Techniques for making and using recoverable marks for films. The recoverable mark consists of a portion of a film to which a watermark that is imperceptible to viewers of the film has been applied and an original mark that is applied to the portion of the film with the watermark. Application of the original mark to the portion modifies the watermark, and consequently, if the original mark is altered, the modifications to the watermark preserve the original mark. In one application of the technique, the watermark is applied to a digital master of the film, a master analog copy is made from the digital master, and a unique original mark is applied to each of the copies made from the master analog copy.

L'invention concerne des techniques permettant de produire et d'utiliser des marques pour films récupérables. Une marque récupérable comprend une partie de film sur laquelle on a appliqué un filigrane imperceptible à des observateurs du film et une marque originale appliquée sur la partie de film comprenant le filigrane. L'application de la marque originale à la partie filigranée permet de modifier le filigrane et donc, en cas d'altération de la marque originale, les modifications apportées au filigrane permettent de préserver la marque originale. Dans une application de cette technique, le filigrane est appliqué à l'original numérique du film, une copie analogique maître est produite à partir de cet original numérique et une marque originale unique étant appliquée à chacune des copies produites à partir de la copie analogique maître.
