Hyperledger Fabric-Based Copyright Management System for Clothing design drawings

The growth of the Internet has accelerated the distribution of digital content such as graphics and audio, and its copyright issues have gained attention. One particular industry worth noting, apparel design, has no explicit legal constraints, making piracy even easier. In this paper, we combine the decentralized and tamper-evident features of blockchain to design and implement a federated chain-based copyright management system for apparel design diagrams using the Hyperledger Fabric platform. In this paper, the copyright checking model uses perceptual hash algorithm and difference hash algorithm to calculate the graph similarity of garment effect and garment plan respectively, and calculate the mean value of similarity between them to determine whether they are plagiarized. The design diagrams are stored on IPFS, which makes up for the drawbacks of blockchain's difficulty in scaling and expensive storage space. Simulation experiments show that the blockchain system can maintain a high throughput and the originality checking model proposed in this paper can meet the practical requirements.
