METHOD FOR SCANNING USER BIOMETRIC INFORMATION ON BASIS OF FINGERPRINT CORE POINT AND BIOMETRIC INFORMATION RECOGNITION DEVICE THEREFOR

摘要

The present invention relates to a biometric information recognition device and a method for scanning, by the device, biometric information of a user by selectively activating a plurality of piezoelectric elements. Specifically, the present invention relates to a method for efficiently scanning biometric information of a user by recognizing the core point of a fingerprint of the user to find a location of the core point and then selectively activating only a few piezoelectric elements corresponding to the location; and a device therefor.
