Scene

This repository aims to simulate the application of fully homomorphic encryption (FHE) technique on criminal database. We will demonstrate how to use FHE technique to perform various database operations without decrypting the criminal data, such as counting the number of crimes or querying specific criminal data based on encrypted names.
