Abstract
According to one embodiment of the present invention, provided is a method for fingerprint recognition and authentication, comprising: a step for sequentially acquiring a plurality of slice images including a fingerprint pattern via a fingerprint sensor; a slice dividing unit for dividing the slice images into block images; a step for converting spatial domain information of the block images into frequency domain information, and eliminating information of a high-frequency component by using a low-pass filter; and a step for forming a fingerprint pattern template by matching the block images, from which the information of the high-frequency component has been eliminated.
