First Claim
1. A method for identifying an individual, the method comprising:
- propagating electromagnetic radiation into tissue of the individual;
receiving a measured spectral variation in the form of electromagnetic radiation scattered from the tissue of the individual; and
comparing the measured spectral variation with a previously stored spectral variation over a predetermined wavelength interval by comparing, at each of a plurality of wavelengths within the predetermined wavelength interval, a property of the measured and previously stored spectral variations that is independent of a presence of other wavelengths; and
designating the individual as having an identity associated with the previously stored spectral variation if the measured spectral variation is consistent with the previously stored spectral variation.

Abstract
Methods and systems are provided for identifying an individual. Electromagnetic radiation is propagated into tissue of the individual. A measured spectral variation is received in the form of electromagnetic radiation scattered from the tissue of the individual. The measured spectral variation is compared with a previously stored spectral variation over a predetermined wavelength interval. The comparison is performed at each of multiple wavelengths within the predetermined wavelength interval and is performed of a property of the measured and previously stored spectral variations that is independent of a presence of other wavelengths. The individual is designated as having an identity associated with the previously stored spectral variation if the measured spectral variation is consistent with the previously stored spectral variation.
