METHOD OF DETECTING FINGER PRINT WITH FINGER APPARATUS USING OPTICAL TECHNOLOGY AND OPTICAL COHERENCE TOMOGRAPHY TECHNOLOGY

摘要

The present invention provides a method for detecting a fingerprint with a fingerprint device using an optical technology and an optical coherence tomography technique, comprising the steps of: confirming whether a forged fingerprint is performed using an optical coherence tomography technique (step S100); In the step S100, if it is determined that the fingerprint is forged as a result of checking whether the fingerprint is forged, terminating the fingerprint detection (S200); Simultaneously with the step S100, detecting a first fingerprint using an optical technique (step S300); And in step S100, if it is determined that the fingerprint is not a forged fingerprint but an actual human fingerprint, the first fingerprint detected in step S300 is compared with the second fingerprint of the previously stored database, and the matching fingerprint is identified as an individual. Including, identifying or authenticating (S400); in the step S100, only a specific point of the finger contact surface is performed by optical coherence tomography technology, and in the step S300, the entire surface of the finger contact surface is performed by optical technology However, the step S100 and the step S300 proceed at the same time, discloses a fingerprint detection method.
