Design And Implementation Of Digital Copyright Management System Based On Blockchain

With the rapid development of information and digital technology,the number of digitalinformation produced by people in daily life and social activities is increasing.In addition,strengthening digital rights management is becoming more and more important for the protection of digital content.Traditional copyright management platform uses the architecture of centralized database,which is not suitable for the development requirements of the current digital age.In order to solve the problems of low efficiency,high cost,easy privacy disclosure and insufficient security existing in the current traditional copyright management platform,this paper designs and implements a digital content copyright management system based on blockchain considering the characteristics of blockchain technology.Blockchain technology has the characteristics of traceability,tamperability and decentralized distributed storage,which fully meets the needs of digital rights management.This platform is based on the Hyperledger Fabric blockchain framework.On the one hand,in order to ensure the originality of copyright confirmation content,this platform uses Sim Hash text matching algorithm and PHash image matching algorithm to analyze the originality of copyright registration content.On the other hand,to solve the problem that blockchain can't store large number of data,this platform uses IPFS interstellar file system to expand the blockchain storage.Based on the research status of copyright management,this paper analyzes different user requirements.Besides,this paper designs several functional modules for different user groups,and provides users with friendly front-end interface.After that,this paper implements and tests the functions of the whole system.The system proposed in this paper is an application of blockchain technology and a feasible solution to the existing problems in the field of digital content copyright management.
