JPEG Compression-Resistant Low-Mid Adversarial Perturbation against Unauthorized Face Recognition System
share
It has been observed that the unauthorized use of face recognition system raises privacy problems. Using adversarial perturbations provides one possible solution to address this issue. A critical issue to exploit adversarial perturbation against unauthorized face recognition system is that: The images uploaded to the web need to be processed by JPEG compression, which weakens the effectiveness of adversarial perturbation. Existing JPEG compression-resistant methods fails to achieve a balance among compression resistance, transferability, and attack effectiveness. To this end, we propose a more natural solution called low frequency adversarial perturbation (LFAP). Instead of restricting the adversarial perturbations, we turn to regularize the source model to employing more low-frequency features by adversarial training. Moreover, to better influence model in different frequency components, we proposed the refined low-mid frequency adversarial perturbation (LMFAP) considering the mid frequency components as the productive complement. We designed a variety of settings in this study to simulate the real-world application scenario, including cross backbones, supervisory heads, training datasets and testing datasets. Quantitative and qualitative experimental results validate the effectivenss of proposed solutions.
