When Anonymity Breaks: Identifying Models Behind Text-to-Image Leaderboards

CVPR 2026

Text-to-image (T2I) models are increasingly popular, producing a large share of AI-generated images online. To compare model quality, voting-based leaderboards have become the standard, relying on anonymized model outputs for fairness. In this work, we show that such anonymity can be easily broken.

Measuring memorization in language models via probabilistic extraction

NAACL 2025long

Large language models (LLMs) are susceptible to memorizing training data, raising concerns about the potential extraction of sensitive information at generation time. Discoverable extraction is the most common method for measuring this issue: split a training example into a prefix and suffix, then p…

Chameleon: Increasing Label-Only Membership Leakage with Adaptive Poisoning

ICLR 2024poster

The integration of Machine Learning (ML) in numerous critical applications introduces a range of privacy concerns for individuals who provide their datasets for ML training purposes. One such privacy risk is Membership Inference (MI), in which an adversary seeks to determine whether a particular dat…
