Synthetic is all you need: removing the auxiliary data assumption for membership inference attacks against synthetic data

no code implementations4 Jul 2023 Florent Guépin, Matthieu Meeus, Ana-Maria Cretu, Yves-Alexandre de Montjoye

While membership inference attacks (MIAs), based on shadow modeling, have become the standard to evaluate the privacy of synthetic data, they currently assume the attacker to have access to an auxiliary dataset sampled from a similar distribution as the training dataset.

Achilles' Heels: Vulnerable Record Identification in Synthetic Data Publishing

no code implementations17 Jun 2023 Matthieu Meeus, Florent Guépin, Ana-Maria Cretu, Yves-Alexandre de Montjoye

The choice of vulnerable records is as important as more accurate MIAs when evaluating the privacy of synthetic data releases, including from a legal perspective.

Investigating the Effect of Misalignment on Membership Privacy in the White-box Setting

1 code implementation8 Jun 2023 Ana-Maria Cretu, Daniel Jones, Yves-Alexandre de Montjoye, Shruti Tople

We here present the first systematic analysis of the causes of misalignment in shadow models and show the use of a different weight initialisation to be the main cause.

QuerySnout: Automating the Discovery of Attribute Inference Attacks against Query-Based Systems

1 code implementation9 Nov 2022 Ana-Maria Cretu, Florimond Houssiau, Antoine Cully, Yves-Alexandre de Montjoye

We show the attacks found by QS to consistently equate or outperform, sometimes by a large margin, the best attacks from the literature.
