Title (EN) METHOD AND APPARATUS FOR GENERATING A COVER IMAGE FOR STEGANOGRAPHY
(FR) PROCÉDÉ ET APPAREIL SERVANT À GÉNÉRER UNE IMAGE DE COUVERTURE POUR STÉGANOGRAPHIE
Abstract:
(EN) A method and an apparatus for generating cover images for steganography are provided. The steganographic framework is designed based on an image generation system. The apparatus may encode a message to obtain a binary sequence. The apparatus may obtain a plurality of binary segments of a particular length based on the binary sequence. For each binary segment of the plurality of binary segments, the apparatus may select an image of a semantic content (e.g., a numeral digit) from a dictionary of images of random semantic contents (e.g., random numeral digits) based on the binary segment. The apparatus may combine the selected images to form at least a portion of a cover image denoting a combination of the semantic contents of the selected images (e.g., a plurality of numeral digits).
(FR) L'invention concerne un procédé et un appareil de génération d'images de couverture pour stéganographie. Le cadre stéganographique est conçu sur la base d'un système de génération d'image. L'appareil peut coder un message afin d'obtenir une séquence binaire. L'appareil peut obtenir une pluralité de segments binaires d'une longueur particulière sur la base de la séquence binaire. Pour chaque segment binaire de la pluralité de segments binaires, l'appareil peut sélectionner une image d'un contenu sémantique (par exemple, un chiffre numérique) à partir d'un dictionnaire d'images de contenus sémantiques aléatoires (par exemple, des chiffres numériques aléatoires) sur la base du segment binaire. L'appareil peut combiner les images sélectionnées pour former au moins une partie d'une image de couverture désignant une combinaison des contenus sémantiques des images sélectionnées (par exemple, une pluralité de chiffres numériques).
