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.
