AgentProv: Auditing Agentic LLM API Providers via Tool-use Policy Probes

Xun Wang, Bihe Zhao, Michael Backes +2

Commercial LLM APIs advertise a specific foundation model, but the served backbone may be silently substituted, quantized, or wrapped, for example to save deployment costs. All exi…

TabPATE: Differentially Private Tabular In-Context Learning Without Public Data

Dariush Wahdany, Matthew Jagielski, Jesse C. Cresswell +2

Tabular foundation models enable accurate in-context learning (ICL) from small labeled datasets, but the private records placed in context can leak through model predictions. We fi…

Dataset Usage Inference without Shadow Models or Held-out Data

Wojciech Łapacz, Stanisław Pawlak, Jan Dubiński +2

How much of my data was used to train a machine learning model? Dataset Usage Inference (DUI) aims to answer this by estimating what fraction of a dataset contributed to a model's…

Concept Removal for Frontier Image Generative Models

Aditya Kumar, Pierre Joly, Adam Dziedzic +1

Image generative models are trained on massive, largely uncurated internet-scale datasets that contain undesirable visual concepts. Efficiently removing such concepts from the mode…

Natural Identifiers for Privacy and Data Audits in Large Language Models

Lorenzo Rossi, Bartłomiej Marek, Franziska Boenisch +1

Assessing the privacy of large language models (LLMs) presents significant challenges. In particular, most existing methods for auditing differential privacy require the insertion…

MultiMem: Measuring and Mitigating Memorization in Multi-Modal Contrastive Learning

Wenhao Wang, Franziska Boenisch, Michael Backes +1

Memorization in machine learning models enables high performance on rare in-distribution samples by capturing their atypical patterns. However, it also causes harmful retention of…
