A BeOS application, BHand, was released last year in August at BeBits. Here is the basic description:
"BHand (Bastard Hand) is a new type of user authentication software. BHand doesn't use a password, it "learns" to recognize the users' keyboard typing style. Unlike the use of a password, it should be very difficult to forget (or to lose) your typing style... BHand uses one component of the Think Factory : Braininabox."
I haven't used the application, so I can't comment on its accuracy, but the concept has been around for a while.
Technology doesn't pirate digital content; people pirate digital content.
