Abstract

In one implementation, a method for ensuring the trustworthiness of graphical user interfaces is described wherein a computing system user selects and/or modifies an image to be used as at least a portion of the background of one or more visual elements of a graphical user interface of a trusted computing environment. The user selected background image facilitates recognition by the user of the trustworthiness of the environment'"'"'s graphical user interface when it is displayed to the user. The computing system seals the selected image or a modified version of the selected image within the trusted computing environment to prevent access to that image by computing environments other than the trusted computing environment. Additional embodiments are described and claimed.

Claims

1. A method comprising:

selecting an image to mark a trusted computing environment; and

sealing the image to the trusted computing environment.

2. The method of claim 1, wherein the trusted computing environment includes a graphical user interface having at least one visual element, the method further comprising:

using the selected image as at least a portion of the background of the visual element.

3. The method of claim 2, further comprising:

modifying the visual element to make the foreground of the visual element easier to read over the selected image.

4. The method of claim 2, further comprising:

modifying the selected image.

5. The method of claim 4, wherein modifying the selected image comprises adjusting the color saturation.

6. The method of claim 4, wherein modifying the selected image comprises adjusting the brightness.

7. The method of claim 2, further comprising:

modifying the visual element to make the selected image easier to detect.

8. The method of claim 7, wherein modifying the visual element comprises adjusting the transparency of the visual element.

9. The method of claim 2, further comprising:

modifying the visual element and the selected image dependent upon each other to enhance the visual element observation and the selected image detection.

10. The method of claim 2, wherein using the selected image comprises tiling the image to form the background.

11. The method of claim 2, wherein using the selected image comprises stretching the image to form the background.

12. The method of claim 2, wherein using the selected image comprises cropping the image to form the background.

13. A machine-accessible medium including instructions that, when executed, cause a machine to:

isolate a selected image within a trusted computing environment, the trusted computing environment including a graphical user interface having at least one visual element; and

apply the selected image as at least a portion of the background of the visual element.

15. The machine readable medium of claim 13, further including instructions that, when executed, cause a machine to:

modify the selected image.

16. The machine readable medium of claim 15, wherein modifying the selected image comprises adjusting the color saturation.

17. The machine readable medium of claim 15, wherein modifying the selected image comprises adjusting the brightness.

18. The machine readable medium of claim 13, further including instructions that, when executed, cause a machine to:

modify the at least one visual element to make the selected image easier to detect.

19. The machine readable medium of claim 18, wherein modifying the at least one visual element comprises adjusting the transparency of the at least one visual element.

20. The machine readable medium of claim 13, further including instructions that, when executed, cause a machine to:

modify the at least one visual element and the selected image dependent upon each other to enhance observation of the at least one visual element and detection of the selected image.

21. The machine readable medium of claim 13, wherein applying the selected image comprises tiling the image to form the background.

22. The machine readable medium of claim 13, wherein applying the selected image comprises stretching the image to form the background.

23. The machine readable medium of claim 13, wherein applying the selected image comprises cropping the image to form the background.

14. The machine readable medium of claim 14, further including instructions that, when executed, cause a machine to:

modify the at least one visual element to make the foreground of the at least one visual element easier to read over the selected image.

24. An apparatus comprising:

a machine-accessible medium including instructions that, when executed, cause a processor to perform operations comprising;

sealing an image to a trusted computing environment, the trusted computing environment including a user interface having at least one visual element; and

using the image as at least a portion of the background of the at least one visual element.

25. The apparatus of claim 24, wherein the instructions provided by the machine-readable medium further include instructions that, when executed, cause a processor to perform operations comprising:

modifying the image.

26. The apparatus of claim 24, wherein using the image comprises tiling the image to form the background.

27. The apparatus of claim 24, wherein using the image comprises stretching the image to form the background.

28. The apparatus of claim 24, wherein using the image comprises cropping the image to form the background.

29. A system comprising:

a processor to execute instructions; and

a memory coupled to the processor, the memory to store the instructions to be executed by the processor;

wherein, in response to the instructions, the processor performs operations comprising;

sealing an image selected to mark a trusted computing environment to the trusted computing environment, the trusted computing environment including a user interface having at least one visual element; and

using the image as at least a portion of the background of the at least one visual element.

30. The system of claim 29, wherein the processor performs operations further comprising:

modifying the selected image.
