AI Technical Summary
Existing technologies suffer from inefficiency and insufficient protection of client privacy in multi-database queries, especially when handling large-scale data queries and aggregation operations, which pose security risks.
This paper adopts a method that combines replication secret sharing with binary tree aggregation algorithm. It protects the query method through function secret sharing, realizes multi-party database query, and uses three-party computing parties to perform data operations. Each computing party does not need to be explicitly aware of the query-related operations, and combines replication secret sharing to protect the privacy of the data owner.
It significantly improves the privacy and security of multi-party database queries, shortens the waiting time for queryers, and enables efficient connection queries without disclosing sensitive information.
