Patent ID: 8542251

Claim:
A computer-implemented method, comprising: receiving, from a user, angle orientations of multiple images corresponding to positions occupied by each of the multiple images, wherein the angle orientations define a preset orientation for each of the positions occupied by the multiple images independent of particular images occupying each of the positions; presenting to the user multiple images with each of the images occupying one of the positions; receiving a rotational reorientation of the multiple images occupying each of the positions by the user, wherein the multiple images are freely rotatable through 360 degrees by the user; and providing access to a computing service based on a comparison of the orientations of the multiple images in each position after reorientation by the user to the preset orientation set by the user for each of the positions occupied by the multiple images, wherein access to the computing service is provided if the orientations of the images are within a predetermined angle of the preset orientation set by the user for each of the positions occupied by the multiple images.
