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.

I wonder how such a system could deal with illness, injury, exhaustion, transitioning between languages, etc.
However, I agree that research would be interesting; it’s quite possible they’ll find something with low enough failure rates to use.
