Authentication by "Cognitive Footprint"
DARPA is funding research into new forms of biometrics that authenticate people as they use their computer: things like keystroke patterns, eye movements, mouse behavior, reading speed, and surfing and e-mail response behavior. The idea -- and I think this is a good one -- is that the computer can continuously authenticate people, and not just authenticate them once when they first start using their computers.
I remember reading a science fiction story about a computer worm that searched for people this way: going from computer to computer, trying to identify a specific individual.
