Description

A block chain based copyright management system {System for managing copyright based on blockchain}

The present invention relates to a block chain-based copyright management system. More particularly, the present invention relates to a method and system for distributing transaction history information on a copyrighted work, when a purchase history is generated for a copyrighted work based on a block chain, To a copyright management system.

The block chain, which is designed as a base technology for bit coin, has been used in a wider range of fields over time. The characteristic of the block chain is that it creates a variety of new services by enabling direct transaction systems with minimal brokerage commissions. Specifically, the characteristics of the block chain are as follows.

Block chaining is characterized by decentralization because it uses distributed computing resources rather than the central system. The block chain can also be transparently managed for all transactions occurring on the network. All transactions can be tracked from the time of transaction occurrence, access to open transaction records, and the effect of reducing transaction costs and regulatory costs. The block chain is also characterized by the impossibility of forgery and falsification. The block chain generates the block using the information of the previous block. Because blocks are all linked together like a chain, if you want to manipulate a specific transaction of a block, you must also change the information of all blocks created later. It is considered to be the most reliable technology for forgery because it is virtually impossible to hack 51% of the block chain network at the same time. The block chain also has the characteristics of scalability. Most block-chain technology is highly scalable with open-source software.

When examining the characteristics of such a block chain, the block chain can be applied to various fields such as port, medical, and copyright. In particular, efforts to solve copyright problems based on block chains have been tried in various ways.

Recently, social awareness of copyrights of copyrighted works has been raised, and consumers are increasingly afraid of using copyrighted works of unknown origin. As a result, more and more consumers are seeking to pay for and use copyright through their normal distribution channels. However, even if a copyrighted work is a copyrighted work, there are a variety of copyrighted items. Therefore, even if a copyrighted work is purchased through a normal distribution channel, there is a problem that a copyright owner gives a range to a consumer and a range that a consumer wants to use is different. The major factor in such a problem is the difficulty and complicated process of proceeding by the copyright item.

However, it is expected that the smart contract will be possible if the copyright management is performed based on the block chain. Accordingly, it is expected that various conventional dispute factors will be solved and the copyright transaction will be more convenient.

On the other hand, a related art is disclosed in Korean Patent Publication No. 10-2018-0014534.

The present invention makes it possible to deal with copyrighted works between a copyright holder and a consumer (a variety of items included in an author's property right and a moral right), and records the same in a block chain to establish trust, The purpose of the transaction is to make it easier and easier to carry out.

In addition, the present invention provides a consumer transaction for a copyrighted work, records a transaction record on a block chain, promptly responds to the occurrence of the transaction, The copyright owner can prevent the disadvantage of the copyright owner and allow the copyright owner to directly check the transaction history of his own work.

A copyright management system according to an embodiment of the present invention includes a copyright owner device for registering a copyrighted work with a copyrighted material providing server, a copyright management server for receiving and storing the copyrighted work from the copyright owner device, A content providing server for transmitting the copyrighted work to the user device and distributing the profit obtained by the validation transaction to the copyright holder side based on the copyright distribution information according to copyright, And a block chain network for requesting settlement by money and verifying a hash value generated based on a transaction for a user device and a work for receiving and viewing a requested work from the work providing server as the settlement is performed , The work is copyrighted 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 invention can facilitate transactions for subdivided copyright items such as the copyright of a secondary work between a copyright holder and a consumer. Accordingly, the present invention can expect the effect of activating a legitimate transaction for a secondary work.

Further, the present invention stores the copyright transaction history based on the block chain, so that the copyright holder can receive the royalties in a transparent manner.

In addition, the present invention can assist the user in registering only the verified work by judging the attempt to exercise the copyright on the stolen work and, in such a case, restricting the registration of the work. Accordingly, the present invention can prevent the problem of illegally paying royalties to a work that is not its own creation.

In addition, since the present invention provides a method of trading not only digital contents but also general rights related to copyrights, it is possible to utilize the works and activate the compensation system of the copyright owners.

In this application, the terms "comprises", "having", and the like are intended to specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, But do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof.

1 is a diagram showing a configuration of a copyright management system according to an embodiment of the present invention.

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

The copyright holder device 100 may include a copyrighted work such as a viewing ticket for permitting the creator to view a work created by a maker, including digital contents such as images and sounds, And register it for sale to an unspecified number. The work providing server 200 may register a work that can be sold and distributed to a work provided from the copyright holder apparatus 100 and generate a block so that the work can be traded based on the block chain. The information included in the generated block may correspond to an identification value of the copyrighted work data, a hash value of the copyrighted work data, a transaction, and the like. The transactions may also include copyright-related information, including smart contract-related information and copyright holder information.

The block chain network 400 can propagate a block in which corresponding transaction information is recorded to a node when a specific work is permitted to be sold to a user and to provide a service for a predetermined period of time set in advance. In addition, the block-chain network 400 may compare the values of the hash values of the blocks held by the plurality of nodes in order to determine whether the corresponding service is valid when the user device 300 requests the service of the work providing server 200 by the user equipment 300 .

Upon confirming the payment amount (password) transmitted from the user device 300, the work providing server 200 may distribute the proceeds of the work to a purse address of the registered copyright holder by a predetermined ratio. According to this process, the copyright owner can receive the royalty fee in proportion to the usage history of the user using the registered work.

According to various embodiments, the work providing server 200 may provide a password to a plurality of nodes constituting the block-chain network 400. At this time, the ciphers provided to the nodes constituting the block-chain network 400 may be a reward for providing a role for a server that distributes books for a plurality of agreements. The node constituting the block-chain network 400 may include a device of a user using a work and a device of a copyright holder which generates and provides a work.

2 is a block diagram illustrating a configuration of a work providing server according to an embodiment of the present invention.

2, the work providing server 200 may include a storage unit 210, a communication unit 220, and a controller 230, and the storage unit may store copyright related information 211 and copyrighted material data 212. The control unit 230 may include a copyright processing unit 231, a work registration processing unit 232, and a transaction processing unit 233 for each usage item.

First, the copyright related information stored in the storage unit 210 will be described in detail later with reference to FIG. The work data 212 is data of a work registered by the copyright holder. According to various embodiments, the work data is registered in the work providing server 200 and a hash value of the data is given (based on the predetermined hash function Or the hash value of the existing data can be confirmed. The hash value of the data may be stored in the block and provided to the neighboring nodes or the user device 300 receiving the copyrighted material viewing service. In this case, the neighboring node may refer to individual communicable devices constituting the block-chain network 400. The neighboring node may be classified into a node that verifies the entire block according to the characteristics of the node and a node that verifies only the Merkle hash value . The node that verifies the entire block may be, for example, a server that performs a cryptographic mining operation.

The communication unit 220 can perform communication with the copyright holder device 100, the user device 300, and the block chain network 400.

The communication unit 220 can receive a work request signal for browsing and possessing a work, creating a secondary work, and other smart works for copyright use from the user equipment 300 according to an embodiment of the present invention. In addition, the communication unit 220 can receive a work transmitted from the copyright holder apparatus 100. [ The work may include a digital content and a certificate to authorize the use of a work such as a play ticket of a play, a building, and the like. In addition, the work provided to the copyright offering server 200 by the copyright owner may include an authority certificate including some copyright to the work. For example, when a sound source composed by a composer is a copyrighted work, the authority of the music source, the MR production, and the sales right of the sound source may be registered as a transaction object. For the sake of convenience in this specification, contents related to a work which can be a target of a transaction, an authority certificate, and the like can be used as a whole as a work.

 Also, the communication unit 220 can communicate with a block-chain network. The block-chain network is a consensus system composed of a plurality of devices, and information on transaction details can be distributedly stored in a storage space of each node.

The controller 230 can process transactions such as a transaction of a work and distribution of royalties in a copyright management system according to an embodiment of the present invention. Specifically, the control unit 230 may include a copyright processing unit 231, a work registration processing unit 232, and a transaction processing unit 233 for each usage item.

The copyright processing section 231 can confirm and evaluate the copyright-related information of the work registered by the copyright holder. The above-mentioned copyright-related information may be information including the configuration of the copyright holder (the number of persons of the copyright holder, the distribution ratio of royalties per copyright holder, etc.), and the details will be described with reference to Fig. The copyright processing unit 231 can perform payment according to the ratio and the amount based on the copyright related information in which the copyright fee is registered in response to the occurrence of the transaction of the copyrighted work. Also, the copyright processing unit 231 can generate and record the result of performing the copyright processing operation related to the setting of the royalty payment and the payment of the royalty payment in the block. The transaction details related to the copyright processing operation recorded in the block can be propagated to the multiple nodes of the block-chain network 400. [

When the copyright owner registers the copyrighted work as a copyrighted work, the copyrighted work registration processing unit 232 can perform the verification of the copyrighted work and perform the registration as a copyrighted work. In this case, the verification means that the new work to be registered by the copyright holder is the same as the previously registered work and is a forgery work that is set differently from the copyright holder, but is not the same as the previously registered work, It may mean filtering on the work to be judged. Accordingly, the work registration processing unit 232 can prevent an unauthorized use of a copyrighted work.

For example, the work registration processing unit 232 can calculate the pattern code for the image file requested to be newly registered. The pattern code of the newly requested image to be registered can be compared with the pattern code value of the previously registered images, and if it is determined that the image is the same as the predetermined ratio or more, registration of the image may be restricted.

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

In addition, according to various embodiments, the work registration processing unit 232 can detect a work that is likely to be exploited for a crime or a work suspected of copyright infringement even if it is a newly registered work in which the same element does not exist. For example, based on the previously reported details (for example, notification of a photograph or a picture including a face of a specific person photographed without consent), the copyright registration processing unit 232 determines whether a photograph or image including a face of the specific person , The registration of the corresponding photograph or image can be restricted. Accordingly, it is possible to prevent registration of malicious works that violate laws such as portrait rights.

According to various embodiments, the work registration processing unit 232 may suspend and delete the transaction of the copyrighted work data 212 even if the registered work copyrighted data 212 is found to be in violation of the law including copyright. The copyright management system according to the various embodiments of the present invention can store only the information on the service transaction history and the copyright transaction history of the work in the block chain without storing the work data itself in the block chain. Accordingly, only the identification value (information corresponding to the category of the work, the name of the work) and the hash value of the work data can be recorded on the block chain, and the user can select the work data from the block chain And can download or stream directly through the work providing server 200.

However, the present invention is not limited to this, and the copyrighted work data may also be recorded on the block chain. In this case, because of the nature of the block chain, it is impossible to delete the copyrighted work data. .

The work registration processing unit 232 can register a work that can be processed for a work approved for registration, and receive a transaction request for the work from the user apparatus. The service item provided by the work providing server 200 can be divided into an item for which a service period is set (for example, a lending) and an item for which a period is not set (for example, own). In addition, the service item provided by the work providing server 200 can be classified according to the copyright item of the work. The copyright includes authorship rights and moral rights, and author's property rights include broadcasting rights, reproduction rights, distribution rights, exhibition rights, and copyright rights of secondary works. Author moral rights may include the right to publicity, the right to display names, and the right to maintain identity. Accordingly, the work providing server 200 can distinguish between a case where a specific work is limited to a broadcasting right and a case where a work right including both a broadcasting right and a copyright right is granted. In other words, the work registration processing unit 232 receives from the copyright holder information on the transaction amount per service item requested by the copyright holder, the range of the copyrightable item that can be traded, and the transaction amount per item of copyright that can be traded, and registers the information as information corresponding to the work .

The transaction processing unit 233 for each use item can confirm the amount of payment made by the user in accordance with the details using the copyright related service based on the previously registered copyright related information and store the transaction detail information in the body area of the block. At this time, the transaction processing unit 233 for each usage item can store not only the payment details but also the authorization information granted to the user as the information to be stored in the block. The transaction processing unit 233 for each use item may store smart contract execution information in a transaction according to various embodiments. For example, when the original copyright owner sells the copyright of the secondary copyrighted work to the proprietor of the secondary copyrighted work, the transaction processing unit 233 for each use item classifies the contents related to the transaction amount as well as the contract content regarding the category of the secondary work, Can be included. When the copyright owner claims the copyright of the secondary work later, the secondary work may be approved as a work that can be traded based on the smart contract content recorded in the transaction.

3 is a block diagram showing details of the copyright-related information 211 according to the embodiment of the present invention.

The copyright-related information 211 according to the embodiment of the present invention includes right distribution information 211a, copyright usage history information 211b, secondary copyright agreement information 211c, copyright amount transaction amount information 211d, copyright holder wallet address information 211e, Value < RTI ID = 0.0 > 211f. ≪ / RTI >

   First, the rights distribution information 211a for each copyrighted work may be information about distribution of royalty for a specific copyrighted work created by the copyright owner. At this time, the copyright distribution information 211a may include copyright payment information such as the name and distribution ratio of at least one copyright holder to be paid. If the work is a secondary work created on the basis of the original work, the author of the original work and the creator of the secondary work may both be registered as a copyright holder, but the author of the original work and the creator of the secondary work There may be a difference in the ratio of royalty payments. The ratio of the royalties paid by the authors of the secondary work and the original author can be set based on the contents of the consultation at the time of the contract of the secondary work, which can be referenced in the secondary work contract information 211c. The secondary work contract information 211c may be temporarily stored in the storage unit. When the original author authorizes the production right for the secondary work, the transaction details and the contract details are recorded in a block chain transaction and stored . Since the contents stored in the block chain are distributed to a plurality of nodes and the forgery and fugure is almost impossible, the storage history in the storage unit may be deleted after a predetermined time elapses.

The work utilization history information 211b may also be information temporarily stored in a storage unit for a preset period of time and permanently distributed and stored in a plurality of nodes. For example, when it is assumed that a one-week viewing service, a one-month viewing service, and a one-year viewing service are respectively present, the copyright usage history information 211b may be information that records service usage details of a user's work. The work usage history information 211b may include information on the frequency, rate, and the like of each service provided by the work providing server for a specific work. In addition, the work usage history information 211b may include information on a main transaction item (reading, downloading, second work, etc.) for a specific work.

The transaction amount information 211d for each copyright item according to the embodiment of the present invention may include a transaction amount for each copyright item to be set when the copyright holder permits the transaction for each item of the copyright. At this time, the copyright item can be divided into authoring property rights and moral rights. For example, if a copyright owner deals with his / her own work (eg, sound recording) only for broadcasting rights included in the author's property rights, if he / she authorizes a royalty fee of 20,000 won per work, , The amount of 2 million won per work can be settled. The transaction amount may be different depending on the item of the copyright to be traded, and the setting information of the copyright owner may be stored in the transaction amount information 211d for each copyright item. The transaction amount information 211d according to the copyright item can be used as reference data for calculating the transaction price when a transaction between the copyright owner and the consumer is made later.

According to the embodiment, the transaction amount information 211d per copyrighted item may include information related to the copyright of the secondary copyrighted work. For example, the transaction amount information 211d per copyrighted item may include information on whether or not a secondary work is allowed, an amount for authoring a secondary work, and a royalty payment rate for a secondary work.

The information related to the copyright of the secondary copyrighted work stored in the copyrighted item transaction amount information 211d may be used as reference data for the contract between the author and the secondary author. In accordance with the embodiment, The contract may be executed. For example, if the author of a secondary work requests a contract related to a secondary work, and the author authorizes the contract, the contract is automatically contracted according to the contents stored in the transaction amount information 211d per copyrighted item, .

As another example, a contract according to the contents stored in the transaction amount information 211d per copyright item may be automatically performed 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 per copyrighted item may further include information related to the copyright of the tertiary work, and when the information related to the copyright of the tertiary work is not included, a predetermined ratio is applied to the information on the copyright to the secondary work The value may automatically be used in contracts related to the copyright of the ternary work.

The copyright holder wallet address information 211e may be an address corresponding to an account for paying royalties to the copyright holder, and may be an address at which the encrypted money can be sent. At least one copyright holder's wallet address per work may be assigned.

The root hash value 211f for the copyrighted work may mean a data hash value of the copyrighted work itself. The hash value can be used as an indicator for determining whether the data is the same or not. The hash value means a result obtained by encrypting the hash value with a constant value regardless of the file size of the data. The hash value is usually assigned to files, and it is difficult to grasp the contents of the original data through the hash value because the hash value is calculated differently even if the file contents are partially changed. The hash value is used to determine whether the hash value is valid. Accordingly, the hash value can be used as an index for judging whether the newly registered work is the same data as the existing work.

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

4 is a flowchart showing a procedure of a work registration operation according to an embodiment of the present invention.

The work providing server 200 may determine that the request 405 for performing registration performed from the copyright holder device is performed. Thereafter, the work providing server 200 may perform the operation 410 of verifying the requested work. At this time, the verification operation performed by the work providing server 200 determines whether or not the same work existing in the web, such as plagiarism and forgery content, exists (e.g., whether it is a work registered as a public work) Or to restrict the registration of a copyrighted work.

On the other hand, in the case of a secondary work, inevitably the same element as the original work must be included. In such a case, if the work includes the information that the contract for the secondary work was executed by the original author, But otherwise the registration may be restricted as it will be detected to contain the same elements as the original. In accordance with various embodiments, the registration restrictions may be lifted if the work meets certain conditions and is found not to infringe on the copyrights and other legal issues (eg, portrait rights) of others.

In one embodiment, if there is no information about the contract performed previously, the work providing server 200 may automatically determine whether the work to be verified is a secondary work. For example, if the work to be verified includes the same element or more than a certain reference to a particular work, it can be judged to be plagiarism or secondary creation. For example, when the ratio of the same element is equal to or greater than a predetermined first criterion, the work providing server 200 determines that the plagiarism is a dead copy in terms of a dead copy, is greater than or equal to a second criterion lower than the first criterion, But it is not limited to this.

In addition, although the first and second criteria may be set according to the criteria set by the work providing server 200, different first and second criteria may be set according to the selection of the author for each work.

If it is determined that the work to be verified is a secondary work, the work providing server 200 acquires information about the primary work, and based on the information included in the transaction amount information 211d for each copyright item of the primary work, Whether it accepts the secondary work, and whether it allows the contract to be automatically executed for the secondary work.

If the primary work automatically permits the contract to be executed for the secondary work, the work providing server 200 automatically sets the contract based on the amount included in the transaction amount information 211d per copyrighted item of the primary work or the royalty rate , And information on the executed contract can be stored in the block and associated with the primary work and the secondary work (the work to be verified) and recorded in the block chain.

After completing the work verification operation, the work providing server 200 can perform the operation 415 of registering the copyrighted work data and the copyright related information from the copyright owner when it is determined that the requested work can be registered. The copyright-related information may include information related to the distribution of royalties, a copyright scope allowed by the copyright holder, a copyright amount, a transaction amount per service item, and wallet address information for receiving the royalties.

Thereafter, the work providing server 200 may generate the content to be stored in the block based on the registered work and the copyright related information, write the content in the block, and perform the operation 420 to propagate the same to the neighboring node. For example, the work providing server may store a work in a server, an identification value of the work, and copyright related information of the work in a block transaction item. According to various embodiments, the work providing server 200 can classify a work to be stored in a server and a work to be stored in a block transaction according to a file size or a format of the work. For example, the work providing server 200 may be configured to store in a block only a work having a text format of a certain size or less, and to store other works on the storage unit 210 of the work providing server 200.

According to various embodiments of the present invention, the operation 420 may be an operation of generating a new block based on the entire copyright information and the copyright information when the copyrighted work is approved through the verification process . Generally, the role of creating a block is a cryptographer, and in order to generate a new block, a problem is solved by inputting a nounce value. This value is an undefined value at the time of block creation and is a value that should be searched for new block creation. If it is found, a new block is created and this process is called mining. By such a mining process, the digger will obtain the cryptographic money as compensation.

According to various embodiments, the work providing server 200 of the present invention may generate a block corresponding to a work registration operation performed by the copyright holder apparatus 100, and may provide a compensation system for prepayment of the password. Accordingly, the copyright owner can obtain the same effect as registering a work in the work providing server 200 and receiving a pre-tax for the work.

Although the present invention has been described in detail with reference to the above examples, those skilled in the art will be able to make adaptations, changes and modifications to these examples without departing from the scope of the present invention. In other words, in order to achieve the intended effect of the present invention, all the functional blocks shown in the drawings are separately included or all the steps shown in the drawings are not necessarily followed in the order shown, It can be in the range.
