Building method of digital copyright tracing system based on block chain and cloud platform

Abstract

The invention discloses a building method of a digital copyright tracing system based on a block chain and a cloud platform. The method comprises the following steps: designing a general framework of the digital copyright tracing system based on the block chain and the cloud platform; building a block chain consensus mechanism, wherein nodes in the block chain reach a consistent consensus on the aspects of node reliability and data real-time performance; designing a digital content storage way based on the block chain and the cloud platform, wherein the block chain stores a Hash function value formed after dimension reducing processing of digital content, and the cloud platform saves digital content on which a digital content producer performs a digital signature with a private key; building a digital content transaction platform based on the block chain to perform a registration transaction and an authentication transaction of the digital content; and building a digital content copyright tracing model, and performing tracing by using a chain-style relation of a Hash chain in the block chain. Through adoption of the method, safe and effective propagation of digital products can be realized, and the problem that digital content copyrights cannot be traced is solved.

Description

technical field [0001] The invention belongs to the technical field of cyberspace security, and in particular relates to a construction method of a digital copyright traceability system based on a block chain and a cloud platform. Background technique [0002] In recent years, mobile application services have developed rapidly. According to statistics, the number of Internet users in 2016 exceeded 6.49 [0003] billion, and the Internet penetration rate is over 47.9%. The average person spends more than 26 hours online per week, among which mobile Internet users account for 85.8%, which means that eight out of ten people use mobile phones to surf the Internet. Mobile applications have been involved in all aspects of daily life, and a wide variety of mobile application services such as shopping, social networking, and travel are dizzying. More and more digital content such as e-books, music, and movies are traded and disseminated on the Internet, and the problems of copyrig...
