Abstract
Systems and methods for video backdoor attack include a trigger generation module for generating a universal adversarial trigger pattern specific to a task, an adversarial perturbation module for producing videos with manipulated features; and a poisoning and inference module for injecting the generated trigger into perturbed videos as poisoned samples for training; wherein the trigger pattern is patched and optimized on videos from all non-target classes but relabeled to a target class, and the trigger pattern is a universal adversarial trigger pattern generated by minimizing the cross-entropy loss.
