Password entry using 3d image with spatial alignment

An electronic device, comprising:

• a processor;
• a display coupled to the processor;
• a memory coupled to the processor storing instructions that, when executed by the processor, cause the processor to:
• generate a modified first image from a first image, wherein the first image and the modified first image include a first image reference point;
• generate a modified second image from a second image, wherein the second image and the modified second image include a second image reference point;
• display a three dimensional representation of the modified first image overlaid by the modified second image;
• authenticate access to the electronic device in response to substantial alignment of the first image reference point in the modified first image with the second image reference point in the modified second image.

A non-transitory machine readable medium having tangibly stored thereon executable instructions that, when executed by a processor of an electronic device, cause the electronic device to perform a method of controlling access to the electronic device, the method comprising:

• generating a modified first image from a first image, wherein the first image and the modified first image include a first image reference point;
• generating a modified second image from a second image, wherein the second image and the modified second image include a second image reference point;
• displaying a three dimensional representation of the modified first image overlaid by the modified second image;
• authenticating access to the electronic device in response to substantial alignment of the first image reference point in the modified first image with the second image reference point in the modified second image.
