We're excited to teach a Cybersafety class this quarter at UCR. In this first iteration, it'll be offered as a seminar class, but we will switch to a regular class next year. Preliminary syllabus: spalab.cs.ucr.edu/teaching/2… Looking forward to comments and feedback!

Huge congrats to @ganevgv for receiving the Distinguished Paper Award at #ieeesp25 @IEEESSP for his work "The Inadequacy of Similarity-based Privacy Metrics: Privacy Attacks against “Truly Anonymous” Synthetic Datasets." arxiv.org/pdf/2312.05114.pdf

.@ganevgv's paper, Understanding the Impact of Data Domain Extraction on Synthetic Data Privacy, will be presented at the ICLR SynthData workshop next week. A tiny paper studying the impact of how you extract the data domain while training generative models for synthetic data

Extracting it directly from the input data breaks DP. This well know but, alas, also common practice. Our experiments also show that membership inference attacks may perform well by detecting issues with data domain extraction rather than vulnerabilities of the generative models

TL;DR: 1/ We analyze 6 implementations of PATE-GAN, including 3 by the original authors 2/ None reproduce the utility reported in the original paper 3/ All implementations leak more privacy than intended 4/ We uncover 19 privacy violations and 5 other bugs

Tl;dr 1. We fail to replicate the utility performance reported in the original PATE-GAN paper across all the six implementations we benchmark; 2. All implementations leak more privacy than they should (empirical privacy estimates are worse than the theoretical DP bounds)
