Multi-layer multi-point or randomized passwords

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 a first point relative to the base image reference point being aligned with a second point relative to the overlay image reference point.
