Abstract

Embodiments of the invention disclose a fingerprint unlocking method and a mobile terminal. The fingerprint unlocking method can comprise the steps of obtaining a fingerprint image input by a user; determining a target fingerprint group corresponding to the fingerprint image, wherein the target fingerprint group comprises a plurality of fingerprint templates; performing matching on the fingerprint templates and the fingerprint image in sequence according to a preset sequence; and when any fingerprint template in the fingerprint templates is successfully matched with the fingerprint image, unlocking the mobile terminal. With the adoption of the embodiments of the method and the mobile terminal, the target fingerprint group is firstly determined before fingerprint matching, so that the matching range can be reduced; and the matching is performed according to the preset sequence, so that the fingerprint matching frequency can be further reduced, the matching speed can be increased, and the fingerprint identification efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of intelligent terminals, in particular to a fingerprint unlocking method and a mobile terminal. Background technique [0002] With the development of fingerprint identification technology, the application of fingerprint information is becoming more and more extensive. Nowadays, many mobile terminals on the market are equipped with fingerprint identification modules, which can apply fingerprint identification technology to mobile terminals to improve the security of mobile terminals. [0003] Generally, for different application scenarios, the user may set fingerprints of different fingers as templates in different scenarios. Even for the same finger, since the fingerprint images obtained under different input situations are not the same, there may be multiple fingerprint templates corresponding to the same finger, so many fingerprint templates are usually stored in the mobile terminal. In the prior art, wh...
