Problems solved by technology

Copyright protection includes processes such as copyright registration, copyright transaction, copyright monitoring, infringement evidence collection, and copyright protection. The existing blockchain-based digital copyright protection scheme mainly focuses on providing protection for copyright confirmation and copyright transaction links. It is relatively rare to provide security protection solutions for copyright transfer, copyright protection and other processes
In addition, the existing digital product copyright protection scheme based on blockchain technology lacks a mechanism to prevent malicious behaviors of both parties, that is, after a malicious buyer receives a correct file, he falsely claims that the file is a wrong file and does not pay the corresponding money; Malicious seller sends wrong documents but still takes money paid by buyer
This not only damages the economic interests of both parties to the transaction, but also brings difficulties to judicial evidence collection

Embodiment Construction

[0071] A block chain-based digital copyright protection method provided by the embodiment of the present invention is divided into six stages for specific implementation:

[0072] In the preprocessing stage, the copyright protection center registers on the blockchain network, deploys the smart contract for copyright protection to become the owner of the contract, and then sets the blockchain account address of the registration agency.

[0073] In the stage of copyright registration, after the copyright owner completes the creation of the work, he encrypts the creative work and verified identity information and sends it to the copyright protection center. After the copyright protection center decrypts and reviews the creative work, the copyright protection center is responsible for embedding copyright information in the original work , and save the information of digital works through smart contracts, so as to achieve the effect of confirming the rights of digital works.

Abstract

The invention aims to provide a digital copyright protection scheme based on a block chain, copyright services of the whole process are designed in combination with a block chain technology and a digital watermarking technology, and five functional requirements of copyright registration, copyright query, copyright transaction, copyright transfer and copyright protection are met. In addition, an OptiFairSwap protocol is realized through a smart contract to complete effective delivery proof and prevent malicious behaviors of both transaction parties, and a pirate tracking function is realized in combination with a digital fingerprint technology. Once the works are confirmed on the block chain, subsequent transactions can be recorded in real time, so that the works are traceable and traceable in the whole life cycle of creation, circulation and use, and powerful technical guarantee and conclusion evidence are provided for judicial evidence collection. Meanwhile, in the copyright transaction and copyright transfer process, a copyright owner can directly participate in the copyright management of own works, the transaction process is open and transparent, and the royalty is settled in a transparent manner.

Description

technical field [0001] The invention belongs to the field of multimedia information security protection, and specifically relates to a digital copyright protection method of block chain technology and digital watermark technology. Background technique [0002] With the rapid development of computer technology and network technology, the dissemination of digital media has become convenient, and people can quickly upload and share digital multimedia (such as photos, music, movies) through personal websites or social networks. At the same time, these media contents are likely to be downloaded and distributed by unauthorized users, which will seriously damage the interests of content owners. To protect traditional copyrights, content owners need to provide digital works and personal information as copyright information to copyright registration agencies. The copyright protection agency stores it in a centralized server for processing, and there are risks such as single point of...
