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.
