AI Technical Summary

Technical Problem

In existing technologies, NFTs can only represent ownership of digital works, not intellectual property rights, and therefore cannot effectively protect the copyright of creators.

Method used

By generating creator user DID and public-private key pairs through the blockchain network, and combining them with the public-private key pairs of copyright certification agencies, the encrypted transmission and hashing of work information are realized, generating original certification SBT, and binding the creator ID on the blockchain. Asymmetric encryption and hash algorithms are used to ensure information security and accuracy.

Benefits of technology

It achieves effective protection of copyright, binds creator reputation through SBT, ensures information transparency, traceability and immutability, enhances the deterrent effect of infringement and the security of the appeal process.

Abstract

The application provides a copyright protection and complaint method and system based on a blockchain, and comprises the following steps: a supervisory authority sends a credit result to a blockchain network unit; a first public-private key pair and a second public-private key pair are generated through the blockchain network unit; first application information encrypted by a public key in the second public-private key pair is sent to a copyright authentication agency; the copyright authentication agency decrypts the first application information by using a private key in the second public-private key pair; the copyright authentication agency verifies the first signature information; the copyright authentication agency makes an originality determination, stores the result to the blockchain and broadcasts in the node; when the copyright of a work is infringed, a complaint is filed, and the infringement will be permanently marked. The whole process of the application is carried out on the chain, so that the information is open, transparent, traceable and tamper-proof, and the decentralized system ensures that the failure of a single node will not affect the security of the whole system; and the complaint process uses an asymmetric encryption method to ensure the safety and integrity of information transmission.
