System and method for performing security access control based on modified biometric data

A computer-readable medium storing an access control program, comprising:

• a first code section which compares a distorted biometric received by an input unit to one or more distortion patterns;
• and
• a second code section which controls access to a restricted item based on results of the comparing step.

An access control system, comprising:

• a receiver which receives a signal indicative of a combination of two or more unique identity attributes, at least one of the unique identity attributes corresponding to a biometric of a person;
• and
• a processor which compares the signal to one or more identity patterns and controls access to a restricted item based on results of said comparison.

An access control system, comprising:

• a receiver which receives a biometric modified by a predetermined distortion pattern;
• and
• a processor which compares the distorted biometric to one or more identity patterns and controls access to a restricted item based on results of said comparison.

An access control system, comprising:

• a receiver which receives a modulated biometric;
• and
• a processor which compares the modulated biometric to one or more identity patterns and controls access to a restricted item based on results of said comparison.

An access control system, comprising:

• a receiver which receives an encoded biometric;
• and
• a processor which compares the encoded biometric to one or more identity patterns and controls access to a restricted item based on results of said comparison.
