DARPA behavioral biometrics - "biometrics that can be captured through the technology we already use"

DARPA involvement in behavioral biometrics. Key quote: "The first phase of the program will focus on researching biometrics that do not require the installation of additional hardware sensors, rather the program will look for research on biometrics that can be captured through the technology we already use looking for aspects of this “cognitive fingerprint.” These could include, for example, how the user handles the mouse and how the user crafts written language in an e-mail or document. A heavy emphasis will be placed on validating any potential new biometrics with empirical tests to ensure they would be effective in large scale deployments."
