<p>User keystrokes and keystroke timings are continually captured during computer use. The captured keystrokes and timings are compared with a user profile of keystrokes and timings. A statistical analysis determines what should be in the profile and how the captured keystrokes and timings match up with the stored ones. An error action is initiated if the statistical analysis indicates that the user is not the one who is supposed to be using the computer.</p> |
