Embodiment

[0022] The present invention combines the block chain and the cloud platform in the field of digital content copyright traceability. All transaction processes of digital content producers on their content will be recorded on the block chain, and the digital content will be stored in the cloud in an encrypted form. In the platform, the transaction process of digital content is automatically completed through smart contracts; the process is as follows: figure 1 shown, including the following steps:

[0023] Step 1. Design the overall framework of the digital copyright traceability system based on blockchain and cloud platform, such as figure 2 , including physical hardware layer, blockchain layer, middleware framework layer, application layer, terminal equipment and digital content producers from bottom to top, among which digital content producers include audio and video distributors, education industry, individual original creators, publishers and distribute a pair of public...

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...
