biometric identification by typing pattern has shown up in science fiction
from time to time. Now we will see a new kind of superhero : instead of a
shapeshifter, a man who can effortlessly mimic the typing patterns of
others, smoothly taking over their identities, skipping from host to host
as the city sleeps.
No, seriously, this gets at the question of how to prevent false negatives
(rejecting you when you are in a fit of rage - although maybe that isn't
so bad :) without increasing false positives (allowing someone to do a
poor imitation of you and get away with it). Presumably these guys believe
they have an acceptable solution. Hopefully they've thought about this.
We'll see what happens...
