Sequential Auditing for f-Differential Privacy
Tim Kutta, Martin Dunsche, Yu Wei +1
We present new auditors to assess Differential Privacy (DP) of an algorithm based on output samples. Such empirical auditors are common to check for algorithmic correctness and imp…
Pseudo-Equilibria, or: How to Stop Worrying About Crypto and Just Analyze the Game
Alexandros Psomas, Athina Terzoglou, Yu Wei +1
We consider the problem of a game theorist analyzing a game that uses cryptographic protocols. Ideally, a theorist abstracts protocols as ideal, implementation-independent primitiv…
The Normal Distributions Indistinguishability Spectrum and its Application to Privacy-Preserving Machine Learning
Yu Wei, Yun Lu, Malik Magdon-Ismail +1
We investigate the privacy of {\em any} algorithm whose outputs have Gaussian distribution. This work is motivated by the prevalence of such algorithms in several useful (ML) appli…
General-Purpose -DP Estimation and Auditing in a Black-Box Setting
Ãnder Askin, Holger Dette, Martin Dunsche +4
In this paper we propose new methods to statistically assess -Differential Privacy (-DP), a recent refinement of differential privacy (DP) that remedies certain weaknesses of…
