Use Procedural Noise to Achieve Backdoor Attack

Abstract

In recent years, more researchers pay their attention to the security of artificial intelligence. The backdoor attack is one of the threats and has a powerful, stealthy attack ability. There exist a growing trend towards the triggers is that the triggers become dynamic and global. In this paper, we propose a novel global backdoor trigger generated by procedural noise. Our backdoor triggers are much stealthy and straightforward to implement compared with most triggers. There are three types of procedural noise, and we evaluate the attack ability for the triggers with them on the different classification datasets, including CIFAR-10, GTSRB, CelebA, and ImageNet12.The experiment results show that our attack approach can bypass most defense approaches, even for the inspections of humans. We only need poison 5%-10% training data, and the attack success rate(ASR) can reach over 99%. To test the robustness of the backdoor model against the corruption methods that in practice, we introduce 17 corruption methods and compute the accuracy, attack success rate(ASR) of the backdoor model. The facts show that the backdoor models generated by our approaches have strong robustness for the most corruption methods and can be applied in reality.

Outlier Backdoor Attack Prevention Through Energy-Based Learning

“…Usually, according to the attacking target, the backdoor attack can be divided into three main categories: data set [4], platform [5] and model [19]. These three categories are not orthogonal to each other.…”
