This article presents a new approach for security management in digital cinema applications. Metameric blacks are used as a new try for cinematic-film protection procedures, which are used in theatre projection systems. The information given by the capturing device it? production time decomposes to its base spectra and makes an unacceptable image quality for camcorders by adding a specific metameric black to it. This procedure takes place during the exhibition, and the camcorders take poor quality pictures although the image may not have any changes hi its quality for the audience. This try tends to reach the goal of security management during the movie plays and may be a new method to keep the rights of producers against digital theft. (c) 2008 Wiley Periodicals. Inc.
