Graphical event-based password system
First Claim
Patent Images
1. An event-based graphical password system comprising:
- a display;
first means, responsive to the initial request of the user, for displaying on the display a set of images;
second means, that allows the user to indicate selection of particular image of the set of images on said display;
a logic unit;
a first memory register to hold a code representing the first image selected and accessible by said logic unit;
a second memory register to hold a code representing the second image selected and accessible by said logic unit;
a third memory register to hold a code representing the third image selected and accessible by said logic unit;
third means that forwards the contents of said first, second and third memory registers to another memory device or to another computer system where the contents of the said first, second and third memory registers represent the password chosen by the user;
a program memory accessible by said logic unit holding a stored computer program which causes the logic unit to respond to the user'"'"'s initial image selection by displaying a second set of images, and which in turn responds to the user'"'"'s second image selection by displaying a third set of images.

Abstract
An event-based graphical password system displays sets of images and requires the user to select an image corresponding with an event in a story the user imagines. This causes a second set of images to be displayed, which requires the user to select a second image, again corresponding with an event in a story the user imagines. This causes a third set of images to be displayed which requires the user to select a third image, against corresponding with an event in a story the user imagines. Codes representing these images are placed in a series (or virtual) scene registers, which together, represent the password selected by the user.

7. A method of an event-based graphical password system for setting passwords comprising the steps of:
-
in response to a start-program condition or to an initial request of a user, displaying to the user one or more images;
selecting an image based on a story event the user has imagined;
in response to the selected image, displaying to the user one or more different images;
selecting another image based on the events of a story the user has imagined;
in response to the selected second image, displaying to the user one or more different images;
selecting a third image based on the events of a story the user has imagined;
in response to the selected third image forwarding the codes stored in three memory registers representing the selected images to another memory location. - View Dependent Claims (8, 9, 10)
