Title (EN) ABSORPTIVE COATING ON A DISC TO CREATE A REFLECTIVE MODULATION FOR ENCRYPTION
(FR) REVETEMENT ABSORBANT APPLIQUE SUR UN DISQUE POUR CREER UNE MODULATION DE REFLEXION A DES FINS DE CODAGE
Abstract:
(EN) . Described herein are systems and methods for digital data encryption, and more specifically, systems and methods for providing encryption keys for reading encrypted data. Optical media, particularly digital disks, are described where a laser reader accesses digital data on a disk. The disks are coated with a coating containing an encryption key to access encrypted data in the digital disk.
(FR) L'invention concerne des systèmes et des procédés de codage de données numériques, et plus particulièrement, des systèmes et des procédés de création de clés de codage pour la lecture de données codées. Des supports optiques, en particulier des disques numériques, sont décrits, un lecteur laser donnant accès aux données numériques présentes sur un disque. Les disques sont pourvus d'un revêtement contenant une clé de codage donnant accès aux données codées dans le disque numérique.
