Abstract

The invention discloses a fingerprint recognition method and a mobile terminal. The method is applied to a mobile terminal with a touch screen. The method comprises the steps that according to operation of a user on the touch screen, a fingerprint recognition region on the touch screen is determined; fingerprint data is collected in the fingerprint recognition region, and verification is conducted on the collected fingerprint data. According to the fingerprint recognition method and the mobile terminal, based on the operation of the user on the touch screen, the fingerprint recognition region is dynamically adjusted, it is unnecessary for the user to adjust the holding posture, the problem that a finger touching region deviates from the fingerprint recognition region is avoided, and the usability and the success rate of fingerprint recognition are improved.

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] At present, the screen-to-body ratio of smart terminals such as mobile phones and PADs continues to increase, and fingerprint recognition devices are usually set at fixed positions. When users use smart terminals, they often need to adjust their holding posture or stretch their fingers for fingerprint recognition, which is very difficult. It is inconvenient, and it will also cause the problem that the finger touch area deviates from the fingerprint identification area, resulting in low ease of use and low success rate of fingerprint identification. Contents of the invention [0003] In view of this, the present invention provides a fingerprint identification method and a mobile terminal to solve the problems of low usability and success rate of fingerprint identification in the prior...
