La possibilité d’ajouter plusieurs filigranes à la même image permettrait de nombreuses applications intéressantes telles que la traçabilité des documents multimédias, la surveillance de l’utilisation des données et la gestion de propriétés multiples. Ce livre présente un nouveau système de filigrane qui permet d’insérer et de détecter de manière fiable plusieurs filigranes incorporés de manière séquentielle dans une image numérique. La méthode proposée, basée sur l’algèbre linéaire élémentaire, est asymétrique, sûre en cas d’attaque par projection et résistante aux distorsions dues aux opérations de base telles que le stockage, la transmission et la conversion de format. Le filigrane numérique est un processus de modification d’un support physique ou électronique en vue d’y intégrer un code lisible par une machine. Le support peut être modifié de manière à ce que le code incorporé soit imperceptible ou presque imperceptible pour l’utilisateur, mais il peut être détecté par un processus de détection automatisé.
