Abrégé
(EN)
A system and process for the concealment of digital content recorded on a storage medium such as a compact disc (CD) and, more specifically, to an apparatus and method for recording a CD (106) or other storage medium using a recording drive (102), such as a CD-R or CD-RW drive, that is connected to a computer (101) and that conceals the stored digital content (110, 112) on the medium from being read by a compact disc read-only memory (CD-ROM) or other digital-based reader or computer device, for example as done when performing digital audio extraction (also known as ripping) of musical content from an audio CD (108). The apparatus and method permit improved control of the usage and copying of published content on physical media by an immediate purchaser while limiting copying and distribution of the content to unauthorized recipients.
(FR)
L'invention porte sur un système et un procédé permettant de dissimuler le contenu numérique enregistré sur un support tel qu'un CD, et plus spécifiquement sur un appareil et un procédé d'enregistrement, sur un CD ou autre support par un enregistreur du type CD-R ou CD-RW relié à un ordinateur, permettant de dissimuler le contenu numérique enregistré pour empêcher sa lecture par un lecteur de CD-ROM ou tout autre lecteur numérique ou dispositif ad hoc, comme cela se fait par exemple lorsqu'on extrait (par piratage) des données audio numériques correspondant au contenu musical du CD. L'appareil et le procédé permettent un meilleur contrôle de l'utilisation et de la copie du contenu d'un support physique par un acheteur intermédiaire tout en limitant sa copie, et sa distribution à des personnes non agrées.
