Optical pattern recognition for validation and security verification

摘要: We propose an idea for security verification of credit cards, passports, and other forms identification so that they cannot easily be reproduced. A new scheme complex phase/amplitude patterns seen copied by intensity-sensitive detector such as a CCD camera is used. The basic to permanently irretrievably bond phase mask primary amplitude pattern fingerprint, picture face, or signature. Computer simulation results tests the proposed system are provided verify both separately readable identifiable in optical processor correlator.
