- Abstract summary: Efforts have been made to add perturbations to protect images from diffusion-based mimicry pipelines.
Most of the existing methods are too ineffective and even impractical to be used by individual users.
We present novel findings on attacking latent diffusion models and propose new plug-and-play strategies for more effective protection.

- Abstract: While generative diffusion models excel in producing high-quality images,
they can also be misused to mimic authorized images, posing a significant
threat to AI systems. Efforts have been made to add calibrated perturbations to
protect images from diffusion-based mimicry pipelines. However, most of the
existing methods are too ineffective and even impractical to be used by
individual users due to their high computation and memory requirements. In this
work, we present novel findings on attacking latent diffusion models (LDM) and
propose new plug-and-play strategies for more effective protection. In
particular, we explore the bottleneck in attacking an LDM, discovering that the
encoder module rather than the denoiser module is the vulnerable point. Based
on this insight, we present our strategy using Score Distillation Sampling
(SDS) to double the speed of protection and reduce memory occupation by half
without compromising its strength. Additionally, we provide a robust protection
strategy by counterintuitively minimizing the semantic loss, which can assist
in generating more natural perturbations. Finally, we conduct extensive
experiments to substantiate our findings and comprehensively evaluate our newly
proposed strategies. We hope our insights and protective measures can
contribute to better defense against malicious diffusion-based mimicry,
advancing the development of secure AI systems. The code is available in

A novel arbitrary-in-arbitrary-out (AIAO) strategy makes watermarks resilient to fine-tuning-based removal.
Unlike the existing methods of designing a backdoor for the input/output space of diffusion models, in our method, we propose to embed the backdoor into the feature space of sampled subpaths.
Our empirical studies on the MS-COCO, AFHQ, LSUN, CUB-200, and DreamBooth datasets confirm the robustness of AIAO.

Backdoor attacks aim to surreptitiously insert malicious triggers into DNN models, granting unauthorized control during testing scenarios.
Existing methods lack robustness against defense strategies and predominantly focus on enhancing trigger stealthiness while randomly selecting poisoned samples.
We introduce a straightforward yet highly effective sampling methodology that leverages confidence scores. Specifically, it selects samples with lower confidence scores, significantly increasing the challenge for defenders in identifying and countering these attacks.

Federated Learning (FL) facilitates decentralized machine learning model training, preserving data privacy, lowering communication costs, and boosting model performance through diversified data sources.
FL faces vulnerabilities such as poisoning attacks, undermining model integrity with both untargeted performance degradation and targeted backdoor attacks.
We define a new notion of strong adaptive adversaries, capable of adapting to multiple objectives simultaneously.
MESAS is the first defense robust against strong adaptive adversaries, effective in real-world data scenarios, with an average overhead of just 24.37 seconds.
