Title: Taking the Hard Work Out of Privacy: Interactive Data Analysis with End-to-End Privacy Guarantees for All

Abstract:

We report on the design and implementation of the Privacy Integrated Queries (PINQ) platform for interactive privacy-preserving data analysis. PINQ is designed to expose an analysis language like SQL, allowing many data transformations and aggregations, but is carefully implemented to provide strong (and formal) differential privacy guarantees under arbitrary use. Importantly, the system itself provides the privacy guarantees, and does not require trust or expertise of the users, or privacy sophistication of the data providers. PINQ creates the potential to open statistical analysis of arbitrary sensitive data to arbitrary non-expert analysts, while still providing some of the strongest formal privacy guarantees possible. As well as describing PINQ, we give some examples of new analyses possible in its framework that have previously vexed privacy experts.
