    A copy-protection system was developed in order to prevent the unauthorized reproduction of photographic prints at a digital print station. The copy-protection system consists of two parts: (1) copy-protected photographic paper manufactured with a latent image of an array of yellow microdots; and (2) digital print stations equipped with software that detects the presence of the microdots in the digital image of a photographic print made on copy-protected photographic paper. The system has a detection rate of 78% and a negligible rate of false detection. ©2000 SPIE and IS&T.
