Definition: keyboard biometrics

An authentication method that uses the rhythm of a person's typing on the computer. The "dwell time" between pressing a key down and letting it up, as well as the "flight times" between one key down and the next key down and one key up and the next key up, produce a rhythm unique to the individual. This rhythm is recorded when typing in username and password and compared against future logins. See biometrics and biometric signature.
