Abstract
Systems, methods, devices, and other techniques for preserving privacy when comparing private datasets from first and second computing systems. The second computing system identifies a first set of identifiers corresponding to records in a private database of the second computing system. The second computing system receives blinded versions of a set of identifiers corresponding to records in a private database of the first computing system. The second computing system determines an intersection or characteristic thereof of the records in the private database of the first computing system and the records in the private database of the second computing system based on matches between the blinded versions of the first and second sets of identifiers.
