A Novel Fragile Zero-watermarking Algorithm Based on Quaternion and LBP under the Background of Blockchain
Feng Liu · 2023
After the emergence of blockchain technology, although the problem of copyright protection on the chain has been solved, the problem of cross-chain prosecution and confirmation protection has not been solved.Zero watermarking is a technique that achieves copyright protection without any modification to the carrier image. This paper proposes a fragile zero-watermarking algorithm based on quaternion and LBP.In this way, the joint blockchain and fragile zero-watermark technology can solve the problem of cross-chain prosecution and confirmation protection.
