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.
