We describe a protocol to solve the problem of comparing fingerprints without actually exchanging them. We extend this to private verification where the verifier does not obtain fingerprint information. We show that no substantial information is leaked to the other party even during multiple protocol runs and present evaluation results from a prototype implementation.
