1. A system for verifying the purported identity of a target individual comprising:

  • an enrollment database including sub-epidermal tissue optical spectra collected from at least one enrolled person, said enrolled person'"'"'s sub-epidermal tissue optical spectra having a plurality of measurement wavelengths obtained by applying a spectral band of optical wavelengths to said sub-epidermal tissue;

    means for obtaining at least one sub-epidermal tissue optical spectra and purported identity from said target individual, said target individual'"'"'s sub-epidermal tissue optical spectra having a plurality of measurement wavelengths obtained by applying said spectral band of optical wavelengths to sub-epidermal tissue of said target individual;

    means for comparing said target individual sub-epidermal tissue optical spectra and said enrolled person'"'"'s sub-epidermal tissue optical spectra by selecting for comparison a combination of individual wavelengths of said band emanating from said sub-epidermal tissue that are unique to said person and insensitive to environmental and instrumental effects, said enrolled person'"'"'s sub-epidermal tissue optical spectra corresponding to the purported identity of the target individual, said comparison providing a measure of the degree of similarity between said target individual sub-epidermal tissue optical spectra and said enrolled person'"'"'s sub-epidermal tissue optical spectra; and

    means for positively verifying said target individual'"'"'s identity by confirming that said target individual'"'"'s measure of spectral similarity is at least as similar as an established threshold value.
