New TRACE Method Detects Backdoors in Object Detection Models

Researchers have developed a new method called TRACE (TRAnsformation Consistency Evaluation) to detect poisoned samples in object detection models at test time. This technique addresses the unique challenges posed by object detection, where current defenses are insufficient against attacks that can cause "ghost" objects or make objects vanish. TRACE leverages the observation that poisoned samples exhibit more consistent detection results across varied backgrounds and different focal information compared to clean samples. By assessing transformation consistency through object confidence variance, TRACE offers black-box, universal backdoor detection and has shown a 30% improvement in AUROC over existing methods, while also demonstrating resistance to adaptive attacks.
