Abstract

A method and apparatus for authenticating an identification of a person includes a portable computing device having a pair of imaging devices directed to a common location so as to generate a stereographic image of a subject. The portable computing device includes software for processing the image data to generate two dimensional and three dimensional biometric data of a person to be identified. The device is used to generate the biometric data for an identified person and then may be used to authenticate the identity of the person through comparison of newly acquired biometric data from the person to be identified to the previously acquired biometric data of the identified person.

Claims

1. A portable identity authentication apparatus, comprising:

a housing;

first and second imaging devices mounted in said housing, said first and second imaging devices being directed to a common point so as to image a subject in a stereographic manner;

a processor in said housing connected to receive image data from said first and second imaging devices; and

processing software operable on said processor so as to generate two dimensional and three dimensional biometric information on a person to be identified.

2. A portable identity authentication apparatus as claimed in claim 1, further comprising:

visible light and infrared light emitters mounted on said housing and directed toward the common point to which said first and second imaging devices are directed.

3. A method for authenticating an identity of a person to be identified, comprising the steps of:

obtaining a stereographic image of the person to be identified;

processing said stereographic image to generate two dimensional and three dimensional biometric data of the person to be identified;

comparing said two dimensional and three dimensional biometric data of the person to be identified to two dimensional and three dimensional biometric data of an identified person so that upon agreement of said biometric data an identity of the person is authenticated.
