On Jan. 15th, 2012, John Keller wrote for Military & Aerospace Electronics on a new DARPA initiative that would shift the DOD away from CAC cards (which, as we recently learned, the Chinese may have compromised). Keller writes that DARPA wants to develop a "software-based biometric approach" for DOD computer systems. That approach would require biometric based user identification at both login and "throughout the courses of the user's computer sessions."
What would some of these biometric approaches look like? The article mentions tracking how the user searches for information, how the user reads information, how the user's eye scans the page, and keystrokes, among others. These identifiers create "a cognitive footprint" that would allow for more secure authorization.
