PEPPER: Perception-Guided Perturbation for Robust Backdoor Defense in Text-to-Image Diffusion Models
PositiveArtificial Intelligence
- Recent advancements in text-to-image diffusion models have revealed vulnerabilities to backdoor attacks, prompting the introduction of PEPPER (PErcePtion Guided PERturbation), a novel defense mechanism that rewrites captions to disrupt harmful triggers while maintaining visual similarity. This method enhances robustness against attacks, particularly those targeting text encoders, and will be made available on GitHub.
- The implementation of PEPPER is significant as it not only reduces the success rate of backdoor attacks but also preserves the quality of generated content. This dual benefit positions PEPPER as a critical tool for developers and researchers working with text-to-image models, ensuring safer and more reliable outputs in various applications.
- The emergence of PEPPER highlights ongoing concerns regarding the security of AI-generated content, particularly in the context of multimodal models that integrate visual and textual data. As the field evolves, addressing vulnerabilities in generative models remains paramount, with approaches like PEPPER contributing to a broader discourse on the safety and ethical implications of AI technologies.
