基于Hyperledger Fabric的商品外包装设计产权保护模式

针对传统的中心化模式下外包装设计知识产权登记存在的数据易篡改、易泄露等安全问题和侵权问题，提出一种基于Hyperledger Fabric的商品外包装设计产权保护模式。以Hyperledger Fabric区块链为技术支撑，搭建去中心化、可溯源、内容不可篡改的联盟链网络，并融合星际文件系统（IPFS），提升区块链网络存储效能。同时运用所设计的多特征分层阈值检测的相似度鉴别算法模型，对商品外包装设计图像进行相似度检测。在保证设计作品原创性的前提下，调用智能合约对其进行上链确权，达到知识产权保护的目的。在包装企业、高校、研究机构等多方参与下应用此保护模式构建联盟链，对包装设计知识产权进行高效保护，这能促进包装设计产业健康发展。

Hyperledger Fabric Based Protected Mode for Property Rights of Commodity Packaging Design

Aiming at the security problems such as easy data tampering and leakage in the registration of intellectual property rights of packaging design under the traditional centralized mode and the infringement problems, a protected mode of commodity packaging design property rights based on Hyperledger Fabric blockchain was proposed. A decentralized, traceable, and tamper resistant alliance chain network was built with Hyperledger Fabric blockchain technology support, by integrating the Interplanetary File System (IPFS) to improve the storage efficiency of the blockchain network. Simultaneously by using the designed similarity discrimination algorithm model for multi feature layered threshold detection, similarity detection was performed on the product packaging design images. On the premise of ensuring the originality of the design work, the smart contract was called to confirm its rights on the chain, achieving the purpose of intellectual property protection. With the participation of packaging enterprises, universities, research institutions and other parties, this protection mode could be applied to build an alliance chain, effectively protect the intellectual property rights of packaging design, and promote the healthy development of the packaging design industry.
