Secure face recognition algorithm based on full homomorphic encryption

Abstract： Face recognition technology is an important topic in computer vision research and has a wide range of application prospects in the field of biometric authentication. However, the ease of access to face images has led to their misuse and causes privacy leakage, so there is an increasing concern about the privacy of users′ face images from all walks of life. In this paper, we proposed a face recognition algorithm based on full homomorphic encryption, which can effectively protect the privacy of user face images and ensure that the server does not learn any information about user images when providing face recognition services. The experimental results show that the algorithm in this paper is more secure and the computational efficiency is also improved.
