Abstract
Aujourd'hui, une grande partie de la propriété intellectuelle est traitée numériquement, sous forme de flux de données ou de fichiers audio, vidéo ou audio-vidéo. Avec les équipements électroniques et les réseaux de communication actuels extrêmement puissants, tels que le réseau Internet, ce contenu numérique peut être reproduit de façon remarquable et distribué sans aucun contrôle. Malgré des tentatives de protection de ce type de contenu numérique, aucune des techniques de protection existantes n'a porté ses fruits. L'invention porte sur un système et un procédé permettant de protéger un contenu numérique en intégrant ce contenu dans un progiciel exécutable, tel qu'un lecteur de contenu multimédia, en exécutant un mécanisme de protection (tel qu'un mot de passe, un filigrane ou une protection par cryptage), puis en codant le progiciel dans une forme inviolable. De cette manière, on peut utiliser le contenu numérique en lançant le progiciel exécutable dans lequel il a été codé. En revanche, on ne peut pas accéder au contenu lui-même ni percer le mécanisme de protection.
