Mobile terminal unlocking method and device

Abstract

The invention provides a mobile terminal unlocking method and device, wherein the method comprises the following steps: when an unlocking request is received, calling an image collector of a mobile terminal; using the image collector to collect a plurality of expression images of a human face in a visual range; extracting expression images containing continuous expression actions from the plurality of collected expression images of the human face in the visual range; analyzing out the continuous expression actions included in the expression images according to the extracted expression images containing the continuous expression actions; matching the analyzed continuous expression actions and preset human face continuous expression actions used for judging whether to unlock or not; determining whether to respond to the unlocking request or not according to the matching result. According to the unlocking mode provided by the invention, a plurality of continuous human face expression actions are used for executing the unlocking, and the mode is a dynamic unlocking mode. Compared with a static unlocking mode in the prior art, the unlocking security can be improved.

Description

technical field [0001] The present invention relates to the field of information security, in particular to an unlocking method and device for a mobile terminal. Background technique [0002] With the rapid development of science and technology, various mobile devices (such as smart phones, notebook computers, etc.) have emerged at the historic moment, and the functions of mobile devices are becoming more and more powerful, which brings great convenience to our study and work. The more functions various mobile devices implement, correspondingly, the more content needs to be protected in the mobile device, especially some information related to privacy or money, etc., should be kept confidential, so as to ensure that users can use it safely and securely Mobile devices. [0003] In practical applications, the user can protect the user's information security by locking the screen of the mobile terminal, and can set multiple ways to unlock, such as sliding, entering a digital p...

AI Technical Summary

Problems solved by technology

Although, unlocking can be achieved by adopting these unlocking methods, there are still problems in different aspects.

Sliding to unlock is convenient and quick to implement, but the security is low. Anyone can easily unlock by sliding the screen; inputting a digital password to unlock is a traditional unlocking method, which requires mobile terminal users to memorize boring numbers and passwords. It is easy to be forgotten, which affects the smooth progress of unlocking; input fingerprint unlocking is a relatively new unlocking method, which uses static fingerprint recognition to perform unlocking operations, but when the user is asleep, its fingerprints are easily Being used by others, the safety and reliability are low
