Research On Digital Copyright Protection Based On Blockchain Technology

In the information age,with the continuous development of information technology,the traditional copyright is gradually moving closer to digitalization,digital copyright arises at the historic moment and plays an increasingly important role.However,the progress of technology also makes the reproduction and dissemination of infringing pirated resources easier and faster,thus the protection of digital copyright is in a dilemma.At the same time,blockchain technology brings a rare opportunity for digital copyright protection based on its unique technical advantages.The digital copyright protection system based on blockchain technology is the inherent demand of the development of digital copyright in our country.Under the traditional digital rights management mode,the cost of copyright registration is high,it takes a long time,and the process is a little tedious.Digital copyright protection can not keep up with the needs of copyright protection;In addition,the traditional copyright trading mainly depends on the participation of the third-party information platform,and the information asymmetry between the two sides of the copyright transaction limits the diversified development of copyright.The increased transaction consideration in order to ensure the profit space of the third-party information platform also reduces people’s willingness to pay for works.The application of blockchain technology can help China’s digital copyright protection system to solve these problems.First of all,because of the decentralization of blockchain,there can be no more central nodes in the digital copyright chain.This can greatly reduce the manpower,material and financial resources consumed by the national copyright management agencies,digital copyright service platforms and digital copyright holders for digital copyright protection.Secondly,based on the untamperable characteristic of blockchain technology,the data information of the nodes on the chain exists forever and cannot be changed once uploaded,and at the same time,the relevant nodes are linked to each other in chronological order to ensure the traceability of the information on the chain,which makes it simple and efficient to investigate and deal with infringing and pirated resources under the dual effects of untamperability and traceability.In addition,the reduction of the cost of digital copyright protection will also contribute to the smooth development of copyright protection.Thirdly,under the blockchain technology,the two sides of the copyright transaction can be in direct contact,and the blockchain technology,as the bottom support,will not limit the development of specific applications on the chain.in addition,with the continuous emergence of new technologies,the diversified development of digital copyright can be carried out flexibly.Finally,under the digital rights management mode based on blockchain technology,the traditional third-partyintermediary platform loses its central position in copyright trading,and the innovation of digital copyright trading mode reduces the cost paid by both sides of copyright transactions.so that copyright demand can achieve digital rights trading with less consideration,which helps to improve people’s willingness to pay for knowledge.Science and technology is a double-edged sword,on the one hand,blockchain can strongly enter the field of digital copyright protection based on its technological advantages and gradually become the best choice to get rid of the current dilemma of digital copyright protection;on the other hand,under the current technical conditions and legal environment,the use of blockchain technology for digital copyright protection still has its potential risks.At present,the construction of digital copyright protection system based on blockchain technology is faced with the following problems: first,the current blockchain digital copyright application market is mixed,and the relevant legal norms are missing.Ordinary authors can not identify whether the platform they use meets the technical requirements of blockchain,and the effectiveness of the author’s certificate on the platform can not be guaranteed.Second,under the role of block chain decentralization,the implementation of legal supervision on the chain is hindered,and the legitimacy of the content of digital copyright works can not be guaranteed.Third,the block chain digital copyright protection system confirms the rights of the complete work and the pre-prepared content of the work without distinguishing the content,so that the work can enter the transaction link before it is completed,and the creative idea can be realized in advance.In addition,the complete control of the copyright owner limits the space for the fair use of copyright;Fourth,the digital copyright protection system of blockchain operates under the dual functions of technical norms and legal norms,and they do not have a clear scope of application,so it is difficult to determine which norms to seek relief from when problems arise.Fifth,in the blockchain digital copyright protection system,except for the other third parties on both sides of the copyright transaction,as well as the platform itself can not know the content of the work,which makes it difficult to judge the substantial similarity of the two works and to identify plagiarized works.In order to reduce the applicable risk of the blockchain digital copyright protection system,in view of the legal problems faced by the system,there are the following suggestions: formulate supporting legal norms as soon as possible,adopt the approval system for the blockchain digital copyright application platform,and uniformly certify the certificate qualifications of the relevant platforms by the government to ensure the effectiveness of ordinary authors’ certificates;Vigorously promote intelligent supervision,emphasize the appropriateness and flexibility of legal supervision,and make use of intelligent contracts for industry supervision and endogenous supervision to ensure the development space of blockchain digital copyright protection system.Formulate the model text of the intelligent contract,realize the differential responsibility distribution of different copyright demanders through the format terms,clarify the boundary of the fair use of copyright,and at the same time use the block chain technology to develop the secondary market of digital copyright trading.the second benefit of the work in the secondary market isdistributed between the original copyright owner and the work user according to the proportion agreed in the previous period,under the condition that the rights of the copyright owner are not damaged.To achieve the win-win interests of copyright owners and the public;Clarify the scope of application of technical norms and legal norms,legal norms are the basic behavior norms of all parties in the block chain digital copyright protection system,and technical norms can only be used to make up for the vacancy of legal norms.The contact traceability of the work under the blockchain technology can be displayed accurately and intuitively,and the plagiarism comparison table of the infringing works can directly show the similarity of the specific content in color.Through the intelligent detection of the plagiarism comparison table built into the blockchain digital copyright application system to help copyright owners protect their rights.
