Background technique

With the development and advancement of science and technology, intelligent terminals are also rapidly developing and innovating. At present, smart terminals gradually infiltrate into all aspects of people's lives due to their versatility and portability. In particular, the development of the touch screen mode of the smart terminal frees the dependence of the smart terminal on the keyboard, so that the display range of the smart terminal is larger, and the user relies on both hands to touch an icon such as an application program or other shortcut keys on the display interface of the smart terminal. It is possible to start or close the corresponding application, giving the user more freedom to operate the smart terminal.

At present, smart terminals such as mobile phones and tablet computers use capacitive touch screens. Unlike resistive screens, capacitive touch screens can activate the capacitive sensing and identification system at the bottom of the screen for the finest contact from the surface of a charged finger. Trigger any application in the smart terminal. Therefore, the existing smart terminal is provided with a lock screen function to prevent the user from accidentally touching the application program that starts the smart terminal, and brings unnecessary interference to the user. On the other hand, as the user's dependence on the smart terminal increases, the lock screen function on the other hand also protects the user's privacy.

Specifically, the user may start the application management of the smart terminal by touching the form of the shortcut of the smart terminal desktop or the shortcut menu under the operation authority of the smart terminal, and if, for example, the application is selected Sending, by the program icon, or inputting the name of the application, a mobile instruction to the smart terminal, the mode switching module of the smart terminal sensing and identifying the operation of the smart terminal by the user, and selecting the user accordingly The set application is set to a state in which the visitor is invisible, so that when the password is unlocked and the access right is entered, the application is hidden, and the visitor cannot see the application, thereby protecting the user. The privacy program is not peeped or enabled.

In addition, preferably, in this embodiment, the user can switch between the operation authority and the access authority, in particular, from the access authority, by inputting the correct password, the operation authority can be converted, thereby preventing the user from being injured due to a face or the like. When the face appearance is severely changed, when the smart terminal cannot be unlocked by the face recognition technology, the operation authority of the smart terminal can also be activated by means of password unlocking. Referring to FIG. 2, in particular, a user may first trigger the smart terminal to send an operation instruction to the smart terminal, and the face recognition of the smart terminal The module scans and determines that no face exists, and sends a second instruction to the unlocking module of the smart terminal. After receiving the second instruction, the password control module of the smart terminal performs an operation of starting the password unlocking mode. Further, the smart terminal displays an interface such as a password input box or a sliding password interface on the display interface; the user inputs password information consistent with the preset password in the password input box, or slides a consistent password pattern to activate the access right of the smart terminal. To ensure that the user's privacy is not peeped. However, if the user initiates the access right and wants to switch to the operation right, the mode switching instruction may be sent to the smart terminal by the shortcut key of the switching mode under the setting procedure of the access right, the startup mode. Switching the module, so that the mode switching module of the smart terminal can sense and recognize the user's operation action on the smart terminal, thereby starting the password entry mode, jumping out of a password input box in the display interface of the smart terminal or The sliding password interface or another password input interface, so that the user can input a password that is consistent with the preset switching password or a password pattern that is consistent with the preset switching password pattern in the password input box. The smart terminal is switched from access right to operation authority. Correspondingly, in this embodiment, the user can also activate the mode switching module in the operation mode, and input the corresponding switching password to realize the function of switching from the operation authority to the access authority.

In addition, referring to FIG. 3, more preferably, in this embodiment, in order to further improve the accuracy of the face recognition, the smart terminal in this embodiment further includes a blink recognition module, the blink recognition module and the face The module communication connection is determined. In this embodiment, after the face recognition module determines that the face information is consistent with the pre-stored face information, the face recognition module sends a fifth instruction to the blink module receiving station. The fifth command is used to identify whether there is a blinking action. If the blinking action is recognized, the smart terminal is unlocked, and if the blinking action is not recognized, the password unlocking mode is activated. Specifically, when the user initiates the face recognition unlocking process, the user also needs to align the camera with the camera of the smart terminal, so that the face recognition module of the smart terminal captures the face information and determines the person with the pre-existing After the face information is consistent, a fifth command is sent to the blink recognition module, so that the blink recognition module of the smart terminal further scans and determines whether there is a blink action in the face image, if the blink recognition The module recognizes that there is a blinking action in the face screen, and may send an instruction to the unlocking module of the smart terminal to start an operation mode of the smart terminal; otherwise, the blink recognition module sends an instruction to the unlocking module. , activate password unlock mode. Based on the above settings, it can be further ensured that the user is unlocked the smart terminal, and if other users use the image of the user to unlock the smart terminal, the operation mode of the smart terminal cannot be activated, and the privacy of the user is further protected. peep.
