Researchers have identified that cross-frame redundancy, rather than object trajectory, is the primary source of privacy leakage in video unlearning models. Current evaluation methods, which analyze frames individually, significantly underestimate this leakage. A new method called PACE has been developed to directly address this redundancy by using a permutation-invariant adversarial discriminator and a temporal consistency objective. PACE demonstrates strong privacy suppression on benchmark datasets like VSPW and Virtual KITTI~2 while maintaining usable model utility. AI
