Problems solved by technology

[0003] In practice, it is found that such a situation often occurs in daily life: if the user presses the fingerprint collection area for a long time, it will cause wear and tear on the fingerprint collection area, which will lead to a decrease in the accuracy of the fingerprint sensor and incomplete fingerprint information collected. When the user needs to perform multiple pressing operations to unlock the user terminal, this will reduce the efficiency of legitimate users to unlock the user terminal screen

Abstract

The embodiment of the invention discloses a screen unlocking method and a user terminal. The method comprises the following steps: taking an image of a finger of a current user by a camera so as to obtain a fingerprint; extracting fingerprint characteristic information from the fingerprint image; identifying whether the fingerprint characteristic information is matched with preset fingerprint information stored in advance or not; and if the fingerprint characteristic information is matched with the preset fingerprint information, unlocking a screen. Through implementing the embodiment of the invention, the efficiency of unlocking the screen of the user terminal can be improved.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, in particular to a screen unlocking method and a user terminal. Background technique [0002] Fingerprint identification refers to the realization of fast and accurate identity authentication through fingerprint collection, analysis and comparison of fingerprint features. At present, in order to prevent illegal users from arbitrarily operating a user terminal (such as a smart phone), the user terminal is generally equipped with a fingerprint reader, which is used to lock the user terminal screen with a fingerprint to identify the user's identity. The currently widely used fingerprint readers are mainly push-type fingerprint readers. Usually, designers integrate the push-type fingerprint reader on the home button, or design it on a metal fingerprint ring area on the back of the case. The user only needs to gently place the finger on the home button or the metal fingerprint r...
