Abstract
Implementations of the present disclosure include methods, systems, and computer-readable storage mediums for receiving an encrypted first data set from a first entity, storing the encrypted first data set in computer-readable memory, receiving an encrypted second data set from a second entity, storing the encrypted second data set in computer-readable memory, receiving public encryption information associated with the encrypted first data set and the encrypted second data set, storing the public encryption information in computer-readable memory, and processing, using the one or more processors, the encrypted first data set and the encrypted second data set to provide the set intersection, wherein an advantage of a first adversary in guessing data elements of the encrypted first data set is negligible in a security parameter.
