摘要
稀有金属是国家的战略性资源,对其供应链信息的可追溯研究一直备受关注。针对稀有金属供应链面临的原料来源缺乏信任、监管难度大、信息共享效率低且缺乏隐私保护等问题,基于区块链设计了供应链产品信息可追溯系统。通过梳理和分析产业链业务环节以及存在的问题,设计了相关功能模块,提供了信息上链、可追溯信息查询等功能。采用多通道架构和隐私数据加密的设计用于隐私信息保护,保障了稀有金属供应链中产品数据的安全共享和信息可追溯。通过对原型系统的分析和测试,验证了系统的实际可行性和有效性。
Rare metals are a strategic resource of the country,and the traceability research of its supply chain information has always attracted much attention.In view of the lack of trust in the source of raw materials,the difficulty of supervision,the low efficiency of information sharing,and the lack of privacy protection faced by the rare metal supply chain,a supply chain product information traceability system was designed based on the blockchain.Through combing and analyzing the business links of the industry chain and existing problems,related functional modules are designed,and functions such as information uploading and traceable information query are provided.The design with multi⁃channel architecture and privacy data encryption is used for privacy information protection,ensuring the safe sharing of product data and information traceability in the rare metal supply chain.Through the analysis and testing of the prototype system,the actual feasibility and effectiveness of the system are verified.
