Apparatus and method for identification of individuals by near-infrared spectrum

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

• an authorized database including a plurality of intra-patient difference near-infrared tissue spectra for each of a plurality of authorized persons;
• means for obtaining a near-infrared tissue spectrum and purported identity from said target individual by applying a plurality of optical wavelengths to subepidermal tissue of the target individual and measuring a plurality of wavelengths emanating from the tissue;
• means for discriminating between said target individual near-infrared spectrum and said authorized persons near-infrared spectra by confirming consistency of a difference calculated between the target individual near-infrared spectrum and an authorization near-infrared tissue spectrum with the intra-patient difference near-infrared tissue spectra of the authorized database;
• and
• means for indicating if said target individual purported identity is correct.

A system for verifying the purported identify of a target individual comprising:

• a computer including an input device and an output device;
• a database including a plurality of intra-patient difference near-infrared tissue spectra for each of a plurality of authorized persons;
• means for obtaining a near-infrared tissue spectrum from said target individual, including a near-infrared radiation source for projecting a plurality of near-infrared optical wavelengths subcutaneously and a near-infrared spectrometer for measuring subcutaneous near-infrared intensity over a plurality of wavelengths;
• and
• a program running in said computer for discriminating between said target individual near-infrared spectrum and said authorized persons near-infrared spectra by confirming consistency of a difference calculated between the target individual near-infrared tissue spectrum and an authorization near-infrared tissue spectrum with the intra-patient difference near-infrared tissue spectra of the database.

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