Security Risks in FR Systems
Improved AdaBoost Algorithm
Adversarial Sample Generation
Facial recognition (FR) systems are increasingly deployed in critical applications like payment and identity verification, yet they face significant security challenges from adversarial sample (ASL) attacks. These attacks involve subtle, imperceptible perturbations to images that trick deep learning models into incorrect predictions. Such vulnerabilities can lead to authentication failures or identity errors, posing serious threats to system reliability and user trust. This research directly addresses these risks by developing advanced methods for ASL generation, aiming to improve the robustness of FR systems against such sophisticated attacks.
The core of our approach involves a significant enhancement to the traditional AdaBoost algorithm, a common facial detection method. We integrate Particle Swarm Optimization (PSO) for more efficient feature and threshold selection, and employ a dual-threshold classification method for improved data partitioning. This combination drastically reduces training time while maintaining high accuracy. The PSO-AdaBoost algorithm optimizes the selection of weak classifiers, creating a strong classifier that is both faster to train and more resilient against adversarial inputs compared to conventional methods.
Our integrated learning facial ASL generation algorithm, built upon the improved PSO-AdaBoost, aims to expose and mitigate vulnerabilities in existing biometric systems. By generating high-quality adversarial samples—images with imperceptible changes that fool FR models—we facilitate the development of more robust AI defenses. The algorithm successfully attacks a high percentage of facial images, demonstrating its effectiveness in creating realistic ASLs with high structural similarity (SSIM) and good perceptual quality (low LPIPS), enabling security professionals to better understand and fortify their FR systems.
