First Claim
Patent Images
1. A method to monitor interaction between a user and a computer, the method including:
- generating an image including, in a random fashion, a random reference data readable by the user, the random reference data comprising a random reference string, the random reference string comprising a plurality of numerical digits;
communicating the image to the computer for display to the user;
receiving user input data; and
comparing the random reference data and the user input data to determine if the user is interacting with the computer, wherein the including of the random reference data includes one of randomly off-centering each digit of the random reference string, providing each digit of the random reference string in a font which is randomly selected, providing each digit of the random reference string in a color which is randomly selected, and adding noise to the image.

Abstract
A method of, and system for, monitoring interaction between a user and a computer is provided. The method includes generating an image including random reference data readable by the user, and communicating the image to the computer for display to the user. User input data is then received and a comparison between the random reference data and the user input data is performed to determine if the user is interacting with the computer.
