Biometric authentication system
DCFirst Claim
1. A biometric authentication apparatus, comprising:
- a smart card having;
a computer chip storing data corresponding to a biometric feature of a card user, the smartcard adapted for providing the biometric feature data for comparison to the biometric feature of the card user, a non-biometric identifier corresponding to the card user; and
a portable reader having;
a housing, the housing having an inlet constructed and arranged for releasably receiving the smart card at the housing, a biometric scanner mounted to the housing and accessible to the biometric feature of the card user, a central processing unit (CPU) mounted to the housing, the CPU adapted for comparing at the portable reader the biometric feature at the scanner with the biometric feature data stored on the computer chip of the smart card for generating a first comparison signal representing the authentication status of the card user, and for providing a second comparison when the first comparison signal indicates positive authentication of the user, the second comparison between the non-biometric identifier of the smart card and other user data stored remote from the smart card to further determine authentication status of the user and generate a second comparison signal;
a control chip associated with the CPU at the portable reader, the control chip preventing communication with the authentication apparatus until positive authentication of the user is complete; and
an indicator assembly adapted for receiving the first and second comparison signals generated to indicate the authentication status of the card user.

Abstract
A biometric authentication system is provided which includes a dual input reader, the inputs consisting of stored physiological data of a user on a chip disposed on a smart card, and a fingerprint scan for comparison against the stored data. The system is self-contained so that the comparison of the biometric data with the data stored on the chip is done immediately on board the reader without relying upon communications to or from an external source in order to authenticate the user. The invention also prevents communication with external sources prior to user authentication being confirmed, so as to prevent user data from being stolen or corrupted. Alternatively, the biometric input can consist of a retina scan, voice identification, saliva or other biometric data.
