A combination of software and hardware renders the computer screen
incomprehensible to onlookers. The software consists of a computer
program that scrambles the organization of the image on the computer
screen. The hardware consists of a set of glasses that reorganizes the
scrambled image on the computer screen so that the authorized user can
comprehend the image. In an alternate embodiment, the scrambled image is
transmitted by cable or wireless transmission to a set of display glasses
with an embedded personal display computer that unscrambles the image for
viewing at the display glasses.
