Securing image data detected by an electronic device

1. A method of securing an image displayed on an external display device and detected by an electronic device, the method comprising:

generating image data associated with the detected image using the electronic device;

detecting, by the electronic device, a security marker displayed by the external display device, the security marker being periodically displayed to be undetectable by a human eye that is viewing the display device;

in response to detecting the security marker, modifying the image data to obscure an image portion circumscribed by a security boundary defined by the detected security marker; and

generating a captured image including the obscured image portion for securing the detected image.

2. The method of claim 1 , wherein the image displayed on the external display device includes a plurality of image frames, wherein the image frames are displayed by the display device at a first frequency, and wherein the security marker is displayed by the display device at a second frequency, and wherein the first frequency is greater than the second frequency.

3. The method of claim 1 , further comprising:

displaying a message on a viewfinder of the electronic device, the message notifying a user of the electronic device that capturing image data is unauthorized.

4. The method of claim 1 , further comprising:

displaying, based on the security marker, a message on a viewfinder of the electronic device, the message including information associated with the generated image data.

5. An electronic device comprising:

a camera;

a memory device; and

a processor coupled to the camera and the memory device, the processor being configured to:

generate image data associated with an image displayed on an external display device and detected using the camera;

detect, using the camera, a security marker displayed by the external display device, the security marker being periodically displayed to be undetectable by a human eye that is viewing the display device;

in response to detecting the security marker, modify the image data to obscure an image portion circumscribed by a security boundary defined by the detected security marker; and

generate a captured image including the obscured image portion for securing the detected image.

6. The electronic device of claim 5 , wherein the image displayed on the external display device includes a plurality of image frames, wherein the image frames are displayed by the display device at a first frequency, and wherein the security marker is displayed by the display device at a second frequency, and wherein the first frequency is greater than the second frequency.

7. The electronic device of claim 5 , wherein the processor is further configured to:

display a message on a viewfinder of the electronic device, the message notifying a user of the electronic device that capturing image data is unauthorized.

8. A non-transitory computer-readable storage medium comprising processor-executable instructions which, when executed by a processor of an electronic device, causes the electronic device to:

generate image data associated with an image displayed on an external display device and detected using the electronic device;

detect, by the electronic device, a security marker displayed by the external display device, the security marker being periodically displayed to be undetectable by a human eye that is viewing the display device;

in response to detecting the security marker, modify the image data to obscure an image portion circumscribed by a security boundary defined by the detected security marker; and

generate a captured image including the obscured image portion for securing the detected image.

9. The electronic device of claim 5 , wherein the processor is further configured to:

display, based on the security marker, a message on a viewfinder of the electronic device, the message including information associated with the generated image data.

10. The method of claim 1 , wherein the detected security marker includes three or more security markers for defining a security boundary.

11. The method of claim 10 , further comprising:

generating the security boundary based on joining each of the three or more security markers with an adjacent security marker in the three or more security markers; and

identifying an interior image portion circumscribed by the generated security boundary as the image portion to obscure.

12. The method of claim 1 , wherein the security marker includes a coded pattern encoded with specifications defining the security boundary.

13. The method of claim 12 , wherein the coded pattern encoded with specifications defining the security boundary includes a location and dimensions of the security boundary associated with the detected image.

14. The electronic device of claim 5 , wherein the detected security marker includes three or more security markers for defining a security boundary.

15. The electronic device of claim 14 , wherein the processor is further configured to:

generate the security boundary based on joining each of the three or more security markers with an adjacent security marker in the three or more security markers; and

identify an interior image portion circumscribed by the generated security boundary as the image portion to obscure.

16. The electronic device of claim 5 , wherein the security marker includes a coded pattern encoded with specifications defining the security boundary.

17. The electronic device of claim 16 , wherein the coded pattern encoded with specifications defining the security boundary includes a location and dimensions of the security boundary associated with the detected image.

18. The method of claim 1 , wherein modifying the image data includes replacing the image portion circumscribed by the security boundary with unrelated data.

19. The electronic device of claim 5 , wherein the processor being configured to modify the image data includes the processor being configured to replace the image portion circumscribed by the security boundary with unrelated data.
