1. An access control system, comprising:
- a surface acoustic wave sensor which outputs a signal indicative of a distorted print; and
a processor which compares the distorted print signal to one or more identity patterns and controls access to a restricted item based on results of said comparison.

Abstract
An access control method achieves enhanced security and accuracy compared with other systems through recognition of one or more distorted biometrics. The method includes outputting a distorted biometric print from a surface acoustic wave (SAW) device into an identification system, comparing the distorted print to one or more distortion patterns, and controlling access to a restricted item based on results of the comparison. The distorted print maybe formed based on a transfer function or excitation frequency of the SAW device, or may be formed by a mask pattern located on or between a sensing surface of the SAW device. The print may be a fingerprint, thumb print, and palm print.

33. An identification method, comprising:
-
combining two degrees of uniqueness, wherein the first degree of uniqueness is a print and the second degree of uniqueness is a print modifier; and
determining an identity of the print based on the combined degrees of uniqueness.
