Abstract

A method of authenticating access on an electronic device. A digital image overlaid by an array of alphanumeric characters is displayed on a three-dimensional display of the electronic device. The digital image includes a three-dimensional representation of a scene and is displayed in three-dimensional coordinates. The array of alphanumeric characters is positioned on the three-dimensional display with respect to the digital image in three dimensions in response to received input. Access to the electronic device is authenticated in response to detecting that a designated character in the digital image is aligned with a designated object in the digital image.
