DP-Opt

An enhanced disprover algorithm which aims to resolve the limitations in counterexample construction of the latest work DP-Sniper and produce higher privacy violations.

Install

pip install -r requirements.txt

We used python version 3.8 to run our evaluations.

Basic Usage

To run the evaluation, run the following command:

python dpopt/experiments/__main__.py

The main algorithms DP-Opt and PowerSearcher from the paper can be found in dpopt/search/powersearcher.py and

dpopt/attack/dpopt.py.
