The recent pilfering of PlayStation Network passwords and personal info  shows that having a strong passcode doesn't always guarantee your  online safety. However, key-pattern analysis (KPA) software from  researchers at American University of Beirut may be able to keep our  logins secure even if they're stolen. You create a unique profile by  entering your password a few times while the code tracks the speed and  timing of your keystrokes. The software then associates that data to  your password as another means of authentication. Henceforth, should the  magic word be entered in a different typing tempo, access is denied. We  saw a similar solution  last year, but that system was meant to prevent multiple users from  accessing subscription databases with a single account. This KPA  software allows multiple profiles per password so that your significant  other can still read all your email -- assuming you and your mate reside  in the trust tree, of course.
