摘要:

人脸识别技术的广泛应用给人们带来了极大的便利,但也面临着身份等隐私信息被泄露的风险。针对人脸识别的攻击可通过重构人脸图像来获取原始图像的隐私信息,为防范此类攻击,提出了一种面向对抗样本干扰的人脸识别隐私保护方案(PPFR-ASP)。该方案采用频域技术中的协同推理机制,首先将人脸图像转换为频域特征,并分成高频成分特征和低频成分特征,然后在频域特征上添加对抗样本干扰。其次,为每个原始图像准备一个目标图像,对目标图像做和原始图像相同的频域特征转换处理,然后使用目标图像的频率成分通道遮盖原始图像中的相应成分,使攻击者将重构图像识别为目标图像,从而隐藏原始图像的真实身份。最后,文中所提方案在多个数据集上进行了大量的实验,结果表明其人脸图像隐私保护性能高于对比方案,查询精确度和计算开销与无隐私保护的ArcFace方案相接近。

Abstract:

While the wide application of face recognition technology brings great convenience to people,this technology also faces the risk of identity and other private information being leaked.Some current attacks against face recognition can obtain the privacy information on the original image by reconstructing the face image.To prevent such attacks,this paper proposes a privacy-preserving face recognition model against adversarial sample perturbation(PPFR-ASP).Specifically,our scheme employs collaborative inference in the frequency domain.First,the face image is transformed into frequency domain features,which are divided into high-frequency and low-frequency components.Then we add adversarial sample perturbation on the frequency domain features.Furthermore,a target image is prepared for each original image,and the same frequency domain feature transformation is applied to the target image.The frequency component channels of the target image are used to mask the corresponding components in the original image so as to cause the attacker to reconstruct the image as the target image,thereby concealing the true identity of the original image.Finally,extensive experiments are conducted on multiple datasets,demonstrating that the privacy protection performance of this solution for facial image data exceeds that of comparative approaches.The query accuracy and computational overhead of this solution are comparable to those of the unprotected ArcFace scheme.

Key words: face recognition, privacy-preserving, frequency domain technique, adversarial sample perturbations
