Example 1

In this embodiment, a smart phone visitor control method is provided, which can collect user face information in real time, monitor whether the current user is the owner and whether the other person peeks when using the mobile phone, and open/close the visitor according to the detection result. Control functions, and will not be easily noticeable to people outside the owner.

In this embodiment, the mobile phone has two states: an unrestricted state and a restricted state, where:

When the mobile phone's visitor control function is disabled, the mobile phone has only one state: an unrestricted state;

When the mobile phone's guest control function is enabled, the mobile phone can switch between an unrestricted state and a restricted state.

In this embodiment, when the mobile phone is in an unrestricted state, the user's operation on the mobile phone is not limited; when the mobile phone is in a restricted state, the user's operation on the mobile phone is limited.

In this embodiment, the collected user facial image is combined with the stored main facial image. Comparative analysis, the results of the analysis have three cases:

1) The current user is the owner himself;

2) The current user is the owner himself, but there are others on the side;

3) The current user is not the owner himself or no user is currently using the phone.

Correspondingly, different access control operations based on the analyzed results include:

When in case 1), the mobile phone state is set to an unrestricted state;

When in case 2), the mobile phone state is set to a restricted state;

When in case 3), the phone status is set to a restricted state.

FIG. 6 is a schematic flowchart of a method for controlling a visitor of a smart phone according to Embodiment 1 of the present invention. As shown in FIG. 6, the method includes:

Step 600: Determine whether the mobile phone guest control function is enabled.

Step 601: When it is determined that the mobile phone guest control mode has been enabled, data collection is started.

Step 602: The camera continuously collects the facial image of the user according to a certain frequency.

Step 603: Store the image of the user's face collected by the camera.

Step 604: The chip with the face recognition analysis capability acquires the collected user facial image, the stored main body facial image, and compares the two to analyze whether the current user is the owner himself or not.

Step 605: If the current user is analyzed as the owner himself, the mobile phone CPU sets the mobile phone state to an unrestricted state.

Step 606: At this time, the operation of the mobile phone by the user is not limited.

Step 607: If it is analyzed that the current user is the owner himself, but the other person is on the side, the mobile phone CPU sets the mobile phone state to the restricted state.

In this embodiment, when the mobile phone changes from the unrestricted state to the restricted state, a prompt appears in the status bar to notify the owner that the current access is restricted. This prompt can't be clearly recognized by people. It only needs to be understood by the owner himself. This prompt has been there until the phone It disappears when it changes from a restricted state to an unrestricted state.

Step 608: The user's operation on the mobile phone is limited at this time.

Step 609: If it is analyzed that the current user is not the owner or the user is not currently using the mobile phone, the mobile phone CPU sets the mobile phone state to a restricted state.

Step 610: The user's operation on the mobile phone is limited at this time.

It should be noted that the information such as the machine face image, the guest control function password, the enable guest control function information, the current mobile phone state, and the like, which may be involved in the embodiment of the present invention, are stored in a medium such as a memory.

The embodiment of the invention overcomes the shortcomings of the guest mode scheme on the existing smart phone, and adopts the face recognition technology to distinguish different users to realize the access control of the mobile phone access, which is more secure and reliable than the previous password control method; The automatic switching between the limited access state and the normal access state avoids the embarrassment brought to the party when the guest mode is turned on.

Each of the above modules may be implemented by a central processing unit (CPU), a digital signal processor (DSP), or a field-programmable gate array (FPGA) in the electronic device.
