摘　　要：为实现正确身份认证的同时保障用户个人隐私安全,提出了基于边缘计算的人脸身份认证系统中的隐私保护技术。在人脸身份认证隐私保护系统的注册阶段,采用双随机相位加密算法对彩色人脸图像进行加密,同时利用卷积神经网络提取人脸图像特征,采用秘密分享同态技术对提取到的人脸特征向量进行加密并存储,实现其隐私保护;在认证阶段,系统会从边缘计算节点获取用户的人脸图像特征向量,协同多个边缘计算节点,采用基于秘密分享同态的隐私保护技术完成人脸身份认证,权限分配机构为认证通过用户下发访问权限。实验结果显示,该技术可有效保障用户的隐私安全,降低人脸信息泄露风险,并准确无误地完成人脸身份认证,拒绝非法访问和人脸图像窃取。This paper studies the privacy protection technology in the face identity authentication system based on edge computing,which can achieve correct identity authentication and protect the privacy of users.During the registration phase of the facial identity authentication privacy protection system,convolutional neural networks are used to extract facial image features,and a double random phase encryption algorithm is used to encrypt colored facial images.At the same time,use convolutional neural networks to extract face image features from part of the sparse decrypted face images as input,encrypt and store the extracted facial feature vectors using secret sharing homomorphic techniques,achieving privacy protection;In the authentication phase,the system will obtain the user’s face image feature vector from the edge computing node,cooperate with multiple edge computing nodes,and use privacy protection technology based on secret sharing homomorphism to complete the face identity authentication.The authority will issue access permissions to the authenticated users.The experimental results show that this technology can effectively ensure the privacy and security of users,reduce the risk of facial information leakage,and accurately complete facial identity authentication,rejecting illegal access and facial image theft.
