Abstract

A method for a device to hide privacy information is provided. The method includes: recognizing a piece of privacy information in an image; identifying an information category corresponding to the piece of privacy information; and performing hiding processing to the piece of privacy information in the image based on the information category.

Claims

1. A method for a device to hide privacy information, comprising:

recognizing a piece of privacy information in an image;

identifying an information category corresponding to the piece of privacy information; and

performing hiding processing to the piece of privacy information in the image based on the information category.

2. The method according to claim 1, wherein the information category is identified based on a preset rule if the piece of privacy information is text information.

3. The method according to claim 1, wherein the information category is identified based on a preset face information database if the piece of privacy information is face information.

4. The method according to claim 1, further comprising:

if the image is a screen capture, acquiring at least one of application program information or display interface information corresponding to the screen capture; and

identifying the information category corresponding to the piece of privacy information in the image based on the at least one of application program information or display interface information.

5. The method according to claim 1, further comprising:

detecting whether the information category is a predetermined category to be hidden; and

hiding the piece of privacy information if it is detected that the information category is a predetermined category to be hidden.

6. The method according to claim 5, further comprising:

determining at least one of a hiding range or a hiding means corresponding to the piece of privacy information based on the information category; and

hiding the piece of privacy information based on the at least one of the hiding range or the hiding means.

7. The method according to claim 1, further comprising:

if the image is a screen capture, acquiring at least one of application program information or display interface information corresponding to the screen capture;

identifying an image region which contains the piece of privacy information based on the at least one of application program information or display interface information; and

recognizing the piece of privacy information based on the image region.

8. A device for hiding privacy information, comprising:

a processor; and

a memory for storing instructions executable by the processor;

wherein the processor is configured to;

recognize a piece of privacy information in an image;

identify an information category corresponding to the piece of privacy information; and

perform hiding processing to the piece of privacy information in the image based on the information category.

9. The device according to claim 8, wherein the processor is further configured to:

identify the information category based on a preset rule if the piece of privacy information is text information.

10. The device according to claim 8, wherein the processor is further configured to:

identify the information category based on a preset face information database if the piece of privacy information is face information.

11. The device according to claim 8, wherein the processor is further configured to:

if the image is a screen capture, acquire at least one of application program information or display interface information corresponding to the screen capture; and

identify the information category based on the at least one of application program information or display interface information.

12. The device according to claim 8, wherein the processor is further configured to:

detect whether the information category is a predetermined category to be hidden; and

hide the privacy information if it is detected that the information category is a predetermined category to be hidden.

13. The device according to claim 12, wherein the processor is further configured to:

determine at least one of a hiding range or a hiding means corresponding to the piece of privacy information based on the information category; and

hide the piece of privacy information based on the at least one of the hiding range or the hiding means.

14. The device according to claim 8, wherein the processor is further configured to:

if the image is a screen capture, acquire at least one of application program information or display interface information corresponding to the screen capture;

identify an image region which contains the piece of privacy information based on the at least one of application program information or display interface information; and

recognize the piece of privacy information based on the image region.

15. A non-transitory computer-readable medium having stored therein instructions that, when executed by a processor of a terminal device, cause the terminal device to perform operations including:

recognizing a piece of privacy information in an image;

identifying an information category corresponding to the piece of privacy information; and

performing hiding processing to the piece of privacy information in the image based on the information category.
