Research On Digital Copyright Protection Based On Blockchain Technology

In recent years,with the development of information network technology,literary digital works have witnessed explosive growth.This paper proposes a solution based on blockchain technology to solve the problems of insufficient evidence of rights protection and serious system centralization in the field of copyright.This scheme not only helps to avoid copyright information being tampered,but also helps to find copyright information,and effectively solves the maintenance problem in the copyright dispute process.Aiming at the originality of digital works,this paper applies the improved text matching model to copyright audit and improves the copyright audit mechanism.The purpose of this paper is to explore the use of blockchain technology and text matching technology to build a reliable and secure digital copyright storage system,so as to protect digital copyright more effectively.The main research achievements of this paper are as follows:(1)For the original detection of digital works,further research and innovation are made on the existing text matching model KNRM,and a text matching model combining KNRM and LightGBM algorithm is proposed.Gauss kernel features were extracted by KNRM,and LightGBM algorithm was used as a classifier for classification processing and prediction of the final matching results.The experiment shows that the fusion model KNRM-LightGBM can achieve better text matching effect.(2)For the application scenarios of digital copyright,the PBFT consensus algorithm is improved.An improved PBFT algorithm is proposed by introducing credit scoring mechanism and simplifying into two-stage protocol.The communication cost of the algorithm is calculated and compared with the original algorithm to verify the effectiveness of the algorithm.(3)For the problem of copyright information storage of digital works,combined with the characteristics of blockchain,such as tamper-proof and traceability,analyze the application demand of copyright registration.Combined with the proposed improved consensus algorithm,the alliance chain network is built,and a digital copyright registration system is developed to realize the trusted registration.Finally,the performance test is carried out through the experiment,and the test results prove that the system can meet the daily needs and effectively solve the problem of digital copyright information confirmation and documentation.
