Abstract
(EN) A content distribution system is described herein which enables a data owner of content to set one or more restrictions on a data consumer where the one or more restrictions need to be satisfied by a data consumer device before the data consumer has 5 access to the content. In addition, the content distribution system's components are described herein which include a data owner device, a key server, a data consumer device, a data producer device, and a content server.
(FR) L'invention concerne un système de distribution de contenu qui permet à un propriétaire de données de contenu de définir une ou plusieurs restrictions sur un consommateur de données, la ou les restrictions devant être satisfaites par un dispositif consommateur de données avant que le consommateur de données ait accès au contenu. De plus, l'invention concerne des composants du système de distribution de contenu qui comprennent un dispositif propriétaire de données, un serveur de clés, un dispositif consommateur de données, un dispositif producteur de données et un serveur de contenu.
