BioPassword and Keystroke Dynamics
Red Herring writes about Mark DiSalle and his BioPassword company.
It turns out that measuring the rhythm of your typing then comparing the pattern when someone trie sto log in is an effective method to verify you are (or are not..) who you claim you are.

Known as keystroke dynamics, the technology has its origins in the study of Morse code message patterns sent during World War II. Telegraph operators could recognize who sent the message by its pattern and rhythm. The “Fist of the Sender,” or the uniqueness in the keying rhythm, could distinguish one operator from another.
“We measure the up and down time between each keystroke and also the ‘dwell in flight time,’ which is how long it takes for the finger to get to the next key and how long a finger stays on one key,” says Mr. DiSalle. “We have algorithms that measure in microseconds eight different characteristics of each key.”
I know keyboard dynamics would work with my odd, staccato three finger typing.
But I wish Mark DiSalle and BioPassword would consider branching out into spell correction. My brain to finger wiring results in the space key being pressed one character out of sequence. This type of typo [see paragraph two above!!] is NOT handled well by traditional spell checkers.
