On the Inadequacy of Similarity-based Privacy Metrics: Reconstruction Attacks against "Truly Anonymous Synthetic Data''

no code implementations8 Dec 2023 Georgi Ganev, Emiliano De Cristofaro

Alas, this is not the standard in industry as many companies use ad-hoc strategies to empirically evaluate privacy based on the statistical similarity between synthetic and real data.

Privacy Preserving Reconstruction Attack

On the Challenges of Deploying Privacy-Preserving Synthetic Data in the Enterprise

no code implementations9 Jul 2023 Lauren Arthur, Jason Costello, Jonathan Hardy, Will O'Brien, James Rea, Gareth Rees, Georgi Ganev

Generative AI technologies are gaining unprecedented popularity, causing a mix of excitement and apprehension through their remarkable capabilities.

Privacy Preserving

When Synthetic Data Met Regulation

no code implementations1 Jul 2023 Georgi Ganev

In this paper, we argue that synthetic data produced by Differentially Private generative models can be sufficiently anonymized and, therefore, anonymous data and regulatory compliant.

Understanding how Differentially Private Generative Models Spend their Privacy Budget

no code implementations18 May 2023 Georgi Ganev, Kai Xu, Emiliano De Cristofaro

Generative models trained with Differential Privacy (DP) are increasingly used to produce synthetic data while reducing privacy risks.

dpart: Differentially Private Autoregressive Tabular, a General Framework for Synthetic Data Generation

2 code implementations12 Jul 2022 Sofiane Mahiou, Kai Xu, Georgi Ganev

We propose a general, flexible, and scalable framework dpart, an open source Python library for differentially private synthetic data generation.

DP-SGD vs PATE: Which Has Less Disparate Impact on GANs?

no code implementations26 Nov 2021 Georgi Ganev

Generative Adversarial Networks (GANs) are among the most popular approaches to generate synthetic data, especially images, for data sharing purposes.

Robin Hood and Matthew Effects: Differential Privacy Has Disparate Impact on Synthetic Data

no code implementations23 Sep 2021 Georgi Ganev, Bristena Oprisanu, Emiliano De Cristofaro

We analyze the impact of DP on these models vis-a-vis underrepresented classes/subgroups of data, specifically, studying: 1) the size of classes/subgroups in the synthetic data, and 2) the accuracy of classification tasks run on them.

On Utility and Privacy in Synthetic Genomic Data

no code implementations5 Feb 2021 Bristena Oprisanu, Georgi Ganev, Emiliano De Cristofaro

The availability of genomic data is essential to progress in biomedical research, personalized medicine, etc.
