Embodiment 1

[0044] figure 1 It is a schematic diagram of an unlocking process provided by an embodiment of the present invention, and the process includes the following steps:

[0045] S101: Collect first image information if an optical signal is received.

[0046] An unlocking method provided by an embodiment of the present invention is applied to a mobile terminal, specifically to a mobile terminal with a front camera. The mobile terminal has photosensitive components. When the photosensitive components of the mobile terminal sense light signals, they will send an electrical signal to the main control chip of the mobile terminal, and the mobile terminal will start the camera application to collect and push information. Specifically, it may be that the photosensitive element senses a light signal, that is, sends an electrical signal to the main control chip. In order to save the power of the mobile terminal and prolong the standby time of the mobile terminal, it may also be that the lig...

Embodiment 2

[0056] If the extracted first face feature information is not successfully matched with the face feature information stored in the database, it is considered that the user currently holding the mobile terminal is an illegal user. In order to ensure the security of the mobile terminal, the mobile terminal will do out response. On the basis of the above embodiments, in the embodiment of the present invention, if the matching is unsuccessful, the method further includes:

[0057] Control the mobile terminal to take pictures and output alarm information.

[0058] In the embodiment of the present invention, if the face recognition module matches the extracted first face feature information with the face feature information stored in the database, if the matching is unsuccessful, then the person currently holding the mobile terminal is considered The user is an invalid user. The face recognition module notifies the main control chip that the matching of face feature information is...

Embodiment 3

[0081] The mobile terminal extracts the first facial feature information from the collected first image information, and matches the first facial feature information with the facial feature information stored in the database. The user is an illegal user, and it may also be that the current position between the legal user and the mobile terminal is inappropriate, or there is a problem with the clarity of the image, etc., resulting in the extracted face image information not accurately reflecting the face image information. The facial features of the user, so in order to improve the accuracy of unlocking control, on the basis of the above-mentioned embodiment 2, in the embodiment of the present invention, before the control mobile terminal takes pictures and outputs the warning information, the method also includes:

[0082] Update the current number of unsuccessful matches;

[0083] If the number of times reaches the preset number of times threshold, follow-up steps are perform...

Abstract

The embodiment of the invention discloses an unlocking method and device, which are used for solving the problems that the unlocking efficiency of a mobile terminal is low, the use efficiency of other applications in the mobile terminal is low, and user experience is not high. The method comprises the following steps of acquiring image information when receiving an optical signal; and when first face feature information extracted in the image information is successfully matched with face feature information conserved in a database, then controlling the mobile terminal to unlock. Since the mobile terminal in the embodiment of the invention extracts the first face feature information in the acquired image information when receiving the optical signal, and unlocks when the first face feature information is successfully matched with the face feature information conserved in the database, so that the unlocking process does not need users to press an unlock button on a shell of the mobile terminal, and the mobile terminal is directly unlocked to improve the unlocking efficiency; and other applications in the mobile terminal can be directly used after unlocking, so that the use efficiency of the other applications by the users in the mobile terminal is improved, and user experience is also improved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to an unlocking method and device. Background technique [0002] With the continuous advancement of science and technology, people's lives are becoming more and more convenient, the popularity of mobile terminals is getting higher and higher, the configuration of mobile terminals is also getting higher and higher, and the utilization rate of users for mobile terminals is also getting higher and higher. . At present, mobile terminals basically have a screen lock function. When a user does not want others to see the contents of his mobile terminal, or does not use the mobile terminal for a long time, he can set the mobile terminal to a locked state, that is, to lock its screen. Other people who do not know the lock screen password will not be able to view the content in the mobile terminal. When a user wants to use his own mobile terminal, he first needs to perform ...
