Abstract: Traditional copyright management methods rely on centralized servers for storage and verification, which leads to a series of problems, such as difficulty in detecting infringement, complexity in the copyright validation and authorization process, and the absence of an effective similarity retrieval mechanism. These issues make it difficult to provide copyright owners with credible evidence of their copyright. To address these challenges, this paper proposes an image digital copyright protection system based on Hyperledger Fabric blockchain network. The system integrates the scale-invariant feature transform (SIFT) similarity detection algorithm, discrete cosine transform (DCT) zero-watermarking algorithm, chaotic mapping image encryption algorithm, and inter planetary file system (IPFS) for distributed storage. System function tests and performance analyses demonstrate the system’s capability to achieve unique similarity detection, reliable copyright ownership proofs, decentralized encrypted storage, and seamless copyright transfer. These features collectively provide a transparent, safe and open platform for digital image copyright trading, ensuring effective copyright protection for copyright owners.

Key words: blockchain, scale-invariant feature transform(SIFT), discrete cosine transform(DCT)zero watermarking, chaotic mapping, image digital copyright
