SPECTROSCOPIC METHOD AND SYSTEM FOR MULTI-FACTOR BIOMETRIC AUTHENTICATION
First Claim
1. A multifactor authentication method comprising the steps of:
- acquiring a non-spectrometric biometric signature of a biometric signature source of a subject to be authenticated;
acquiring spectral information of the biometric signature source;
using the non-spectrometric biometric signature to determine the unique identity of the biometric signature source; and
using the spectral information to verify that the subject to be authenticated belongs to a predetermined class of objects.

Abstract
A multi-factor biometrics authentication method including the steps of: acquiring a non-spectrometric biometric signature (e.g. fingerprint, iris pattern, etc.) of a biometric signature source (e.g. fingertip, iris, etc.) of a subject to be authenticated (e.g. person); acquiring spectral information (e.g. diffuse reflectance spectrum, reflectance spectrum, etc.) of the biometric signature source; using the non-spectrometric biometric signature to determine the unique identity of the biometric signature source; and using the spectral information to verify that the subject to be authenticated belongs to a predetermined class of objects (e.g. living persons). A biometrics system (e.g. fingerprint authentication device, iris pattern authentication device) is augmented with spectral biometrics capability in a practical manner without introducing much overhead to the base biometrics technology or inconvenience to users.

14. A multifactor authentication system comprising:
-
a non-spectrometric biometric signature acquisition means for acquiring a non-spectrometric biometric signature of a biometric signature source of a subject to be authenticated; a spectral information acquisition means for acquiring spectral information of the biometric signature source; and an identity determination and verification means that uses the non-spectrometric biometric signature to determine the unique identity of the biometric signature source and uses the spectral information to verify that the subject to be authenticated belongs to a predetermined class of objects. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
