Problems solved by technology

[0005] The research on the application of blockchain technology to the copyright protection of video media has different emphases from different perspectives, but did not summarize the application of blockchain technology in a specific frequency copyright transaction and traceability, and most of the research only stay at the research level

Embodiment Construction

[0043] The method for tracing the source of video copyright transactions based on the parent-child chain will be further explained in conjunction with the accompanying drawings.

[0044] Such as figure 1 As shown, the process of determining the identity of member nodes in the parent chain based on the parent-child chain video copyright transaction traceability method includes the following steps:

[0045] 1) All nodes that want to log in to the multi-factor authentication and traceability system of video works facing the alliance blockchain need to have their own private key. This private key is unique and can identify any node. The private key is also a member node The unique identity authentication code for logging into the alliance blockchain;

[0046] 2) After the member node is successfully verified, it enters the member node information verification system. The system mainly verifies and confirms the user identity of the member node. The system will compare and search t...

Abstract

The invention discloses a video copyright transaction traceability method based on the parent-child chain, which records the video production process and the video source code record that can uniquely identify the video on the private block chain (child chain), and the alliance block chain (parent chain) Nodes certified by member nodes can conduct copyright information transactions and traceability of video media resources, including: 1) Authenticated parent chain member nodes can access copyright transactions and traceability systems after certification; 2) Member nodes will The information of each step is stored in the sub-chain for right storage; 3) Embed the video with a watermark and obtain the video fingerprint; 4) Calculate the video ID card for each video; 5) The smart contract uses The matching algorithm automatically facilitates the completion of the transaction; 6) The video producer traces the track of the video owner and traces the pirated video leaker.

Description

technical field [0001] The invention relates to the technical field of transaction traceability of video copyright by blockchain, Ethereum and smart contracts, and specifically relates to a method for traceability of video copyright transaction based on parent-child chains. Background technique [0002] In recent years, digital media copyright protection has become more and more popular. Nowadays, not only the media streams circulating on the radio and television system and the Internet, such as music and video, have copyrights, but also the self-media uploaded by users on some video platforms also need to copyright these media data when it comes to value transfer. Transactions and traceability. At present, the number of users in my country's digital publishing industry has reached more than 1.8 billion, and the overall revenue of the digital copyright industry has reached more than 700 billion yuan. When the digital media copyright industry is developing rapidly, many cop...
