Abstract: A method for secure comparison of encrypted symbols. According to one embodiment, a user may encrypt two symbols, share the encrypted symbols with an untrusted third party that can compute algorithms on these symbols without access the original data or encryption keys such that the result of running the algorithm on the encrypted data can be decrypted to a result which is equivalent to the result of running the algorithm on the original unencrypted data. In one embodiment the untrusted third party may perform a sequence of operations on the encrypted symbols to produce an encrypted result which, when decrypted by a trusted party, indicates whether the two symbols are the same.
