Cert-LAS: Toward Certified Model Ownership Verification for Text-to-Image Diffusion Models via Layer-Adaptive Smoothing

ICML 2026poster

Large-scale text-to-image (T2I) diffusion models have enabled unprecedented creative applications, but their unauthorized use and reproduction have raised serious intellectual property concerns, making model ownership verification (MOV) increasingly critical. We find that existing backdoor-based dif…

Taught Well Learned Ill: Towards Distillation-conditional Backdoor Attack

NeurIPS 2025poster

Knowledge distillation (KD) is a vital technique for deploying deep neural networks (DNNs) on resource-constrained devices by transferring knowledge from large teacher models to lightweight student models. While teacher models from third-party platforms may undergo security verification (e.g., backd…

Towards Resilient Safety-driven Unlearning for Diffusion Models against Downstream Fine-tuning

NeurIPS 2025poster

Text-to-image (T2I) diffusion models have achieved impressive image generation quality and are increasingly fine-tuned for personalized applications. However, these models often inherit unsafe behaviors from toxic pretraining data, raising growing safety concerns. While recent safety-driven unlearni…
