Abstract

Disclosed in the invention is a fingerprint verification method. The method comprises: fingerprints of designated areas of at least two fingers are collected to obtain original fingerprint images of the two fingers; the collected original fingerprint images are combined to obtain a verified fingerprint image; fingerprint feature information of the verified fingerprint image is extracted; and whether the extracted fingerprint feature information matches pre-stored fingerprint feature information is determined and a determination result is outputted. Correspondingly, the invention also discloses a fingerprint verification apparatus. With the method and apparatus, leakage of complete fingerprint information can be prevented from the source of fingerprint collection, thereby improving fingerprint security.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a fingerprint verification method and device. Background technique [0002] Fingerprints refer to the uneven lines on the skin of the front end of a person, and the lines are arranged regularly to form different patterns. Because everyone's fingerprints are different, even between the ten fingers of the same person, there are obvious differences in fingerprints, so fingerprints can be used for identification. The fingerprint feature points provide the confirmation information of the uniqueness of the fingerprint. Among them, the most typical fingerprint feature points are terminal points and bifurcation points, and others include bifurcation points, isolated points, loop points, and short lines. Fingerprint feature point parameters include direction (the node can face a certain direction), curvature (the speed at which the texture direction changes), and position (the posit...
