US Patent 11645406 System for verifying data access and method thereof

This application relates to a system for verifying data access and a method thereof. In one aspect, the system includes a service module for receiving a data access request for an original data from a client, and sending a first verification data to the client. The system also includes a verification module for receiving a first data eigenvalue corresponding to the original data from the service module, and generating a first verification fingerprint corresponding to the first data eigenvalue. The system further includes a data module for generating the first verification data by receiving the first verification fingerprint to embed into the original data, and generating a first integrity value by hashing the first verification data. The system further includes a verification database for storing data access information comprising the first data eigenvalue, the first verification fingerprint and the first integrity value in one record identified as the original data.
