摘要：Methods and apparatus for performing biometric determinations using optical spectroscopy of tissue (40). The biometric determinations that are disclosed include determination or verifications of identity, estimation of age, estimation of sex, determination of sample liveness and sample authenticity. The apparatuses disclosed are based upon discrete light sources (41,43,45,47,49,51) such as light emitting diodes, laser diodes, vertical cavity surface emitting lasers, and broadband sources with multiple narrow-band optical filters. The multiple light sources are encoded in a manner that the tissue response for each source can be efficiently measured. The light sources are prederably spaced at multiple distances from a detector (36) to contribute differing information to the biometric determination task as do light sources with different wavelength characteristics. Apparatuses are disclosed that incorporate a spectral biometric sensor with a personal electronic device such as cellular telephones, personal digital assistants, wristwatches, electronic fobs for the purpose of providing secure biometric access to protected property.
