snoop onto them as they snoop onto us

analyzing the sounds of keystrokes to tell what's being typed (with something like 96% accuracy).

creepy, though interesting.

for some reason it reminds me of an idea i once read about for a biometric security feature that would continuously run a hash of certain of the users physical input parameters--i.e. the rhythm of your typing or the way you move your mouse around.

better than a password because it's harder to steal--you have to fake it--and also because it keeps working the whole session, in the background, so, if an intruder did somehow manage to breach security, if the computer realizes that the biometric usage patterns don't match, then the session can be interrupted--something that can't really happen with a password.
