Abstract

A privacy protection method and a terminal device are provided. The privacy protection method in a terminal device includes receiving a user input of designated multimedia content that is stored in the terminal device, detecting an activation of a privacy mode on the terminal device, determining a set of private multimedia content stored in the terminal device based on the designated multimedia content, and preventing the set of private multimedia content from being displayed on the terminal device.

First claim

What is claimed is:

1. A privacy protection method in a terminal device, the privacy protection method comprising:
receiving a first user input to designate a multimedia content in the terminal device;
in response to the first user input, identifying, from multimedia contents stored in the terminal device, a set of multimedia contents based on at least one of semantic information, a particular type, a user type, and an environment type, in association with the designated multimedia content;
determining whether the identified set of multimedia contents is to be shown or hidden and displaying on a display of the terminal device, a first group of the identified set of multimedia contents and a second group of remaining multimedia contents other than the identified set of multimedia contents;
receiving a second user input; and
in response to the second user input,
displaying the identified set of multimedia contents determined to be shown.

2. The privacy protection method of claim 1 , wherein the identifying the set of multimedia contents comprises:
obtaining the designated multimedia content; and
identifying the set of multimedia contents having the semantic information that corresponds to the designated multimedia content.

3. The privacy protection method of claim 1 , wherein the identifying the set of multimedia contents comprises identifying the set of multimedia contents conforming to the particular type, and
wherein the particular type comprises at least one of: a designated subject, a subject of multimedia file designated by a user, an object in a designated multimedia file, designated private information, and private information in the designated multimedia file.

4. The privacy protection method of claim 1 , wherein the designated multimedia content is obtained by receiving a user selection.

5. The privacy protection method of claim 1 , wherein the semantic information includes at least one of an object, a plurality of objects, a scene, and an event.

6. The privacy protection method of claim 1 , wherein the identifying the set of multimedia contents comprises:
identifying the user type of a user currently using the terminal device; and
identifying the set of multimedia contents corresponding to the user type.

7. The privacy protection method of claim 1 , wherein the identifying the set of multimedia contents comprises:
identifying the environment type of an environment where the terminal device is currently located; and
identifying the set of multimedia contents satisfying the environment type.

8. The privacy protection method of claim 1 , further comprising at least one of:
preventing use of a designated application;
preventing use of a designated function of the designated application;
preventing access to the identified set of multimedia contents; and
hiding private information in the designated application.

9. The privacy protection method of claim 1 , wherein the designated multimedia content includes at least one of:
a multimedia content of a designated multimedia file;
a content designated from the designated multimedia file;
a multimedia content corresponding to a designated subject;
a multimedia content corresponding to a subject of the designated multimedia file;
a multimedia content including a designated object;
a multimedia content including an object of the designated multimedia file;
a multimedia content including designated private information;
a multimedia content including private information of the designated multimedia file;
a multimedia content corresponding to the user type of a current user of the terminal device; and
a multimedia content corresponding to the environment type of a current environment of the terminal device.

10. The privacy protection method of claim 1 , wherein the first user input and the second user input is received from an external device through a communication interface.

11. The privacy protection method of claim 10 , further comprising adjusting the set of multimedia contents based on a multimedia content set adjustment instruction transmitted by the external device in response to a detection of the multimedia content set adjustment instruction.

12. The privacy protection method of claim 1 , further comprising:
detecting application prompt information to be displayed on the terminal device; and
performing at least one of:
hiding private information included in the application prompt information, and
transmitting the private information included in the application prompt information to another terminal device associated with the terminal device for displaying the private information on the another terminal device.

13. The privacy protection method of claim 12 , wherein the application prompt information includes at least one of incoming call prompt information, text message prompt information, chat message prompt information, email prompt information, schedule prompt information, and memo prompt information.

14. A terminal device comprising:
a display; and
a processor configured to:
receive a first user input to designate a multimedia content in the terminal device;
in response to the first user input, identify, from multimedia contents stored in the terminal device, a set of multimedia contents based on at least one of semantic information; a particular type; a user type; and an environment type, in association with the designated multimedia content,
determine whether the identified set of multimedia contents is to be shown or hidden and display on a display of the terminal device, a first group of the identified set of multimedia contents and a second group of remaining multimedia contents other than the identified set of multimedia contents;
receive a second user input;
in response to the second user input,
display the identified set of multimedia contents determined to be shown.

15. A computer-program product comprising a non-transitive computer-readable storage medium storing instructions which, when executed by a processor, cause the processor to:
receive a first user input to designate a multimedia content in a terminal device;
in response to the first user input, identify, from multimedia contents stored in the terminal device, a set of multimedia contents based on at least one of semantic information, a particular type, a user type, and an environment type, in association with the designated multimedia content;
determine whether the identified set of multimedia contents is to be shown or hidden and displaying on a display of the terminal device, a first group of the identified set of multimedia contents and a second group of remaining multimedia contents other than the identified set of multimedia contents; and
receive a second user input; and
in response to the second user input, display the identified set of multimedia contents determined to be shown.

16. The computer-program product of claim 15 , wherein the identifying the set of multimedia contents comprises:
obtaining the designated multimedia content; and
identifying the set of multimedia contents having the semantic information that corresponds to the designated multimedia content.

17. The computer-program product of claim 15 , wherein a privacy mode is activated by an authorized user of the terminal device through another device associated with the terminal device.
