Without revealing the original data and business privacy, Privacy Computing allows multiple parties to collaboratively compute and analyze data through encrypted mechanisms，achieving the value of data integration. However, there are issues such as weak protection of data security, lack of identity authentication mechanisms, and absence of privacy protection during data discovery and authorization processes.

Privacy Computing combined with blockchain technology, will provide a decentralized data platform , allowing data owners to register their data on the blockchain and define the attributes and access rules of the data through smart contracts. Data users can discover datasets that meet their needs through identity authentication and access control mechanisms on the blockchain’s data directory and search functions, ensuring the integrity of data throughout the entire computing access process.
