Description
Technical Field
The invention relates to a block chain-based copyright protection method, and belongs to the technical field of block chains.
Background
The block chain is a shared distributed database, data blocks are combined into a specific data structure in a chain mode according to a time sequence, and the data blocks are guaranteed to be untrustworthy, centralized and trusting shared general ledger in a cryptographic mode, so that data which are not falsifiable and counterfeitable can be safely stored and can be self-verified in a system. The distributed computing system is a brand-new decentralized infrastructure and distributed computing paradigm for collective maintenance, and has the characteristics of decentralized, distrusted, collective maintainability and reliable databases 4. The block chain technology provides strong credible record proof for all digital knowledge assets, the introduction of the block chain technology can greatly improve the operation efficiency of copyright asset management industry, and the problem of long and complicated industrial chain is solved from 4 links of right determination, right use, right maintenance and autonomous management.
According to the law of our country, registration of works is not a necessary procedure for copyright acquisition. The work is voluntarily registered. The copyright legitimately acquired by the author or other copyright holders is not affected whether the work is registered or not. But copyright registration is helpful for solving copyright disputes caused by copyright ownership and can provide preliminary evidence for solving the copyright disputes. Copyright registration from application submission to certificate acquisition typically requires a month at a cost of about 1200 dollars per piece, and requires a government agency (copyright authorities at each level) to accept and register the copyright, without the copyright registration agency having to go through any substantial review of the material submitted, but only a formal review. So when copyright disputes occur, the legal support that the certificate of copyright registration can provide is limited. The conventional authority copyright registration has the following disadvantages: the method has the advantages of more materials to be prepared, longer process, higher cost and unsatisfactory legal support force after copyright dispute appears.
Principle of copyright registration based on blockchain technology: (1) the characteristic that the blockchain is not changeable provides a new method for proving the existence of the works, and whether a picture, a segment of text or audio and video can be proved to exist through the blockchain. (2) The blockchain can provide proof for the existence of a specific time point, and the time point of work creation or the time point of copyright transaction is accurately recorded without any objection. (3) Based on the block chain construction principle, the block chain can provide unique evidence for copyright, wherein the time of submitting works, ownership attribution, copyright transaction and the like are all unique. (4) Because the block chain is not changeable, the existence of the recorded copyright and copyright transaction at a specific time point provides conclusive proof and provides powerful technical support for protecting digital copyright. (5) The blockchain does not distinguish large-scale media companies from authoring individuals, and anyone or organization can conveniently use the blockchain to register the copyright, so that innovation and authoring are encouraged, and the blockchain is highly matched with the basic purpose of copyright protection.
Blockchains can provide a powerful tool to maintain, track copyrights and copyright transactions. Compared with a government copyright registration mode, the copyright protection mechanism based on the block chain technology has the following advantages: (1) the decentralized and cryptographically secure nature of the blockchain database (backbone) makes it less likely to suffer catastrophic loss or failure, or hacking. (2) The registration process is almost instantaneous and can greatly simplify the flow and preparation of copyright protection. (3) The cost is extremely low and can be almost ignored. (4) Subsequent transactions of the work are also recorded in real time and can be tracked over the trading network. (5) Blockchain registration may allow more people to know that an author has ownership of a work given the openness of the blockchain. (6) The block chain is more helpful for solving copyright disputes.
At present, some patents disclose copyright protection methods based on block chains, and Chinese patent 108537694A discloses a method for protecting copyright on the block chains, which can confirm the copyright at the earliest relative time, has absolute initiative for own works, and has more public transparency and credibility, and the invention can also combine with intelligent contracts to sufficiently guarantee the buying and selling of the copyright and the copyright break-up transaction, but has the defect that the public can hardly see the basic information of the copyright to determine whether to buy or not; meanwhile, each copyright information in the block chain is dispersed, and the information without classification can be inquired.
