Abstract

The invention discloses a fingerprint identification device, which includes: an acquisition module, used to acquire each fingerprint corresponding to the touch operation in the fingerprint identification area when a touch operation input based on the fingerprint identification area is detected. Sub-areas; a first calculation module, configured to calculate the relative distance between each of the sub-areas and the central sub-area of ​​the fingerprint identification area based on the position information of each of the sub-areas and the position information of the central sub-area of ​​the fingerprint identification area The second calculation module is used to calculate the touch area of ​​the touch operation in the fingerprint recognition area according to the calculated relative distance; the acquisition module is used to reach the preset area when the calculated touch area , collect fingerprint information corresponding to the touch operation for fingerprint identification. The invention also discloses a fingerprint identification method. The invention improves the prevention of false report of fingerprints and improves the accuracy of fingerprint identification.

Description

technical field [0001] The invention relates to the technical field of fingerprints, in particular to a fingerprint identification device and method. Background technique [0002] With the development and maturity of fingerprint technology, more and more terminals are equipped with fingerprint devices for fingerprint identification. The fingerprint device is the fingerprint identification area. The current fingerprint identification is basically determined by the response sensitivity of the fingerprint device. , when the response sensitivity in the fingerprint device is too high, if you accidentally input a touch operation in the edge area of ​​the fingerprint device, that is, touch the fingerprint device by mistake, fingerprint recognition will also be performed. Therefore, this fingerprint recognition method is easy False reporting of fingerprints by fingerprint devices occurs, resulting in inaccurate fingerprint recognition. Contents of the invention [0003] The main ...
