Abstract

The invention discloses a mobile terminal unlocking apparatus and method. The apparatus comprises a first acquisition module, an image comparison module, a second acquisition module and a comparison unlocking module, wherein the first acquisition module is used for acquiring a fingerprint image acquired by a sliding type fingerprint identifier of a mobile terminal when the mobile terminal enters an unlocking mode; the image comparison module is used for comparing the fingerprint image with a preset unlocking fingerprint image; the second acquisition module is used for acquiring a sliding parameter acquired by a pressure sensor arranged at the bottom of the sliding type fingerprint identifier when the degree of matching between the fingerprint image and the unlocking fingerprint image is smaller than a first fingerprint threshold; and the comparison unlocking module is used for comparing the sliding parameter with a preset unlocking sliding parameter and unlocking a locking state of the mobile terminal when the degree of matching between the sliding parameter and the unlocking sliding parameter is greater than a first sliding threshold. According to the mobile terminal unlocking apparatus and method, the success rate of fingerprint identification unlocking is increased, a user can input a fingerprint without the need for sliding for multiple times, and the unlocking efficiency of the mobile terminal is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminal unlocking, in particular to a mobile terminal unlocking method and a mobile terminal. Background technique [0002] With the development of mobile terminal unlocking technology, pressure sensors and fingerprint unlocking are more and more widely used in mobile terminals, and the protection of personal privacy has also attracted more and more attention from mobile terminal manufacturers and consumers. At present, the fingerprint unlocking method that is widely used is based on the fingerprint unlocking method of the sliding fingerprint reader. When the finger slides on the surface of the sliding recognition device, the recognition device continuously captures the fingerprints of different areas of the finger to form a "snapshot", and then These "snapshots" are synthesized together to form a fingerprint image that is as large or even larger than the image taken by the tactile sensor ...
