Research On Application Of Blockchain Technology In Copyright Registration System

With the rapid development of the digitalization of the Internet industry,the digital content industry is also accompanied by industrial upgrading,and people's awareness of copyright has awakened.More and more digital content creation has continued to increase.Currently,the digital publishing industry is in a fast-growing stage.As digital content works are being transmitted on the Internet,there is no special means to control the viewers.Therefore,malicious copy spread among browsers can easily cause infringement of digital works.These vicious acts curb the creativity of the creators of the works,infringe on the creators' legitimate rights and interests,crack down on the creative power of the creators of the entire society,and have a negative impact on the development of digital publishing-related industries.The creators of works protect their legal rights through copyright registration of works.At present,under the highly centralized management and registration mechanism of China's copyright registration system,there are problems such as personal privacy disclosure,information tampering,vulnerability to attack,and opaque information.Aiming at the current problems,this article applies the blockchain technology to the copyright registration system,and through experimental tests,the test results show that the system has the advantages of traceability,tamper resistance,openness and transparency,security and reliability,and low resource consumption.The main research contents of the paper are as follows:First,the existing copyright registration system is decentralized.To solve the distributed consistency problem,an egalitarian practical Byzantine fault tolerance algorithm(EPBFT)is proposed by using the practical Byzantine fault tolerance algorithm.This algorithm can guarantee dynamic node adjustment in peer-to-peer networks.By weakening the concept of primary node,each node is equal and efficient.By optimizing the consensus process,consensus efficiency and throughput are improved.The EPBFT algorithm has been experimentally tested in terms of throughput and consensus efficiency.Second,according to the problem of over-coupling of data and information in the copyright registration system,an architecture model that is divided by the concept of data layering is proposed.The architecture model that is divided by the concept of data layering is applied.The EPBFT consensus algorithm is used to solve the distribution problem in the blockchain network.The consistency problem has been significantly improved in terms of throughput,data security,stability and efficiency.Finally,through the improved consensus algorithm and the system model architecture,the copyright registration system based on block chain technology is implemented.The functions of the copyright registration system are realized through the needs analysis and the application of the algorithms and architectures mentioned above.Tests show that the system meets the requirements of the actual production environment.
