AI Technical Summary
Existing methods for protecting facial image attributes suffer from poor versatility, lack of adaptive adjustment capabilities, and insufficient visual naturalness. They are difficult to adapt to various facial tampering attack models, and fixed perturbation parameters lead to unstable protection effects and an imbalance in image usability.
An adaptive adversarial face image attribute protection method is adopted. By introducing a natural loss function into the total loss function, the perturbation is dynamically adjusted using an adaptive PGD algorithm. The attack step size is optimized by combining momentum mechanism and SMAC algorithm, and image-level and model-level perturbation fusion is performed to achieve adaptive adjustment of adversarial perturbation and preservation of visual naturalness.
It achieves adaptive protection against various face tampering attack models, maintains the visual naturalness and usability of images, and improves the generalization ability and stability of the defense.
