Abstract: Indistinguishable adversarial attacks have been demonstrated with the sophistication of adversarial machine learning for neural networks. One example of such advanced algorithms is the backdoor attack with hidden triggers proposed by Saha et al. While Saha’s backdoor attack can produce invisible and dynamic triggers during the training phase without mislabeling, visible patch images are appended during the inference phase. A natural question is whether there exists a clean label backdoor attack whose trigger is dynamic and invisible at all times. In this study, we answer this question by adapting Saha’s backdoor attack to the trigger generation algorithm and by presenting a completely invisible backdoor attack with dynamic triggers and correct labels. Experimental results show that our proposed algorithm outperforms Saha’s backdoor attacks in terms of both indistinguishability and the attack success rate. In addition, we realize that our backdoor attack is a generalization of adversa rial examples since our algorithm also works by using poisoning data only during the inference phase. We also describe a concrete algorithm for reconstructing adversarial examples as clean-label backdoor attacks. Several defensive experiments are conducted for both algorithms. This paper discovers the close relationship between hidden trigger backdoor attacks and adversarial examples. (More)
