If you've used Windows 8, or even just seen the ads for it, you'll
     know it has a feature called Picture Passwords.

     You choose a picture, any picture, and then "annotate" it with three
     finger movements: you can tap a point, draw a stroke, or sweep a
     circle.

     The picture helps you to remember where you made the gestures, so
     you can repeat them reliably enough to pass the test and unlock your
     device.

     If you have a touch screen tablet, Picture Passwords are
     surprisingly handy. (Pun intended.)

     But how safe are they?
