A Certificate Storage Method for Confirming Video Copyright and Tracing the Source Based on Alliance Chain

Abstract

In recent years, with the development and update of business models and emerging technologies, there have been more and more forms of piracy and infringement of online video works. It is difficult for the department with copyright to confirm the copyright of the work and trace the source of piracy. Alliance blockchain technology can be partially decentralized, highly controllable, and data is not public by default, providing new ideas and methods for solving the above problems. The thesis proposes a multi-factor confirmation and traceability depositing method (MCTA) for video works of alliance blockchain. First, the alliance member nodes store the signature information of the person in charge in each step in the private chain during video production; second, the smart contract pre-processes the source video, implants watermarks and calculates video fingerprints, and creates a video ID for each video; Finally, double-factor authentication for the suspected infringement of pirated video to confirm the right. Carry on simulation experiment through Truffle+MiniNet+SimBlock. The results show that the method proposed in the thesis is effective and feasible for depositing video works.

Distributed Energy Transaction Model Based on the Alliance Blockchain in Case of China

“…In terms of cost, transactions in the alliance chain only need to be verified by a few trusted nodes with high arithmetic power, and there is no need for network-wide validation, so the transaction costs are lower. Literature [22], it is proposed that the use of Alliance blockchain technology can provide new ideas and methods for the copyright department to confirm the copyright of works and trace the source of piracy, which reflects the abovementioned characteristics of the Alliance chain such as high controllability and non-disclosure of data by default. In literature [23], it is pointed out that the microgrid based on the alliance chain has the advantages of high efficiency and easy supervision.…”
