If a hacker can break into the computer and steal these pictures, they can be displayed on the screen of a laptop, held up to the camera, and ... you guessed it. Systems of greater sophistication watch to see whether the picture moves as a live person does. The testers took a short video clip of an authorized person, held it in front of the camera on a laptop, and ... bingo.

    Well, how about fingerprints? More bad news. When you put your finger on the reader, your print remains there after you leave.
