Abstract
A third party cryptographically determines a private set difference between a data set of a first party and a data set of a second party. The third party cryptographically generates a key pair including a private key and a public key, provides the public key to the first party and the second party, receives an encrypted result from the second party, wherein the encrypted result is computed prior to receipt by the third party using homomorphic operations performed using the public key, the data set of the first party, and the data set of the second party, decrypts the encrypted result using the private key to yield an intermediate data set, and determines the private set difference between the first data set and the second data set based on the intermediate data set.
