Privacy concerns may discourage users who would otherwise join beneficial data mining tasks for intelligence and/or security. We propose an efficient protocol that allows parties to share data in a private way with no restrictions and without loss of accuracy. Our method has the immediate application that horizontally partitioned databases can be brought(More)
