Private and Threshold Set-Intersection
Abstract
In this paper we consider the problem of privately computing the intersection of sets (set-intersection), as well as several variations on this problem: cardinality set-intersection, threshold set-intersection, and over-threshold set-intersection. Cardinality set-intersection is the problem of determining the size of the intersection set, without revealing the actual threshold number t times in the players' private inputs are revealed. Over-threshold set-intersection is a variation on threshold set-intersection in which not only the threshold set is revealed, but also the number of times each element in the threshold set appeared in the private inputs.
