FINGERPRINT AUTHENTICATION SYSTEM AND METHOD OF AUTHENTICATION USING THE SAME

摘要

Provided is a fingerprint authentication system and a method of authentication. The fingerprint authentication system may have a configuration to analyze a reflection wave signal reflected at a surface of an object under examination or an internal of the object under examination by applying a wave signal from at least one of signal communication unit of a fingerprint sensor to the object under examination. In the method of authentication, the controller in the fingerprint authentication system may be configured to selectively perform a first step authentication to authenticate a shape of a fingerprint, and a second step authentication to detect internal biometric information of the object under examination.

1. A fingerprint authentication system comprising:
a fingerprint sensor configured to apply wave signals to an object under examination, and to receive wave signals reflected from the object under examination; a controller configured to control an operation of the fingerprint sensor, and to analyze reflection wave signals of the object under examination received from the fingerprint sensor; and a memory device configured to store information of the object under examination.
