WPEC 2024 Talk 2a2: Measuring Demographic Disparities with Groupwise Private Set Intersection: A Federal Government Case Study

September 25, 2024

Tomo Lazovich - U.S. Census Bureau

Description

Abstract. With an increased focus on equity across the federal government, federal agencies and civil society have a need to join datasets with sensitive demographic data. Given legal, policy, and ethical constraints, the agencies that collect demographics cannot share them directly with such stakeholders in many cases. This presentation will show the application of Google's Private Join and Compute protocol to a public dataset of race and ethnicity information, enabling secure measurement of demographic disparities without explicit data sharing. We will describe the adaptations to open-source tools that were required to implement the protocol on government infrastructure. We will also illustrate potential use cases of the work that were ascertained through user interviews, including enabling third party audits of machine learning models. This presentation aims to be a primer on the practicalities of demonstrating a Privacy Enhancing Cryptography protocol on real infrastructure in a government setting.
