Title
(EN) DATA-HIDING WATERMARKS
(FR) FILIGRANES DE DISSIMULATION DE DONNÉES
Abstract
(EN) A method of forming a data-hiding watermark on a surface may include encoding data within an image using the chrominance data of the of the image, adjusting at least one characteristic of the image to enhance the prominence of the encoded data within the image, and printing the adjusted, encoded image onto the surface.
(FR) Un procédé de formation d'un filigrane de dissimulation de données sur une surface peut consister à coder des données à l'intérieur d'une image à l'aide des données de chrominance de l'image, ajuster au moins une caractéristique de l'image pour améliorer la proéminence des données codées dans l'image, et imprimer l'image codée, ajustée, sur la surface.
