1. A method for fingerprint recognition and authentication, comprising: sequentially acquiring a plurality of slice images including a fingerprint pattern via a fingerprint sensor; dividing the slice images into block images; 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 forming a fingerprint pattern template by matching the block images, from which the information of the high-frequency component has been eliminated.
