BIOMETRIC IDENTIFICATION APPARATUS
First Claim
1. A biometric identification apparatus, comprising a control module, a fingerprint identification module, a pulsatile blood flow detection module and a holder body, wherein;
- said control module is electrically connected to said fingerprint identification module and said pulsatile blood flow detection module and adapted for controlling said fingerprint identification module and said pulsatile blood flow detection module to start detection, receding detected feedback signals from said fingerprint identification module and said pulsatile blood flow detection module and using the data of said detected feedback signals for analysis and matching through a microprocessor thereof;
said fingerprint identification module comprises a fingerprint scan controller controllable by said microprocessor of said control module to generate a scan control signal, and a fingerprint receiver adapted for receiving signals from said fingerprint scan controller and transmitting received signals to said microprocessor of said control module;
said pulsatile blood flow detection module comprises at least one light source controllable by said microprocessor of said control module to emit light, and at least one photo detector adapted for receiving light and outputting signals to said microprocessor of said control module;
said holder body covered over said fingerprint identification module and said pulsatile blood flow detection module at a top side, said holder body comprising a fingerprint identification zone and a pulsatile blood flow identification zone arranged adjacent to each other at a top side thereof, the combined surface area of said fingerprint identification zone and said pulsatile blood flow identification zone being approximately equal to the surface area of the finger pad of one single finger of a human being;
wherein when a user places the fingertip of one single finger thereof on said fingerprint identification zone and said pulsatile blood flow identification zone, said fingerprint identification module detects the fingerprint of said finger and provides the detected fingerprint signal to said control module, said pulsatile blood flow detection module detects a fingertip pulsatile blood flow signal from said finger and provides the detected fingertip pulsatile blood flow signal to said control module;
said control module receives said fingerprint signal from said fingerprint identification module and said fingertip pulsatile blood flow signal from said pulsatile blood flow detection module, fetches fingerprint and pulsatile blood flow characteristic data from said fingerprint signal and said fingertip pulsatile blood flow signal, matches said fingerprint and pulsatile blood flow characteristic data with predetermined fingerprint and pulsatile blood flow reference data, and then outputs a signal of “
CORRECT”
for allowing the user to carry out the subsequent use after the matching succeeded.

Abstract
A biometric identification apparatus includes a control module, a fingerprint identification module including a fingerprint scan controller and a fingerprint receiver, a pulsatile blood flow detection module including one or multiple light sources and a photo detector, and a holder body defining a fingerprint identification zone and a pulsatile blood flow identification zone. In application, the user simply needs to press the fingertip of one single finger on the fingerprint identification zone and pulsatile blood flow identification zone of the holder body so that the biometric identification apparatus can detect user'"'"'s fingerprint and pulsatile blood flow signals, fetch and convert characteristic data of detected signals, and then match fetched fingerprint and pulsatile blood flow characteristic data with respective reference data for security access control. The application of this dual-biometric identification technology greatly increases the cracking difficulty, achieving better anti-theft function.
