Password entry using 3D image with spatial alignment

摘要

A method of authenticating a user of a computing device is proposed, together with computing device on which the method is implemented. In the method a modified base image is overlaid with a modified overlay image on a display. At least one of the modified base image and modified overlay image is moved by the user. Positive authentication is indicated in response to the base image reference point on the modified base image being aligned, at least one of the base image reference point and the overlay image reference point having coordinates in three dimensions.

主权项

1. One or more non-transitory computer readable media having computer readable instructions stored thereon for authenticating a user of a computing device, the computing device having a memory storing a base image and an overlay image, the base image having a particular base image reference point, and the overlay image comprising a plurality of objects and having a particular overlay image reference point, the instructions, which when executed by a processor direct the computing device to:
generate a modified base image having the particular base image reference point; generate a modified overlay image having the plurality of objects and the particular overlay image reference point; display, on a display, the modified base image overlaid by the modified overlay image; receive an input for moving one of the modified base image and the modified overlay image; move the one of the modified base image and the modified overlay image in response to the input; and in response to alignment of the particular base image reference point with the particular overlay image reference point on the display, indicate positive authentication, the particular base image reference point or the particular overlay image reference point having coordinates in three dimensions.
