1. A method of performing a biometric identification, the method comprising:

  • illuminating a small-area of a finger of an individual with illumination light from an illumination source;

    receiving, at a sensor, light scattered from the small-area of the finger;

    generating, with a processor, a local feature profile from the received light, wherein the local feature profile identifies a feature of the small-area of the finger, the feature of the small-area of the finger being of a type predetermined to exhibit substantial local consistency; and

    analyzing, with a processor, the generated local feature profile to perform the biometric identification,wherein analyzing the generated local feature profile comprises comparing the generated local feature profile with a reference local feature profile,wherein the reference local feature profile was generated from light scattered from a small-area reference skin site, andwherein the small-area of the finger is from a substantially different portion of the finger than the small-area reference skin site.
