Methods and devices for the secure encryption, enrollment, verification, and decryption of biometric and biographical identification information. The unique sequence of steps and the use of a combination of visible watermarking, invisible-fragile watermarking decoding, invisible-robust extraction, and decryption watermarking and encryption provides multiple layers of protection with four biometric based keys and makes it practically impossible for the information to be tampered with. |
