Do you ever get that feeling of someone watching you as you try to tap in your PIN code on your smartphone, trying to guess the pattern you make and therefore the digits you type in? Such knowledge would be handy in case said mysterious onlookers have plans to divest you of your device. If so, worry no longer. Cyanogen, Inc. has devised a new unlock feature that will mix up those numbers every time you try to unlock your phone, causing confusion for the would-be thief. And maybe even for you.
