Abstract

A privacy protection method for the electronic device includes: starting face change detection, where the face change detection is continuously detecting, in a current unlocking period, whether a face in front of a display of the electronic device changes; after starting the face change detection, detecting an operation of starting a first private application; and in response to the operation and determining that a result of the face change detection is that the current face does not change, displaying first private content corresponding to the first private application; or in response to the operation and determining that a result of the face change detection is that the current face changes, displaying first non-private content, where the first non-private content does not include first private content.

First claim

What is claimed is:

1. A privacy protection method for an electronic device, the electronic device having a camera positioned to perform face change detection in a predetermined area in front of the display of the electronic device, the method comprising:
with the camera, starting the face change detection, wherein the face change detection is continuously detecting, in a current unlocking period, whether a face in front of a display of the electronic device changes by performing a plurality of detection attempts at least a predetermined frequency, and the change of the face in front of the display of the electronic device is specifically that the current face in front of the display of the electronic device does not match a reference face; and
after starting the face change detection, and when displaying a first display interface:
in response to receiving a new message from a first private application and a result of the face change detection being that the current face changes, displaying only a part of content of the new message on the first display interface, wherein the first private application contains a browser, a payment software, a chat software, or a social software; and
after displaying only the part of the content of the new message, continuing to acquire a result of the face change detection, and in response to a result of the face change detection being that the current face does not change, displaying all content of the new message on the first display interface.

2. The privacy protection method of claim 1 , wherein the part of the content of the new message does not contain a sender of the message or private content included in the new message.

3. The privacy protection method of claim 1 , wherein the result of the face change detection is that the current face changes contain a quantity of faces changes.

4. The privacy protection method of claim 1 , wherein the result of the face change detection is that the current face switches from an authorized user to an unauthorized user and then switches back to the authorized user.

5. The privacy protection method of claim 1 , further comprising:
in response to a preset operation in the first display interface, displaying all content of the new message.

6. The privacy protection method of claim 1 , wherein the first display interface contains a minus one screen or a home screen.

7. The privacy protection method of claim 1 , wherein receiving the new message from the first private application further comprises:
determining whether the new message is a message of the first private application.

8. The privacy protection method of claim 7 , further comprising:
displaying all content of the new message when the new message is not the message of the first private application.

9. An electronic device, comprising:
one or more processors;
a memory;
a plurality of applications;
a display, and a camera positioned to perform face change detection in a predetermined area in front of the display; and
one or more computer programs, wherein the one or more computer programs are stored in the memory, the one or more computer programs comprise instructions, and when the instructions are executed by the electronic device, the electronic device is enabled to perform the following steps:
with the camera, starting the face change detection, wherein the face change detection is continuously detecting, in a current unlocking period, whether a face in front of the display of the electronic device changes by performing a plurality of detection attempts at least a predetermined frequency, and the change of the face in front of the display of the electronic device is specifically that the current face in front of the display of the electronic device does not match a reference face; and
after starting the face change detection, and when displaying a first display interface:
in response to receiving a new message from a first private application and a result of the face change detection being that the current face changes, displaying only a part of content of the new message on the first display interface, wherein the first private application contains a browser, a payment software, a chat software, or a social software; and
after displaying only the part of the content of the new message, continuing to acquire a result of the face change detection, and in response to a result of the face change detection being that the current face does not change, displaying all content of the new message on the first display interface.

10. The electronic device of claim 9 , wherein the part of the content of the new message does not contain a sender of the message or private content included in the new message.

11. The electronic device of claim 9 , wherein the result of the face change detection is that the current face changes contain a quantity of faces changes.

12. The electronic device of claim 9 , wherein the result of the face change detection is that the current face switches from an authorized user to an unauthorized user and then switches back to the authorized user.

13. The electronic device of claim 9 , wherein the electronic device is further enabled to display all content of the new message in response to a preset operation in the first display interface.

14. The electronic device of claim 9 , wherein the first display interface contains a minus one screen or a home screen.

15. The electronic device of claim 9 , wherein receiving the new message from the first private application further comprises:
determining whether the new message is a message of the first private application.

16. The electronic device of claim 15 , wherein the electronic device is further enabled to perform:
displaying all content of the new message when the new message is not the message of the first private application.

17. The electronic device of claim 9 , wherein the first private application contains a browser, a payment software, a chat software, or a social software.

18. A non-transitory computer-readable storage medium, comprising instructions, wherein when the instructions are run on an electronic device having a camera positioned to perform face change detection in a predetermined area in front of a display of the electronic device, the electronic device is enabled to perform a method comprising:
with the camera, starting face change detection, wherein the face change detection is continuously detecting, in a current unlocking period, whether a face in front of the display of the electronic device changes by performing a plurality of detection attempts at least a predetermined frequency, and the change of the face in front of the display of the electronic device is specifically that the current face in front of the display of the electronic device does not match a reference face; and
after starting the face change detection, and when displaying a first display interface:
in response to receiving a new message from a first private application and a result of the face change detection being that the current face changes, displaying only a part of content of the new message on the first display interface, wherein the first private application contains a browser, a payment software, a chat software, or a social software; and
after displaying only the part of the content of the new message, continuing to acquire a result of the face change detection, and in response to a result of the face change detection being that the current face does not change, displaying all content of the new message on the first display interface.
