Psi privacy set intersection

WebJul 9, 2024 · As a reminder, PSI is where each of two parties has a set of elements, and one or both of them want (s) to discover the intersection between those sets (a) without revealing anything other than the intersection to each other, and (b) without revealing anything sensitive about their sets to an eavesdropper. WebJun 30, 2015 · Private Set Intersection (PSI) allows two parties to compute the intersection of private sets while revealing nothing more than the intersection itself. PSI needs to be applied to large data sets in scenarios such as measurement of ad conversion rates, data sharing, or contact discovery.
