Problems solved by technology

In the prior art, when performing fingerprint authentication, the mobile terminal needs to compare the fingerprint data input by the user with multiple stored fingerprint templates one by one, and when the fingerprint data input by the user is compared with one of the multiple fingerprint templates, it is used to unlock Only when the fingerprint templates of different fingerprints are the same can be unlocked, the matching process takes a long time and the unlocking efficiency is low

Abstract

The invention provides an unlocking method. The method comprises the following steps: receiving fingerprint data, wherein the fingerprint data comprises image features of the fingerprint; determining a fingerprint template group containing the image features of the fingerprint data; matching the fingerprint data with the fingerprint template data contained in the fingerprint template group; if the matching of the fingerprint data and the fingerprint template data is successful, unlocking. The embodiment of the invention further discloses a mobile terminal. Through the adoption of the method provided by the invention, the fingerprint template group can be fast determined, and the unlocking speed of the mobile terminal is accelerated.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, in particular to an unlocking method and device. Background technique [0002] Nowadays, fingerprint recognition technology has become a standard function of mobile terminals, bringing users a variety of experiences. Fingerprint recognition can not only be used for unlocking and waking up functions of mobile terminals, but also plays an indelible role in the security performance of mobile terminals. The process of fingerprint recognition is basically extracting fingerprint features, saving data and comparing data. The fingerprint data is read by the fingerprint reading device, the original image is preliminarily processed after the fingerprint data is read, and the processed original image is matched with the fingerprint template image. After the matching is successful, the system will be unlocked accordingly. [0003] In the prior art, for different application scenarios...
