Noise Aggregation Analysis Driven by Small-Noise Injection: Efficient Membership Inference for Diffusion Models

Researchers have developed a novel membership inference attack against diffusion models that uses noise aggregation analysis and small-noise injection to determine whether specific data samples were included in training datasets. The method significantly reduces computational costs while improving accuracy compared to existing approaches, highlighting emerging privacy vulnerabilities in widely-deployed generative AI systems like Stable Diffusion.

Powerful Training-Free Membership Inference Against Autoregressive Language Models

Researchers have developed EZ-MIA, a training-free membership inference attack that dramatically improves detection of memorized data in fine-tuned language models by analyzing probability shifts at error positions. The method achieves 3.8x higher detection rates than previous approaches on GPT-2 and demonstrates that privacy risks in fine-tuned models are substantially greater than previously understood.

Assessing Per-Sample Membership Inference Vulnerability without Retraining

Researchers propose a novel method to assess individual training data vulnerability to membership inference attacks without requiring shadow models. The approach combines theoretical analysis in linear settings with a practical surrogate score for deep networks, using only geometry and loss information from a single trained model.
