Abstract
A method of user authentication on 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 responsive to receiving an input starting outside a display area of a touchscreen. 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.
Claims19
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 selected base image reference point, and the overlay image having a selected overlay image reference point, which when executed by a processor direct the computing device to:
- generate a modified base image;
- generate a modified overlay image;
- display, on a display area of a touchscreen, the modified base image overlaid by the modified overlay image;
- receive an input, the input starting outside the display area of the touchscreen and at least an initial portion of the input being received from a touch-sensitive border around the display area;
- move the one of the modified base image and the modified overlay image only in response to receiving the input;
- and
- in response to alignment of the base image reference point on the modified base image with the overlay image reference point on the modified overlay image at a point on the display area after the move, indicate positive authentication.
A method of 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 selected base image reference point, and the overlay image having a selected overlay image reference point, the method comprising:
- generating a modified base image;
- generating a modified overlay image;
- displaying, on a display area of a touchscreen, the modified base image overlaid by the modified overlay image;
- receiving an input, the input starting outside the display area of the touchscreen and at least an initial portion of the input being received from a touch-sensitive border around the display area;
- moving the one of the modified base image and the modified overlay image only in response to receiving the input;
- and
- in response to alignment of the base image reference point on the modified base image with the overlay image reference point on the modified overlay image at a point on the display area after the moving, indicating positive authentication.

- one or more 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 selected base image reference point, and the overlay image having a selected overlay image reference point, the method including:
- generating a modified base image;
- generating a modified overlay image;
- displaying, on a display area of a touchscreen, the modified base image overlaid by the modified overlay image;
- receiving an input, the input starting outside the display area of the touchscreen and at least an initial portion of the input being received from a touch-sensitive border around the display area;
- moving the one of the modified base image and the modified overlay image only in response to receiving the input;
- and
- in response to alignment of the base image reference point on the modified base image with the overlay image reference point on the modified overlay image at a point on the display area after the moving, indicating positive authentication.
