Abstract

A privacy filter for an electronic display (e.g., of a mobile device) may be dynamically applied based on multiple factors. The application of the privacy filter may include determining that data to be displayed on the electronic display is of a private nature. If so, a location context is then determined based on whether the location of the electronic display is public and therefore someone other than the user of mobile device might view the electronic display. If the location is public, boundaries associated with an area of the electronic display where the private data is to be displayed may be detected so that a privacy filter may generated dynamically based on the data, the location context and the boundaries. The privacy filter is configured to restrict the viewing angle of the entire electronic display or of a sub-area of the electronic display within the determined boundaries.

Claims

1. A system for dynamic application of a privacy filter on an electronic display, the system comprising:

a processor; and

a memory coupled to the processor, the memory including instructions which, when executed by the processor, cause the system to;

determine that data to be displayed on the electronic display is private;

determine a location context for the electronic display;

determine boundaries associated with an area of the electronic display where the private data is to be displayed; and

generate a privacy filter based on the data, the location context and the boundaries, wherein the privacy filter is configured to restrict the viewing angle of the area of the electronic display where the private data is to be displayed.

2. The system of claim 1, wherein the instructions to determine that data to be displayed on the electronic display is private are based on:

a type of the data, tags embedded in the data, an application associated with the data or matching the data to personal data of a user.

3. The system of claim 1, wherein:

the instructions to determine the location context for the electronic display comprise instructions to use a global positioning system (GPS) receiver to determine a location of the electronic display; and

the instructions to generate the privacy filter comprise instructions to determine that the location is a public location.

4. The system of claim 1, wherein:

the instructions to determine the location context for the electronic display comprise instructions to use a calendar application to determine a location of the electronic display; and

the instructions to generate the privacy filter comprise instructions to determine that the location is a public location.

5. The system of claim 1, wherein:

the instructions to determine the location context for the electronic display comprise instructions to use an antenna to detect a computer network associated with a location; and

the instructions to generate the privacy filter comprise instructions to determine that the location is a public location.

6. The system of claim 1, wherein:

the instructions to determine the location context for the electronic display comprise instructions to use a microphone to measure ambient noise at a location; and

the instructions to generate the privacy filter comprise instructions to determine that the location is a public location.

7. The system of claim 1, wherein the instructions to determine the boundaries comprise instructions to detect an area of the electronic display associated with text input by a user via a keyboard.

8. The system of claim 1, wherein the instructions to generate the privacy filter comprise instructions to apply a gray background and a seamless pattern composed of asymmetric curved lines to an area of the electronic display within the determined boundaries.

9. The system of claim 8, wherein the instructions to generate the privacy filter comprise instructions to adjust the opacity or contrast of the electronic display based on the brightness of the electronic display.

10. The system of claim 9, wherein the instructions to generate the privacy filter comprise instructions to receive a user selection of a darkness of the gray background, a density of the seamless pattern and a level of opacity or contrast of the electronic display such that the data is completely obscured to the user at a viewing angle of 45 degrees or more and a viewing distance of 23 inches or more.

11. A method for dynamic application of a privacy filter on an electronic display, said method comprising:

determining that data to be displayed on the electronic display is private;

determining a location context for the electronic display;

determining boundaries associated with an area of the electronic display where the private data is to be displayed; and

generating a privacy filter based on the data, the location context and the boundaries, wherein the privacy filter is configured to restrict the viewing angle of the area of the electronic display where the private data is to be displayed.

12. The method of claim 11, wherein determining that data to be displayed on the electronic display is private is based on:

a type of the data, tags embedded in the data, an application associated with the data or matching the data to personal data of a user.

13. The method of claim 11, wherein:

determining the location context for the electronic display comprises using a global positioning system (GPS) receiver to determine a location of the electronic display; and

generating the privacy filter comprises determining that the location is a public location.

14. The method of claim 11, wherein:

determining the location context for the electronic display comprises using a calendar application to determine a location of the electronic display; and

generating the privacy filter comprises determining that the location is a public location.

15. The method of claim 11, wherein:

determining the location context for the electronic display comprises using an antenna to detect a computer network associated with a location; and

generating the privacy filter comprises determining that the location is a public location.

16. The method of claim 11, wherein:

determining the location context for the electronic display comprises using a microphone to measure ambient noise at a location; and

generating the privacy filter comprises determining that the location is a public location.

17. The method of claim 11, wherein determining the boundaries comprises detecting an area of the electronic display associated with text input by a user via a key board.

18. The method of claim 11, wherein generating the privacy filter comprises applying a gray background and a seamless pattern composed of asymmetric curved lines to an area of the electronic display within the determined boundaries.

19. The method of claim 18, wherein generating the privacy filter comprises adjusting the opacity or contrast of the electronic display based on the brightness of the electronic display.

20. The method of claim 19, wherein generating the privacy filter comprises receiving a user selection of a darkness of the gray background, a density of the seamless pattern and a level of opacity or contrast of the electronic display such that the data is completely obscured to the user at a viewing angle of 45 degrees or more and a viewing distance of 23 inches or more.

21. At least one computer-readable storage medium having instructions stored thereon for dynamic application of a privacy filter on an electronic display, which when executed by a processor of a machine, cause the machine to:

determine that data to be displayed on the electronic display is private;

determine a location context for the electronic display;

determine boundaries associated with an area of the electronic display where the private data is to be displayed; and

generate a privacy filter based on the data, the location context and the boundaries, wherein the privacy filter is configured to restrict the viewing angle of the area of the electronic display where the private data is to be displayed.

22. The computer-readable storage medium of claim 21, wherein the instructions to determine that data to be displayed on the electronic display is private are based on:

a type of the data, tags embedded in the data, an application associated with the data or matching the data to personal data of a user.

23. The computer-readable storage medium of claim 21, wherein:
