block may be propagated to multiple nodes of the blockchain network 400.

If the copyright registration processing unit 232 intends to register a newly created work as a work to claim copyright, it may verify the work and register it as a work. In this case, the verification means that the new copyrighted work to be registered by the copyright holder is the same as a previously registered history and the forgery work in which the copyright holder is set differently. This may mean filtering of the determined work. Accordingly, the copyright registration processing unit 232 can prevent the case of unauthorized theft of the copyrighted work exists.

For example, the asset registration processing unit 232 may calculate a pattern code for an image file that is newly registered. The calculated pattern code of the newly requested image may be compared with pattern code values of pre-registered images, and if it is determined that the image is equal to or more than a preset ratio, registration of the image may be restricted.

In addition, according to various embodiments of the present disclosure, the copyright registration processing unit 232 may determine whether the same data is obtained by comparing hash values unique to the copyrighted works excluding copyright related information. Accordingly, the copyright registration processing unit 232 may restrict the registration for the newly requested copyrighted work when the registered work is different from copyright-related information and the hash value of the copyright data is the same.

In addition, according to various embodiments of the present disclosure, even when a new registered work in which the same element does not exist, the copyright registration processing unit 232 may detect a copyrighted work or a copyrighted work that may be abused. For example, the asset registration processing unit 232 requests a new registration request for a photo or video including a face of a specific person reported based on previously reported details (eg, a report on a photo or video including a face of a specific person photographed without consent). If necessary, registration of the corresponding picture or video may be restricted. As a result, it is possible to prevent the registration of malicious works in violation of laws such as portrait rights.

According to various embodiments of the present disclosure, even if the registered copyright data 212 is found to violate a law including copyright, the copyright registration processing unit 232 may suspend and delete the transaction of the copyrighted work. The copyright management system according to various embodiments of the present disclosure may store the work data itself on the blockchain without limiting the service transaction details and copyright transaction details of the work. Accordingly, on the blockchain, only an identification value (information corresponding to the category and name of the copyrighted work) and a hash value of the asset data can be recorded on the blockchain, and the user does not have to store and store the asset data in the blockchain network. It can be directly downloaded or streamed through the asset providing server 200.

However, the present invention is not limited thereto, and the asset data may also be recorded on the blockchain. In this case, since the deletion is impossible due to the characteristics of the blockchain, the asset registration operation performed by the asset registration processing unit 232 may perform a more complicated verification process. It can be done through.

The asset registration processing unit 232 may register a work that is approved for registration as a tradeable work and receive a transaction request for the corresponding work from a user device. The service item provided by the asset providing server 200 may be classified into an item (eg, rental) having a service period defined and an item (eg, owned) having an undefined period. In addition, service items provided by the asset providing server 200 may be classified according to copyright items of the copyrighted work. Copyrights have copyright and copyright rights, and copyright rights include broadcast rights, reproduction rights, distribution rights, exhibition rights, and copyrighted works. Second, copyright rights may include rights of promulgation, statement of right, and right of identity. Accordingly, the asset providing server 200 may distinguish a case in which a specific asset grants only a broadcast right and a case in which all copyright rights including a broadcast right are granted. That is, the copyright registration processing unit 232 receives information about the transaction amount for each service item, the range of tradeable copyright items, and the transaction amount for each item of tradeable copyright from the copyright holder and registers the information corresponding to the asset when the copyright is registered. Can be.

The transaction processing unit 233 for each item of use may check the amount of payment corresponding to the details of the user's use of the asset-related service based on the registered copyright-related information, and store the transaction details in the body area of the block. In this case, the transaction processing unit 233 for each use item may store the authority information granted to the user as well as the payment details as the information stored in the block. According to various embodiments, the transaction processing unit 233 for each use item may store smart contract performance information in a transaction. The transaction processing unit 233 for each item of use, for example, when the original copyright owner sells the copyright of the second copyright work to the copyright owner of the second copyright work, the transaction contents as well as the contract contents regarding the category of the second copyright work as well as the details related to the transaction amount are recorded. Can be included. When the second copyright holder claims the copyright, the second copyright work may be approved as a tradeable work based on the smart contract contents recorded in the transaction.

Copyright-related information 211 according to an embodiment of the present invention is the rights distribution information 211a for each work, the work usage history information 211b, the second work contract information 211c, copyright value transaction amount information 211d, copyright holder wallet address information 211e and root hash for each work It can be stored including the value 211f.

First, the copyright distribution information 211a for each asset may refer to information on copyright royalty distribution for a specific work created by the copyright holder. In this case, the right distribution information 211a for each work may include information on payment of copyright fees such as the name and distribution ratio of at least one copyright holder who is subject to copyright payment. When the copyrighted work is a secondary work generated based on the original work, both the author of the original work and the author of the second work may be registered as the copyright holder, provided that the copyrighted work and the second work of the original work are provided. There may be differences in the rate of payment of royalties. The ratio of the copyright payments of the second copyright author and the original author may be set based on the agreement at the time of the second copyright contract, which may be referred to in the second copyright contract information 211c. The second asset contract information 211c may be temporarily stored in the storage unit, and when the original author trades a production right for the second asset, the transaction details and contract details may be recorded and stored in a blockchain transaction. Can be. Since the contents recorded in the blockchain are distributed and stored in a plurality of nodes, the forgery is almost impossible, and the details of the storage in the storage unit may be deleted after a predetermined time elapses.

Similarly, the asset usage history information 211b may also be information that is temporarily recorded in a storage unit for a predetermined period of time and permanently distributed and stored in a plurality of nodes. The asset usage history information 211b may be information that records a service usage history of a user's asset. For example, assuming that a weekly browsing service, a one month browsing service, and a one year browsing service exist, The asset usage history information 211b may include information about a frequency, a ratio, etc. for each service item provided by the asset providing server for a specific asset. In addition, the asset usage history information 211b may include information on main transaction items (view, download, secondary copyright production right, etc.) for a specific asset.

Transaction amount information 211d for each copyright item according to an embodiment of the present invention may include a transaction amount for each copyright item that is set when the copyright holder permits the transaction for each item of copyright. At this time, the copyright item may be divided into copyright and copyright. For example, if a copyright holder trades his work (eg, sound recording) only for the broadcasting rights included in the copyright of the work, a copyright of 20,000 won per work is assumed. You can set a price of 2 million won per asset for the transaction. The transaction price may be different according to the copyrighted items traded as described above, and the setting information of the copyright holder may be stored as transaction amount information 211d for each copyright item. The transaction amount information 211d for each copyright item may be used as a reference for calculating a transaction price when a transaction between the copyright holder and the consumer is made later.

According to an embodiment, the transaction amount information 211d for each copyright item may include information related to the copyright of the second copyrighted work. For example, the transaction amount information 211d for each copyright item may include information on whether a second copyrighted work is allowed, an amount for authoring a second copyrighted work, and a copyright payment rate for the second copyrighted work.

Copyright information related to the second copyrighted work stored in the item 211d may be used as a reference when the contract between the author and the second author, depending on the information stored in the transaction price information 211d per copyright item depending on the embodiment The contract may also be carried out. For example, a second work author may request an author for a second work related contract, and the author automatically accepts the work based on the contents stored in the transaction amount information 211d for each copyright item without further discussion of the detailed conditions. Can be performed.

As another example, a contract may be automatically performed according to the contents stored in the transaction amount information 211d for each copyright item without a separate request and approval process. The contract execution method according to the present embodiment will be described in detail below.

In addition, the transaction amount information 211d for each copyright item may further include information related to the copyright of the third work, and when information related to the copyright of the third work is not included, a predetermined ratio is applied to the information about the copyright in the second work. Values may also be automatically used for contracts relating to copyright in tertiary works.

The copyright holder's wallet address information 211e is information corresponding to an account for paying a copyright fee to the copyright holder, and may refer to an address to which a cryptocurrency can be sent. At least one copyright holder's wallet address may be assigned per work.

The root hash value 211f for each asset may refer to a data hash value of the copyrighted work itself. The hash value can be used as an index for determining whether the data is identical. The hash value means the result value encrypted with a constant value regardless of the file size of the data. Since the hash value is usually given to all files, and the hash value is calculated differently even if only a part of the file content is changed, it is difficult to grasp the contents of the original data through the hash value. The hash value is used to check whether or not. Accordingly, the hash value may be used as an index for determining whether a newly registered work is the same data as an existing work.

According to various embodiments of the present disclosure, when a work is divided into a plurality and stored in different nodes and downloaded to the user device 300, the root hash value 211f for each work is changed to confirm that the last downloaded file is the same as the original file. Can be used.

The asset providing server 200 may determine that the request 405 is performed to register the copyright holder's device. Thereafter, the asset providing server 200 may perform operation 410 for verifying a copyrighted work. At this time, the verification operation performed by the asset providing server 200 determines whether the same work existing on the web including plagiarism and forgery content exists (eg, whether the work is registered as a public work), and if there is a registration request. It may be an operation of restricting registration of the copyrighted work.

On the other hand, in the case of a secondary work, it must inevitably include the same elements as the original work. In such a case, if the work includes information that the contract for the second work has been performed with the original author, the work may be registered as a work that can be registered. It may be admitted, but otherwise the work may be detected as containing the same elements as the original work, so registration may be restricted. According to various embodiments, the restriction on registration may be canceled when it is confirmed that the work satisfies predetermined conditions and does not infringe the copyright and other legal issues (eg, portrait rights) of another person.

In one embodiment, when there is no information on the contract that has been performed, the asset providing server 200 may automatically determine whether the verification target work is a secondary work. For example, when a work to be verified includes the same element as a specific work or more than a predetermined standard, it may be determined to be plagiarism or a secondary creation. For example, the asset providing server 200 determines that plagiarism is considered dead copy when the ratio of the same element is equal to or greater than a first predetermined criterion, and is equal to or greater than a second criterion set lower than the first criterion and is less than or equal to the first criterion. It can be judged as a secondary creation, but is not limited thereto.

In addition, the first criterion and the second criterion may be based on a criterion set in the work providing server 200, but different first and second criteria may be set for each work according to the selection of the author.

If it is determined that the work to be verified is the second work, the work providing server 200 obtains information on the first work, and the first work is based on information included in the transaction amount information 211d of the copyrighted item of the first work. Information about whether to permit secondary works and whether to allow contracts on secondary works to be automatically obtained can be obtained.

If the primary work permits to automatically contract for the second work, the asset provision server 200 automatically contracts the contract based on the amount or copyright rate included in the transaction amount information 211d of the copyright item of the primary work. It can be performed, and the information about the executed contract can be stored in relation to the primary work and the secondary work (the work to be verified) and recorded in the blockchain.

If the work providing server 200 determines that the work requested to be registered after the work verification has been completed, the work providing server 200 may perform operation 415 for registering work data and copyright related information from the copyright holder. The copyright-related information may correspond to information related to distribution of copyright fees, copyright range allowed by the copyright holder, transaction amount for each copyright item and service item, and wallet address information for receiving the copyright fee.

Thereafter, the asset providing server 200 may generate content to be stored in the block based on the registered copyright and copyright related information, record the content in the block, and perform operation 420 of distributing the content to the neighbor node. For example, the asset providing server may store the copyrighted work on the server, and the identification value of the copyrighted work and the copyright related information of the corresponding copyrighted work in a transaction item within the block. Alternatively, according to various embodiments, the asset providing server 200 may classify the asset to be stored in the server and the asset to be stored in the transaction within the block according to the file size or format of the asset. For example, the asset providing server 200 may be configured to store in a block only an asset having a text format of a predetermined size or less, and control to store other assets on the storage 210 of the asset providing server 200.

According to various embodiments of the present disclosure, operation 420 may be an operation of generating a new block based on the copyrighted work and all copyright information thereof when the copyrighted device is registered and approved through a verification process. . In general, the block generator is a miner of cryptocurrency, and in order to generate a new block, a problem is solved by inputting a nonce value. This nonce value is not defined at the time of block creation, and it is a value to be found for creating a new block. When it is found, a new block is created and this process is referred to as mining. By the mining process like this, the miner gets the cryptocurrency as a reward.

According to various embodiments of the present disclosure, the asset providing server 200 may generate a block in response to a copyright registration operation performed by the copyright holder device 100, and may provide a reward system for prepaying cryptocurrency. Accordingly, the copyright holder may obtain the same effect as registering a work on the work providing server 200 to receive a prepayment tax on the work.

Although the present invention has been described in detail with reference to the above examples, those skilled in the art can make modifications, changes, and variations to the examples without departing from the scope of the invention. In short, in order to achieve the intended effect of the present invention, it is not necessary to separately include all the functional blocks shown in the drawings or to follow all the orders shown in the drawings in the order shown; Note that it may fall within the scope.
