New research suggests membership inference attacks may require more data than previously thought

A new research paper explores the sample complexity required for membership inference attacks, which aim to determine if an individual's data was used to train a machine learning model. The study, focusing on Gaussian mean estimation, suggests that attackers might need significantly more reference samples than the training algorithm itself uses to train the model. This finding challenges current practical attacks, which are limited to using a number of samples proportional to the training data size and may underestimate the potential for privacy breaches. AI

IMPACT This research highlights potential underestimation of privacy risks in current membership inference attack methods, suggesting a need for more robust defenses.

    The Sample Complexity of Membership Inference and Privacy Auditing

    arXiv:2508.19458v2 Announce Type: replace Abstract: A membership-inference attack gets the output of a learning algorithm, and a target individual, and tries to determine whether this individual is a member of the training data or an independent sample from the same distribution.…
