- Abstract: In recent years, many backdoor attacks based on training data poisoning have
been proposed. However, in practice, those backdoor attacks are vulnerable to
image compressions. When backdoor instances are compressed, the feature of
specific backdoor trigger will be destroyed, which could result in the backdoor
attack performance deteriorating. In this paper, we propose a
compression-resistant backdoor attack based on feature consistency training. To
the best of our knowledge, this is the first backdoor attack that is robust to
image compressions. First, both backdoor images and their compressed versions
are input into the deep neural network (DNN) for training. Then, the feature of
each image is extracted by internal layers of the DNN. Next, the feature
difference between backdoor images and their compressed versions are minimized.
As a result, the DNN treats the feature of compressed images as the feature of
backdoor images in feature space. After training, the backdoor attack against
DNN is robust to image compression. Furthermore, we consider three different
image compressions (i.e., JPEG, JPEG2000, WEBP) in feature consistency
training, so that the backdoor attack is robust to multiple image compression
algorithms. Experimental results demonstrate the effectiveness and robustness
of the proposed backdoor attack. When the backdoor instances are compressed,
the attack success rate of common backdoor attack is lower than 10%, while the
attack success rate of our compression-resistant backdoor is greater than 97%.
The compression-resistant attack is still robust even when the backdoor images
are compressed with low compression quality. In addition, extensive experiments
have demonstrated that, our compression-resistant backdoor attack has the
generalization ability to resist image compression which is not used in the
training process.
