Aiming at the problems of data security and credibility in master data management, this paper proposes a master data management method and system design that takes advantage of the decentralized, tamper-proof and traceable features of blockchain. Aiming at the privacy and security problems of data sharing, this paper combines symmetric encryption algorithm with attribute-based encryption algorithm to achieve fine-grained access control of data. At the same time, the blockchain technology is combined with distributed storage, and only data, hash index, access control policy and other information are stored on the blockchain, which greatly reduces the storage pressure of blockchain nodes.
