Abstract:
A system that deters an unauthorized person from viewing the image in the display of a handheld electronic device. The handheld electronic device has a touch screen display. A touch security parameter requires a person to repeatedly tap the touch screen display with one or two fingers. The touch screen display will only accurately display an image for as long as the tapping continues. A camera security parameter senses the location of a face in the field of view of a camera. The touch screen display will only accurately show the image for as long as a face is detected in the camera's field of view. A position security parameter detects pitch and yaw with respect to the downward direction of gravity. The touch screen display will only accurately show the image for as long as the display is held within a range of acceptable positions.
