Abstract:

Southwest Research Institute SwRI developed a novel method for authenticating a computer user s identity by deploying covert games disguised as anomalous computer functionality. The method applies game theory principles to allow users to develop unique strategy paths for playing the imperceptible games. By examining users subconscious game playing strategies, the team captured discriminatory information without sophisticated contextual analysis or explicit communicative behavior. This approach complements many other cognitive fingerprint detection methods and could be used to help increase the overall accuracy of a system of combined biometric modalities. The technical approach for this research project included three major phases Analysis, Design and Development, and Final Evaluation.
