Research on the Application of Blockchain in the Safe and Trusted Sharing of Government Data

To avoid the security vulnerabilities and privacy leakage risks in the process of government data sharing, a data sharing scheme for government data based on blockchain is proposed in this paper. As one of the basic protocols for the next generation of global credit authentication and value Internet, blockchain technology has been paid more and more attention. The blockchain is used to realize data tamper-proof, distributed storage, privacy protection, traceability, and access control. Data sharing and exchange agreements between government public services have adopted blockchain technology, providing identity authentication and message permission management. Using the blockchain to record the sharing behavior and provide traceability, the smart contract is used to share and manage the data and ensure the data’s consistency on-chain and off-chain. Due to shortcomings of government data sharing, the paper designs a data-sharing scheme and technical framework based on blockchain technology. From its perspective, it takes housing provident fund data sharing, for example, to establish a provident fund chain in the industry. This blockchain application scenario has been applied to the housing provident fund industry, forming a new model of industry data sharing.
