Abstract
A security method and system for protecting movie film images from being recorded by video cameras. The system is comprised of a means to generate an infrared pattern and a means to display this infrared pattern. The infrared pattern generated and displayed is of sufficient strength such that video cameras with infrared filters can not prevent the infrared pattern from interfering with the recording. A human viewing a screen containing movie film images sees only the movie film images on the screen and does not see the infrared pattern being displayed simultaneously. Video cameras aimed to record a screen containing the movie film images, even video cameras having infrared filters, are unable to prevent the infrared pattern from interfering with recording the movie film images, and one embodiment may completely obscure the picture being recorded and render it unacceptable for even pirated distribution.
