An optical security system using phase encryption of biometric identification data is demonstrated. For this effort, fingerprints are used as the biometric signature. Two types of phase masks are fabricated: photopolymer film and polyimide film. The masks containing the phase-encrypted fingerprints are tested using a joint transform optical correlator. The results of the tests demonstrate that the encryption methods are successful, as the target fingerprint is recognized and the test print is rejected.
