Abstract

Système de gestion d'accès à des données qui permet d'empêcher efficacement l'accès illégal à des données. Ledit système est doté d'un système d'enfouissement d'informations de gestion d'accès dans lequel les informations de gestion d'accès aux données sont préparées, puis sont enfouies dans les données par déformation des données sans changement de leur qualité. La présente invention concerne un procédé de gestion d'accès à des données dans lequel les informations de gestion enfouies dans les données par déformation des données, sans changement de la qualité desdites données, sont extraites et l'accès aux données est géré selon les informations extraites. La présente invention concerne également un procédé permettant de modifier l'accès à des données selon le type de support (RAM ou ROM) sur lequel les données sont stockées. Lesdites informations de gestion comprennent les informations de commande d'enregistrement, de réception, de reproduction, d'entrave de sortie, de copiage de l'historique des données ou de changement des informations de gestion. Selon le présent procédé, on peut empêcher le copiage illégal, etc., de données, ce qui permet de protéger efficacement une oeuvre littéraire.
