Scenario analysis on the application of blockchain technology in copyright field


The scenario of blockchain technology applied to copyright can be divided into the following aspects: physical copyright, digital product copyright and non-standard copyright.

Among them, the copyright of physical products is mainly operated offline, and the information needs to go through the chain process. If the certificate is issued to the original producer, the certificate information will be recorded on the blockchain.

Its advantage is that government departments use new technology to record these information, which is open, transparent, traceable, convenient for judicial proof, and reduce copyright disputes.

The works of words, music, art, photography and other works corresponding to the copyright of digital products are easy to be put on the chain. The works submitted on the blockchain copyright platform will be recorded into blocks with the author’s information and marked with corresponding timestamps. The subsequent transfer of copyright will also be verified with timestamps, which is very convenient for the confirmation of copyright. Music, video and article content, which can be consumed online and recorded completely, are more suitable to use blockchain technology to realize copyright protection. Creators can set corresponding permissions for their own works. For example, users can only see, can’t download, copy and other operations, which can ensure that users can’t save and spread original works in other channels at will, which can largely guarantee the uniqueness of producers’ original works in the chain. Content creators can also create value by creating content; content consumers can create value by forwarding, praising, commenting, investing and other forms to achieve free circulation of value.
Scenario analysis on the application of blockchain technology in copyright field
With the development of Internet industry, many copyrights are non-standard data, such as some user data, algorithms, etc., which have strong data attributes and can be copied and spread at any time. From the seller’s point of view, how to ensure that the data is not abused after it is sold (for example, some buyers require to return the transaction payment after copying the data); and how to ensure that the buyer can know the availability and authenticity of the data before obtaining the data? How to avoid sellers selling the same data to multiple users in the market? And how do buyers know they are buying a valid data? They are all problems that need to be solved. One way to solve these problems is to make sure that what is traded is the same for both parties. This can also be achieved by “zero knowledge proof, homomorphic encryption” and other technologies. The technology of “zero knowledge proof” can ensure that the information is in line with its requirements without the disclosure of information content. In this way, the interests of both sides can be guaranteed, and the “homomorphic encryption” technology in cryptography can realize that after the processing and decryption of confidential information, the decrypted information still retains the changes in the processing process. This technology can be applied to the transaction and processing of protected content.

In real life, non-standard things still need to establish a recognized rule to reduce transaction costs. What needs to be solved in the future is to make a standardized definition of non-standard products, then write these standard rules in the smart contract, and finally realize the whole transaction process through blockchain technology.

Well, the above is the scenario specific analysis of blockchain technology in the copyright industry. Remember to take notes!
