Abstract

Embodiments of the disclosure provide a method and an apparatus for capturing a screen on a mobile device, the method including: receiving, at the mobile device, a screen-capturing request for a current interface, where the current interface includes first data, and the first data includes personal information; and generating, according to screen-capturing request, a screen capture image for the current interface, where the first data in the current interface is replaced in the screen capture image with second data which is predefined. These embodiments avoid the need to manually mask an image by starting a dedicated image editing tool to anonymize a screen capture image, thereby significantly lowering the relatively high technical threshold of anonymization processing, reducing the error rate, and improving the modification quality of anonymization. Moreover, the replacement is directly made to the image while the screen is captured without interfering with normal use of reading.

First claim

What is claimed is:

1. A method for screen capturing in a mobile device, comprising:
receiving, at the mobile device, a screen-capturing request for a current interface, wherein the current interface comprises first data associated with personal information;
determining whether the mobile device is set in a normal screen capture mode or secure screen capture mode; and
upon determining that the mobile device is set in the secure screen capture mode:
determining a view group on a top layer of the current interface;
searching the view group for views containing the first data;
upon determining that view data corresponding to a first view includes the first data associated with the personal information, remeasuring and redrawing the first view in the current interface to generate a replacement interface of the current interface by replacing the first data with a second predefined data in the current interface;
generating, according to the screen-capturing request, a screen capture image for the replacement interface; and
replacing the second predefined data in the replacement interface with the first data after the screen capture image is generated.

2. The method according to claim 1 , wherein the personal information comprises information associated with a username.

3. The method according to claim 1 , wherein the personal information comprises information associated with a user's head shot.

4. The method according to claim 1 , wherein the personal information comprises information associated with a username and a user's head shot.

5. The method according to claim 1 , wherein the second predefined data comprises mosaic image data.

6. The method according to claim 1 , further comprising remeasuring and redrawing other views of the view group while remeasuring and redrawing the first view.

7. The method according to claim 1 , wherein the normal screen capture mode or the secure screen capture mode is set by a setting switch of the mobile device.

8. The method of claim 1 , wherein the current interface comprises an instant messaging interface.

9. A mobile device, comprising a processor and a memory for storing instructions, wherein the processor, when executing the instructions, is configured to cause the mobile device to:
receive a screen-capturing request for a current interface of the mobile device, wherein the current interface comprises first data associated with personal information;
determine whether the mobile device is set in a normal screen capture mode or secure screen capture mode; and
upon determine that the mobile device is set in the secure screen capture mode:
determine a view group on a top layer of the current interface;
search the view group for views containing the first data;
upon determine that view data corresponding to a first view includes the first data associated with the personal information, remeasure and redraw the first view in the current interface to generate a replacement interface of the current interface by replacing the first data with a second predefined data in the current interface;
generate, according to the screen-capturing request, a screen capture image for the replacement interface; and
replacing the second predefined data in the replacement interface with the first data after the screen capture image is generated.

10. The mobile device according to claim 9 , wherein the personal information comprises information associated with a username.

11. The mobile device according to claim 9 , wherein the personal information comprises information associated with a user's head shot.

12. The mobile device according to claim 9 , wherein the personal information comprises information associated with a username and a user's head shot.

13. The mobile device according to claim 9 , wherein the second predefined data comprises mosaic image data.

14. The mobile device according to claim 9 , wherein the processor, when executing the instructions, is further configured to cause the mobile device to: remeasure and redraw other views of the view group while remeasuring and redrawing the first view.

15. The mobile device according to claim 9 , wherein the normal screen capture mode or the secure screen capture mode is set by a setting switch of the mobile device.

16. The mobile device according to claim 9 , wherein the current interface comprises an instant messaging interface.

17. A non-transitory computer-readable medium, storing an instruction set that, when being executed, causes a machine to perform a method for capturing a screen on a mobile device, wherein the method comprises:
receiving, at the mobile device, a screen-capturing request for a current interface, wherein the current interface comprises first data associated with personal information;
determining whether the mobile device is set in a normal screen capture mode or secure screen capture mode; and
upon determining that the mobile device is set in the secure screen capture mode:
determining a view group on a top layer of the current interface;
searching the view group for views containing the first data;
upon determining that view data corresponding to a first view includes the first data associated with the personal information, remeasuring and redrawing the first view in the current interface to generate a replacement interface of the current interface by replacing the first data with a second predefined data in the current interface;
generating, according to the screen-capturing request, a screen capture image for the replacement interface; and
replacing the second predefined data in the replacement interface with the first data after the screen capture image is generate.

18. The non-transitory computer-readable medium according to claim 17 , wherein the current interface comprises an instant messaging interface.

19. The non-transitory computer-readable medium according to claim 17 , wherein the personal information comprises information associated with a username and a user's head shot.

20. The non-transitory computer-readable medium according to claim 17 , wherein the second predefined data comprises mosaic image data.
