The Center for Accelerating Operational Efficiency (CAOE) invites you to our latest seminar series Privacy Enhancing Technologies – Challenges, Opportunities, and Advancements. The next seminar features Dr. Steve Lu discussing Private Set Intersection – New constructions with applications to private linking and tracing.

About the Series

Privacy-enhancing technologies (PETs) under development promise the ability to control the sharing and use of sensitive information while minimizing the risk of unauthorized use. These technologies have been under development by researchers for nearly four decades but have been slow to migrate from the research lab into operational use. In this seminar series, Privacy Enhancing Technologies – Challenges, Opportunities, and Advancements we invite luminaries from across the globe to discuss the state-of-the-art in privacy enhancing technologies describing challenges, opportunities, and advancements with respect to technology development and uptake.

About the Seminar

Private Set Intersection (PSI) is one of the most useful and well-studied instances of secure computation, with many variants and applications. This seminar presents new solutions to PSI including a weighted and streaming variant in which the output is the sum of the weights of identifiers in the intersection. This has applications to privacy-preserving contact tracing, and ways to privately and continually search for matches between siloed data sources (such as in guest registries, visitor lists, flight manifests, and more).

Our protocols make use of a recent cryptographic breakthrough known as Function Secret Sharing to aggregate numerical payloads associated with the intersection while minimizing interaction and computational overhead. This enables simple and concretely efficient protocols for PSI, especially in the setting where one dataset is much smaller than the other (such as in personal contacts vs all infected persons). This presentation is based on our recent scientific publication that was part of a DARPA-funded effort.
