摘要
供应链上各参与主体间的数据共享与合作是供应链金融机制运行的重要基石。区块链、隐私计算等技术的引入,从一定程度上解决了金融数据共享的安全性与隐私保护的矛盾,但仍存在区块链数据存储效率低,资源消耗巨大、数据合作中存在多数据源一致性以及计算结果正确性验证等问题。在对主流技术架构研究的基础上,提出了基于区块链技术的供应链金融隐私保护模型FDP,该模型搭建智能合约将金融关键数据(FKD)存储于Fisco Bcos3.0,金融文件数据(FFD)存储于IPFS的“双链”模式,解决数据在区块链上的存储性能问题;通过隐私计算中间件管理供应链金融多方的数据共享合作,通过划定可信数据计算第三方安全域,获取多源数据授权使用,通过需求方加密算法完成计算任务并保证任务算法计算结果的正确性与安全性。实验证明,FDP模型在提升数据存储、查询效率的同时解决数据合作的隐私安全问题。
Data sharing and collaboration in the supply chain are crucial foundations for the supply chain finance.The intro-duction of technologies such as blockchain and privacy computing has,to some extent,resolved the contradiction between the secu-rity of financial data sharing and privacy protection.However,issues such as low data storage efficiency,massive resource consumption,data consistency across multiple sources,and verification of calculation result accuracy still persist.Based on the research of technology architectures,a blockchain-based supply chain financial privacy protection model FDP is proposed.This model builds smart contracts to store financial key data(FKD)on Fisco Bcos3.O and financial document data(FFD)on IPFS in a "dual-chain" mode,addressing data storage performance issues on the blockchain.Through privacy computing middleware,it manages data sharing cooperation among multiple parties in supply chain finance.By defining trusted data computing third-party security domains,it obtains authorization for multi-source data usage.It completes computational tasks through demand-side encryption algorithms while ensuring the correctness and security of task algorithm results.Experiments demonstrate that the FDP model improves data storage and query efficiency while solving privacy and security issues in data collaboration.
