A system and method for enhancing the protection of digital properties while also increasing the flexibility of distribution of the digital properties. In one embodiment, the digital property is protected through the binding of at least one unique client device identifier with the digital property prior to distribution. Decryption at a client device would therefore be dependent on a comparison of the unique client device identifier that is extracted from the encrypted digital property with a unique client device identifier of the device that is seeking to access the digital property.
L'invention concerne un système et un procédé destinés à améliorer la protection de contenus numériques tout en augmentant la souplesse de distribution des contenus numériques. Dans un mode de réalisation, le contenu numérique est protégé par association d'au moins un identificateur de dispositif client unique au contenu numérique avant la distribution. Par conséquent, le déchiffrement au niveau d'un dispositif client est dépendant d'une comparaison entre l'identificateur de dispositif client unique extrait du contenu numérique chiffré et un identificateur de dispositif client unique du dispositif cherchant à accéder au contenu numérique.
