Mobile terminal based control method and system preventing fingerprint sensor false triggering

Abstract

The invention discloses a mobile terminal based control method and system preventing fingerprint sensor false triggering; the method comprises the following steps: A, presetting a valid fingerprint sensor triggering mobile terminal usage direction; B, using a mobile terminal central processor to detect the mobile terminal usage direction, if the usage direction is same with the preset valid fingerprint sensor triggering usage direction, enabling the fingerprint sensor, otherwise, forbidding the fingerprint sensor. The method and system can prevent fingerprint sensor false triggering in daily usage of the mobile terminal, so fingerprint detection cannot be frequently carried out, thus ensuring the battery to be used in long term, prolonging the battery service life, improving safety, and providing conveniences for users.

Description

technical field [0001] The present invention relates to the field of mobile terminals, in particular to a control method and system for preventing false triggering of a fingerprint sensor based on a mobile terminal. Background technique [0002] With the rapid development of mobile terminal technology, more and more mobile terminals have added fingerprint sensors for operations such as unlocking the mobile terminal and mobile payment for the sake of safety and convenience. Fingerprint sensors are all set on the surface of the mobile terminal, and fingerprints are collected by touching the fingerprint sensor exposed on the surface of the mobile terminal; just because the fingerprint sensor is set on the surface of the mobile terminal, it is easy to cause mistakes when using and carrying the mobile terminal in daily life. Trigger, and once the fingerprint sensor is triggered, the fingerprint sensor will think that the fingerprint input by the user has been collected and compar...

Problems solved by technology

Fingerprint sensors are all set on the surface of the mobile terminal, and fingerprints are collected by touching the fingerprint sensor exposed on the surface of the mobile terminal; just because the fingerprint sensor is set on the surface of the mobile terminal, it is easy to cause mistakes when using and carrying the mobile terminal in daily life. Trigger, and once the fingerprint sensor is triggered, the fingerprint sensor will think that the fingerprint input by the user has been collected and compared with the fingerprint entered in advance. Due to the complexity of the fingerprint detection algorithm, the comparison process will often make the central processing unit of the mobile terminal calculate at full speed; If the user frequently triggers the fingerprint sensor by mistake in daily use, the battery power will be drained immediately.

[0003] That is to say, in the mobile terminal in the prior art, it is easier for the user to accidentally trigger the fingerprint sensor when using the mobile terminal on a daily basis (for example, if the user puts the mobile terminal in the pocket in summer, it is easy to trigger the fingerprint sensor by mistake if it is facing the direction of the human skin). In the process of use, it is easy to trigger the fingerprint sensor by mistake frequently, and the battery power will be exhausted immediately, wasting power and causing inconvenience to users.
