interpretation of differential privacy
- Authors: Georgios Kaissis, Jamie Hayes, Alexander Ziller, Daniel Rueckert
- Abstract summary: Reconstruction Robustness (ReRo) was recently proposed as an upper bound on the success of data reconstruction attacks against machine learning models.
Previous research has demonstrated that differential privacy (DP) mechanisms also provide ReRo, but so far, only Monte Carlo estimates of a tight ReRo bound have been shown.

- Abstract: We explore Reconstruction Robustness (ReRo), which was recently proposed as
an upper bound on the success of data reconstruction attacks against machine
learning models. Previous research has demonstrated that differential privacy
(DP) mechanisms also provide ReRo, but so far, only asymptotic Monte Carlo
estimates of a tight ReRo bound have been shown. Directly computable ReRo
bounds for general DP mechanisms are thus desirable. In this work, we establish
a connection between hypothesis testing DP and ReRo and derive closed-form,
analytic or numerical ReRo bounds for the Laplace and Gaussian mechanisms and
their subsampled variants.
