Abstract

Methods and apparatuses for performing biometric determinations using optical spectroscopy of tissue. 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 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 spaced at multiple distances from a detector 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.

Claims

1. A personal identification system for performing biometric determination tasks to enable access to protected property, comprising:

a personal device;

a spectral biometric sensor;

means for processing the resulting spectral data to perform a biometric determination; and

means to authorize access or deny access to the protected property in accordance with the results of the biometric determination.

2. A system as recited in claim 1, wherein the personal device is a personal digital assistant.

3. A system as recited in claim 1, wherein the personal device is a cellular telephone.

4. A system as recited in claim 1, wherein the personal device is a wristwatch.

5. A system as recited in claim 1, wherein the personal device is an electronic fob.

6. A system as recited in claim 1, wherein the personal device is a smart card.

7. A system as recited in claim 1, wherein the personal device is a firearm.

8. A method for limiting access to protected property using a biometric sensor comprising steps of:

collecting biometric enrollment data from known unauthorized people;

collecting target biometric data from target people;

comparing said target biometric data to said unauthorized enrollment data; and

denying access to said protected property if match between said target biometric data and said unauthorized enrollment data is determined.

9. The method recited in claim 8, wherein said biometric sensor is a spectral biometric sensor.

10. The method recited in claim 8, wherein said protected property is a weapon.

11. The method recited in claim 10, wherein said weapon is a firearm.
