Very clever, maybe in the future it can be used as second or even third
   authentication factor.

     Users ID'ed through typing, mouse movements

     Continuous authentication app created from DARPA research.
     Researchers have built a continuous authentication platform that can
     accurately identify users based on their typing patterns.
     A series of 90 minute typing tests carried out on 2000 people at
     Iowa State
     University found users could be identified with a half percent
     margin of
     error based on the way they hit keys.
     The work has been spun into an application that could continuously
     authenticate users and lock accounts if another person jumped on the
     computer
     resulting in irregularities being detected. (pdf)
     Uniquely syncopated mouse and keyboard patterns made it possible to
     identify
     users, Iowa State University associate professor Morris Chang said.
     These pauses between words, searches for unusual characters and
     spellings of
     unfamiliar words, all have to do with our past experiences, our
     learning
     experiences, Chang said. And so we call them cognitive fingerprints
     which
     manifest themselves in typing rhythms.
     The system can see if the same person or an imposter is coming in to
     hijack
     the computer."
     The year-long research run together with electrical engineering
     students
     Terry Fang, Kuan-Hsing Ho and Danny Shih received a half a million
     dollar
     grant from the US Defense Advanced Research Projects Agency which
     sought to
     discover if continuous authentication was possible.
     It was now being extended to capture mouse movements and touch
     inputs from
     mobile devices with an additional $1.76 million dollars from the
     agency over
     two years.
