FaceGuard: A Self-Supervised Defense Against Adversarial Face Images

no code implementations28 Nov 2020 Debayan Deb, Xiaoming Liu, Anil K. Jain

During training, FaceGuard automatically synthesizes challenging and diverse adversarial attacks, enabling a classifier to learn to distinguish them from real faces and a purifier attempts to remove the adversarial perturbations in the image space.
