VISUAL OR TOUCHSCREEN PASSWORD ENTRY

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 and movement of either the modified base image or modified overlay image is permitted if a criterion for movement is met. Positive authentication is indicated in response to the base image reference point on the modified base image being aligned with the overlay image reference point on the modified overlay image.
