Compiling Python Programs into Differentially Private Ones

Thursday, June 23, 2022 - 10:30 am10:45 am

Johan Leduc and Nicolas Grislain, Sarus Technologies


Working with privacy-sensitive data today, whether it is in health-care, insurance or any other industry, is a complex and slow process often involving long manual reviews by compliance teams. The recent development of differential privacy helped standardize what privacy protection means. As such it has the potential to unlock the automation and scaling of data analysis on privacy sensitive data. To help realize this promise, we designed and built a framework in which an analyst can write data analysis jobs with common data-science tools and languages: SQL, numpy, pandas, scikit-learn, and have them compiled into differentially private jobs executed remotely on the sensitive data. In this talk, we will describe how a user expresses his job declaratively in python and how his python code is analyzed and compiled, before it is run and a result is eventually returned.
