Description

How to protect copyright using blockchain {METHOD FOR PROTECTING COPYRIGHT USING BLOCKCHAIN}

The present invention relates to a method of protecting copyright using a block chain, and more specifically, copyright protection that prevents unauthorized distribution and sharing of designer's work images using a block chain, and protects information of customers and designers. It's about the system.

In general, blockchain technology is a technology that records and stores transactions made over network communications in a reliable and safe way. Blockchain network is a system in a distributed environment that enables the exchange of digitized assets or transactions, and the history of electronic transaction details generated in a peer-to-peer (P2P) network using a shared ledger. Record. Since the blockchain network uses a decentralized or decentralized consensus mechanism, forgery and alteration of transaction details by a third party is virtually impossible, and the reliability and transparency of transaction details can be guaranteed.

Digital Rights Management (DRM) is a technology that prevents illegal and unlimited copying of contents that are digitized and can be easily distributed through information and communications networks, and manages that only legal users can use digital contents. DRM is a technology that collectively manages content creation, distribution, and management, and is a technology that composes a comprehensive digital rights management system that includes content packaging, content distribution, content usage billing, content monitoring, and the like.

However, in the conventional DRM, various information of contents is stored in a centralized server, and there is a problem of forgery and alteration through hacking, and a large investment in security facilities is required to prevent this.

In order to solve this problem, the present disclosure provides a copyright protection system that prevents the uninterrupted distribution and sharing of designer's work images using a block chain, and protects information of customers and designers.

According to an embodiment of the present disclosure, a block is generated by generating each hash for user information, designer information, and designer's work image using a block chain, and generating one transaction based on the generated hash value. The transaction data is shared by broadcasting to other nodes.

According to an embodiment of the present disclosure, when one or more images are input, one or more similar images having a certain degree of similarity are extracted using an image matching system, and each of the input image and the retrieved extracted image is transferred to the hash value extraction system. A hash value is generated by input, and the permission for use, distribution, and/or change can be determined by comparing the generated hash value with the hash value for the image in the blockchain.

A method of protecting copyright using a block chain according to an embodiment of the present disclosure includes: generating a hash value for each of user information, designer information, and a designer's work image; Generating one block by generating one transaction based on the generated hash value; And sharing the generated transaction data by broadcasting the generated block to other nodes.

A method of protecting copyright using a block chain according to an embodiment of the present disclosure includes the steps of: receiving an input image; Extracting an image similar to the input image; Generating a hash value for each of the input image and the extracted similarity image; Comparing the hash value for the image in the blockchain based on the generated hash value; It may include determining whether to block the use, distribution, and/or modification of the input image based on the comparison result.

According to various embodiments of the present disclosure, user information, designer information, and hash value information for each of the designer's work image are stored in a blockchain to prevent unauthorized distribution and sharing of images and protect customer and designer information. I can.

However, the present disclosure is not limited to the embodiments disclosed below, but may be implemented in a variety of different forms, and only these embodiments make the present disclosure complete, and those skilled in the art to which the present disclosure pertains. It is provided only to fully inform the person of the scope of the invention.

In the present disclosure, the'hash value' is expressed as an indexed value of input information and may be a unique value of blockchain data, based on a hash value of designer information, a hash value of user information, and a hash value of a designer image. Blockchain data having an index value that is not the same as other blockchain data (e.g., blocks, transactions) can be created.

1 is a diagram illustrating a block chain-based copyright protection system according to an embodiment of the present disclosure. The blockchain-based copyright protection system 100 may include a blockchain platform 110, which is an environment in which data is stored in blocks. In one embodiment, the blockchain platform may be in the form of a private blockchain.

As shown, blocks of the block chain may be composed of a block header and a block body. The block header stores a record describing the data content of the block, and the block body stores transaction details, that is, transactions contained in the block.

The transaction may include the designer's image and information on the designer who owns the copyright of the image, and may further include user information using the designer's image. The designer image, designer information, and user information may be stored in the block body as one index value.

In one embodiment, upon receiving the image, the unique information of the block chain data stored in the blockchain platform 110 and the unique information of the input image may be compared. For example, when an image is input, an index value (for example, a hash value) corresponding to the image is calculated, and the calculated index value is compared with the image hash value included in the block in the blockchain to determine whether the image is in circulation. I can. An embodiment of this process will be described in detail in FIG. 2.

2 is a flowchart illustrating a method of protecting copyright based on a block chain according to an embodiment of the present disclosure. Blockchain-based copyright protection method 200 may begin with a step of inputting an image for protecting copyright. For example, the crawled image may be input by crawling an image accessible on a network (eg, on the Internet) using an image crawling system (S210). Each of the crawled images may be input to the image matching system (S220). In the image matching system, one or more images similar to the crawled image may be extracted (S230). For example, the image matching system inputs the received image to a deep learning model, extracts feature information of the image, and compares the extracted feature information with feature information of a pre-stored image to extract one or more images with a certain degree of similarity. have.

A hash value for each image may be extracted by inputting the crawled image and the extracted similar image to the hash value extraction system (S240). The generated hash value and the hash value of the designer image in the blockchain are compared (S250), and if the hash value is the same, the designer information and user information stored in the block are compared to determine whether to block use, distribution, and/or modification. It can be done (S260). For example, if it is decided to block, a document describing copyright infringement can be sent to the owner of the crawled image, or measures can be taken to prevent the use and/or distribution of images published through the website. If the hash value is different, it may be permitted to use, distribute, and/or modify the crawled image (S270).
