Abstract
In order to address the issue of data privacy protection in facial recognition technology in the era of big data,a lightweight facial authentication scheme based on the SM4 algorithm for privacy protection was proposed.It utilized the FaceNet model to extract facial feature vectors and encrypted them using the SM4 algorithm,enhancing image encryp-tion efficiency.The p-stable LSH function was employed to quickly match the ciphertext values of facial features.Based on this,a new lightweight facial authentication protocol was designed.The security analysis indicats that the protocol can provide protection against replay attacks,data leakage,and anonymous authentication of user identities.Experimen-tal results show that the scheme achieves a significant improvement in computational and communication efficiency com-pared to homomorphic encryption.关键词
