Example 1:

As shown in Figure 1, a user authority control method based on face recognition includes the following steps:

S200, the electronic device receives an instruction to control the application program.

The electronic device is a smart phone, a smart watch or a tablet computer; the instruction includes starting, updating or uninstalling an application program; the application program includes a system application program of the electronic device and an installed third-party application program.

S201, judging whether the application program is in the preset restricted application list, if not, proceed to step S205; if yes, proceed to step S202.

The restricted application list is a list of application programs that need to be controlled by user permissions; the preset restricted application list includes at least two applications, SMS and dial-up, and it is judged whether the application program controlled by the command is in the restricted application list, and if so , enter step S202.

The current user needs to send a text message or make a call, or call a text message or dial-up application during the execution of the application program, that is, the terminal receives an instruction to start the text message application or the dial-up application, and then enters step S202.

S202. Acquire the image of the current user.

Specifically, the front camera of the electronic device is turned on, prompting the current user to take a face image or automatically acquiring an image in front of the front camera.

S203. Use face recognition technology to determine whether the image of the current user is consistent with the image of the preset restricted user. If yes, go to step S204; otherwise, go to step S205.

The face recognition technology is an existing technology, and the restricted user refers to a user who does not have control authority for applications in the restricted application list.

Analyze the image of the current user acquired in step S202 to obtain the face in the image, perform feature matching on the face and the image of the preset restricted user, and if the features are consistent, proceed to step S204; otherwise, proceed to step S204; S205.

In particular, if the image does not contain a human face, it is determined that it is inconsistent with the image features of the preset restricted user, then enter step S205; if the image contains multiple faces, as long as one of the faces is consistent with the preset restricted user If the images are consistent, go to step S204.

S204, not executing the instruction.

S205. Execute the instruction.

In this embodiment, face recognition technology is used to control user rights, and the application programs in the preset restricted application list will not execute the instructions of the restricted user; and when people other than the restricted user use the electronic device, able to operate normally.

Taking the restricted user as a child as an example, the parent puts the deduction application in the mobile phone and the application containing important information into the restricted application list. Information or operation of certain fee-deducting applications to avoid economic losses for parents; at the same time, it can also prevent information loss caused by accidental deletion of applications.

Example 2:

As shown in Figure 2, on the basis of Embodiment 1, this embodiment adds the following steps before step S200:

S100, turn on the child mode.

S101, preset an exit password.

Specifically, an exit password for exiting the children's mode is set in advance, and the exit password is an existing technology such as a digital password, a graphic password, a fingerprint, or a human face.

S102. Preset an image of a limited user.

Specifically, the camera of the electronic device is turned on, and the face image of the restricted user is captured and stored.

S103, a preset restricted application list.

The preset restricted application list includes at least two applications, text messaging and dialing. Users can select the application that needs to be managed by child mode among the installed applications of the electronic device, add it to the restricted application list, or delete it. Restrict applications in the application list.

S104, detecting in real time whether to exit the child mode.

Check in real time whether an instruction to exit the child mode is received, if yes, go to step S105; if not, go to step S200.

S105, verify whether the password currently input by the user is consistent with the exit password preset in step S101, if yes, go to step S106; otherwise, return to step S104.

S106, exit the child mode.

In this embodiment, the user can enable or exit the child mode as required, and preset images of restricted users and a list of restricted applications, which improves user experience.
