Enterprise data privacy computation and secure sharing method and system

Abstract

The application provides an enterprise data privacy calculation and secure sharing method and system, relates to the technical field of enterprise data management, and first acquires an original enterprise data set and constructs an enterprise data hierarchical structure tree; performs a hierarchical obfuscation encryption operation on each hierarchical node to generate a hierarchical obfuscated data block; distributes the hierarchical obfuscated data block to different physical storage servers for distributed storage and generates a storage index table; after receiving a data sharing request, filters a candidate hierarchical obfuscated data block set according to a business hierarchical depth value; performs hierarchical relationship verification and joint decryption calculation on the candidate hierarchical obfuscated data block set to generate a shareable enterprise data view and returns the same. The application realizes secure sharing of enterprise data under the premise of privacy protection, reduces the risk of data leakage, and accurately controls the data sharing range.
