Query: Imperceptible and Multi-channel Backdoor Attack against Deep Neural
  Networks   Recent researches demonstrate that Deep Neural Networks (DNN) models are
vulnerable to backdoor attacks. The backdoored DNN model will behave
maliciously when images containing backdoor triggers arrive. To date, existing
backdoor attacks are single-trigger and single-target attacks, and the triggers
of most existing backdoor attacks are obvious thus are easy to be detected or
noticed. In this paper, we propose a novel imperceptible and multi-channel
backdoor attack against Deep Neural Networks by exploiting Discrete Cosine
Transform (DCT) steganography. Based on the proposed backdoor attack method, we
implement two variants of backdoor attacks, i.e., N-to-N backdoor attack and
N-to-One backdoor attack. Specifically, for a colored image, we utilize DCT
steganography to construct the trigger on different channels of the image. As a
result, the trigger is stealthy and natural. Based on the proposed method, we
implement multi-target and multi-trigger backdoor attacks. Experimental results
demonstrate that the average attack success rate of the N-to-N backdoor attack
is 93.95% on CIFAR-10 dataset and 91.55% on TinyImageNet dataset, respectively.
The average attack success rate of N-to-One attack is 90.22% and 89.53% on
CIFAR-10 and TinyImageNet datasets, respectively. Meanwhile, the proposed
backdoor attack does not affect the classification accuracy of the DNN model.
Moreover, the proposed attack is demonstrated to be robust to the
state-of-the-art backdoor defense (Neural Cleanse).
