Abstract

La présente invention concerne un procédé pour la distribution sécurisée d'images fixes numériques selon un format nominal issu du codage numérique en ondelettes qui comporte : une étape préparatoire, - une étape de transmission d'un flux principal modifié conforme au format nominal, constitué par les blocs modifiés au cours de l'étape préparatoire et par une voie séparée dudit flux principal d'une information numérique complémentaire permettant de reconstituer le flux original à partir du calcul, sur l'équipement destinataire, en fonction dudit flux principal et de ladite information complémentaire.
