L’évolution récente des communications sans fil a permis de multiplier les transmissions de contenus numériques. En ce qui concerne la distribution de contenus multimédias, les pirates informatiques sont enthousiastes à l’idée de lire, de copier et d’adapter les informations informatisées sans effort. Ce livre présente un filigrane vidéo utilisant l’approche de l’entrelacement pour améliorer la sécurité et la robustesse. Une couche de luminance de trames est partagée en deux rangées paires et impaires d’une image. Ce processus est appelé entrelacement. En outre, il s’agit de désentrelacer en supprimant les rangées nulles et en égalisant les deux parts. Le filigrane est alors dissimulé dans n’importe laquelle des parts par la transformée en ondelettes. Ainsi, les informations du filigrane sont demandées avec satisfaction par le système visuel humain, ce qui les rend indétectables. Les résultats des tests démontrent que le filigrane est efficace pour la protection du contenu, ce qui est proche de la qualité des normes requises pour les applications multimédias. En outre, d’autres orientations possibles pour le développement de ces techniques sont décrites.
