Abstract

Embodiments described herein relate to a device operable to process input for a picture password for proof of knowledge. In some embodiments, the device includes a display, an input subsystem, processor(s), and memory containing instructions executable by the processor(s) such that the device is operative to display, on the display of the device, an image for the picture password proof of knowledge. The image is associated with an overlaid grid comprising a plurality of elements, and each element corresponds to a distinct area of the image. The device is further operative to, determine an offset to be used and, in response to receiving an input via the input subsystem at a first location of the display, highlight an element of the overlaid grid at a second location on the first image on the display. The second location is offset from the first location by the offset.

Claims

1. A device, comprising:

a display;

an input subsystem;

one or more processors; and

memory containing instructions executable by the one or more processors whereby the device is operable to;

display, on the display of the device, a first image, wherein the first image is associated with an overlaid grid comprising a plurality of elements and each element corresponds to a distinct area of the image;

determine an offset to be used; and

in response to receiving an input via the input subsystem at a first location on the first image on the display, highlight an element of the overlaid grid at a second location on the first image on the display, wherein the second location is offset from the first location by the offset.

2. The device of claim 1, wherein the first location is located within the first image.

3. The device of claim 1, wherein the device is further operable to:

display a white space area along an outer edge of the displayed image, wherein the first location is located within the white space area.

4. The device of claim 1, wherein the input subsystem comprises a touch-sensitive display.

5. The device of claim 1, wherein the offset is determined based on a saved offset value.

6. The device of claim 1, wherein the offset is determined based on a detected touch diameter.

7. The device of claim 1, wherein the offset is determined by the device being operable to:

in response to receiving a training input via the input subsystem at a first training location on the first image on the display, continually change a highlighted element of the overlaid grid until the training input is concluded where the highlighted element is at a second training location on the first image on the display;

set the offset to be the difference between the first training location and the second training location.

8. The device of claim 1, wherein the offset is set based on whether or not the device is a handheld mobile device and the input subsystem comprises a touch-sensitive display.

9. The device of claim 1, wherein the device is further operable to display, on the display of the device, the overlaid grid comprising the plurality of elements.

10. The device of claim 1, wherein the device is further operable to not display, on the display of the device, the overlaid grid comprising the plurality of elements.

11. The device of claim 1, wherein the device further comprises a clock subsystem, and the input activates or deactivates a predetermined timer controlled by the clock subsystem.

12. The device of claim 1, wherein the input is selected from a group consisting of a touch input, a mouse input, and a hover input.

13. The device of claim 12, wherein the input is selected from a group consisting of a down input, a move input, and an up input.

14. The device of claim 13, wherein the device further comprises a clock subsystem, and the device is further operable to determine a state of a predetermined timer controlled by the clock subsystem.

15. The device of claim 14, wherein, if the input is a down input, the device is further operable to:

if the predetermined timer is active;

designate the element of the overlaid grid at the second location as a prospective end-point for an input action; and

if the predetermined timer is inactive;

designate the element of the overlaid grid at the second location as a prospective start-point for the input action.

16. The device of claim 15, wherein the device is further operable to:

if the element of the overlaid grid at the second location is designated as the prospective end-point, display a line between a start-point of the input action and the prospective end-point for the input action.

17. The device of claim 13, wherein the device is further operable to:

determine a designation of the element of the overlaid grid at the second location on the first image, wherein the designation is selected from a group consisting of a prospective start-point for an input action and a prospective end-point for the input action.

18. The device of claim 17, wherein, if the input is a move input, the device is further operable to:

if the designation of the element of the overlaid grid at the second location on the first image is the prospective start-point for the input action;

move the prospective start-point in accordance with the move input; and

if the designation of the element of the overlaid grid at the second location on the first image is the prospective end-point for the input action;

move the prospective end-point in accordance with the move input.

19. The device of claim 18, wherein the device is further operable to:

if the designation of the element of the overlaid grid at the second location on the first image is the prospective end-point for the input action, move, on the display, a line between a start-point for the input action and the prospective end-point in accordance with the move input.

20. The device of claim 17, wherein, if the input is an up input, the device is further operable to:

if the designation of the element of the overlaid grid at the second location on the first image is a prospective start-point for the input action;

set the element of the overlaid grid at the second location as a start-point for the input action, and activate the predetermined timer; and

if the designation of the element of the overlaid grid at the second location on the first image is a prospective end-point for the input action;

set the element of the overlaid grid at the second location as an end-point for the input action.
