First Claim
Patent Images
1. A method comprising:
- using one or more processors;
generating, a random reference string, the random reference string comprising a plurality of alphanumeric characters;
creating an image including the random reference string;
iteratively modifying the image until a distortion criterion is satisfied;
communicating the image to a computer for display to a user together with a time stamp and a checksum, the checksum being generated utilizing the random reference string and the time stamp;
receiving user input data; and
comparing the random reference string and the user input data to detect human interaction with the computer.

Abstract
A system is provided to monitor a user'"'"'s interaction with a computer. The system may comprise a random reference data generator to generate a random reference string, an image generator to create an image including the random reference string, a modification module to iteratively modify the image until a distortion criterion is satisfied, and a communications module to communicate the image to a client computer for display to a user. The random reference string comprises a plurality of alphanumeric characters.
