MemCatalyst: Amplifying Data Auditing on Vision-Language Models via Data Poisoning

MemCatalyst is a set of data poisoning tools designed to improve data auditing for Vision‑Language Models (VLMs). It introduces two poisoning strategies—Poisoning Text and Poisoning Image—to force VLMs to over‑learn inconsistencies between image features and textual semantics, thereby increasing their vulnerability to membership inference attacks. Experiments on two prominent VLMs show that MemCatalyst significantly boosts MI AUC scores with a small number of poisoned samples while barely affecting overall model performance.
