Abstract

The invention provides a fingerprint recognition method and a mobile terminal. The method comprises the steps that if first touch operation on a first fingerprint recognition area is detected, a first fingerprint image is collected through the first fingerprint recognition area; if second touch operation on a second fingerprint recognition area is detected, a second fingerprint image is collected through the second fingerprint recognition area; and if the time interval between the first touch operation and the second touch operation is smaller than or equal to a preset time interval, at least one of the first fingerprint image and the second fingerprint image is selected to be matched with a fingerprint image stored in the mobile terminal. Therefore, the probability of false trigger of fingerprint recognition can be effectively lowered.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a fingerprint identification method and a mobile terminal. Background technique [0002] With the rapid development of science and technology, the functions of mobile terminals are becoming more and more abundant, and the issue of privacy has become an issue that people are more and more concerned about. In order to better improve security and protect privacy, fingerprint identification is more and more widely used in mobile terminals. [0003] Existing fingerprint recognition includes scratch-type fingerprint recognition, push-type fingerprint recognition and touch-screen fingerprint recognition. Among them, the touch-screen fingerprint recognition integrates the fingerprint recognition function into the touch screen of the mobile terminal, so that the touch screen can support Fingerprint recognition. In the existing fingerprint identification method, when the finger to...
