Researchers have developed and compared four distinct methods for auditing the differential privacy guarantees of image-to-image face generation systems. These methods, including a Gaussian mechanism approach, kernel density log-ratio, maximum mean discrepancy, and hypothesis testing, were applied to the FaceFusion and InstantID models. The study revealed significant identity distinguishability in the generated images across all tested methods, though the reported privacy parameter estimates varied considerably due to each method's unique assumptions and finite-sample limitations.
