Control ControlNet: Multidimensional Backdoor Attack Based on ControlNet
摘要
Stable Diffusion (SD) has demonstrated remarkable performance in the realm of text2image generation. Furthermore, by appending additional conditions, such as the canny edge image, depth map and pose skeleton, can impose supplementary constraints on the generated images. Nevertheless, these conditions could render the model susceptible to subtle backdoor attacks. In this paper, we propose a backdoor attack method involving a hybrid injection strategy, which includes the first use of adversarial adjustments to text encoders and the first use of multi-dimensional composite triggers. Attackers can backdoor the ControlNet to generate various images they expected by injecting backdoors into the additional conditions and text prompts. In comparison to existing methods, the experimental results show our approach has greater levels of secrecy and semantic robustness. In the ablation study, we investigated the impact of using different dimension triggers and non-Adversarial text encoder on the evaluation metrics.
