Biometric identity verification system and method

摘要

A card authenticates a cardholder. The card includes a substrate, a sensor module, a wireless transceiver module, and a power circuit. The sensor module includes (a) a biometric sensor adapted to detect biometric information from a person's body, (b) a processor unit adapted to authenticate the person in response to the detected biometric information and generate an authentication signal representing an authentication result, and (c) a memory adapted to store biometric information of a specific individual associated with the card. The wireless transceiver module transmits signals received from the processor unit and receives a wirelessly-transmitted power signal. The power circuit generates at least one supply voltage from the received power signal and provides the supply voltage to the sensor module. An electronic passport is embedded with the card, and a terminal module is used for wirelessly transmitting power to and receiving signals from the electronic passport.

1. A wireless power authentication card associated with an owner comprising:
a power antenna adapted to wirelessly receive power from an external powering device; a biometric sensor; an authentication processor coupled to the biometric sensor and configured to authenticate the sensed biometric information, the authentication processor capable of being powered by the power antenna; a security transaction processor configured to receive an authentication signal from the authentication processor when the authentication processor authenticates the sensed biometric information, wherein the authentication processor terminates power to the security transaction processor after the security transaction processor receives the authentication signal from the authentication processor; and a signal antenna coupled to the security transaction processor, wherein the security transaction processor provides authentication information stored by the security transaction processor wirelessly via the signal antenna when power to the security transaction processor is terminated.
