Abstract
This paper proposes a secure, reliable and collaborative data-sharing system for China’s housing provident fund based on blockchain. Firstly, federal computing was introduced to realize “available but invisible” sharing of data about housing provident fund, which reduces the data leakage risk and improves the data availability. Secondly, four data sharing modes were proposed to deal with different situations with different amount of data provider and data. Lastly, to realize individual data deep sharing on the premise of security, an enterprise and personal information query authorization mechanism was established to provide solutions to personal and institutional authorization. This system helps to realize both the internal and external data sharing of the housing provident fund system under the premise of security and privacy protection. This system improves the efficiency of housing provident fund issue, and fully taps the value of data comprehensively.
