Visual Privacy Auditing with Diffusion Models

no code implementations12 Mar 2024 Kristian Schwethelm, Johannes Kaiser, Moritz Knolle, Daniel Rueckert, Georgios Kaissis, Alexander Ziller

We propose a reconstruction attack based on diffusion models (DMs) that assumes adversary access to real-world image priors and assess its implications on privacy leakage under DP-SGD.

Bounding Reconstruction Attack Success of Adversaries Without Data Priors

no code implementations20 Feb 2024 Alexander Ziller, Anneliese Riess, Kristian Schwethelm, Tamara T. Mueller, Daniel Rueckert, Georgios Kaissis

When training ML models with differential privacy (DP), formal upper bounds on the success of such reconstruction attacks can be provided.
