Attacks and Defenses for Generative Diffusion Models: A Comprehensive Survey

Vu Tuan Truong, Luan Ba Dang, Long Bao Le

Abstract: Diffusion models (DMs) have achieved state-of-the-art performance on various generative tasks such as image synthesis, text-to-image, and text-guided image-to-image generation. However, the more powerful the DMs, the more harmful they can potentially be. Recent studies have shown that DMs are prone to a wide range of attacks, including adversarial attacks, membership inference attacks, backdoor injection, and various multi-modal threats. Since numerous pre-trained DMs are published widely on the Internet, potential threats from these attacks are especially detrimental to society, making DM-related security a topic worthy of investigation. Therefore, in this article, we conduct a comprehensive survey on the security aspect of DMs, focusing on various attack and defense methods for DMs. First, we present crucial knowledge of DMs with five main types of DMs, including denoising diffusion probabilistic models, denoising diffusion implicit models, noise conditioned score networks, stochastic differential equations, and multi-modal conditional DMs. We provide a comprehensive survey of recent works investigating different types of attacks that exploit the vulnerabilities of DMs. Then, we thoroughly review potential countermeasures to mitigate each of the presented threats. Finally, we discuss open challenges of DM-related security and describe potential research directions for this topic.
