Abstract
(EN)
There are provided an information distribution system, a node device, a release data issuing method, and the like capable of preventing application of an excessive processing load on a particular device such as a server while assuring safety associated with copyright protection. The information distribution system includes a plurality of node devices which can communicate with one another via a network. A plurality of distribution information whose reproduction is limited are distributed and stored in the node devices. An authentication processing associated with permission of issuance of release data for releasing the reproduction limit of the respective distribution information is distributed and performed in the node devices.

L'invention concerne un système de distribution d’informations, un dispositif nœud, une méthode d’émission de données de publication et similaire pouvant éviter l’application d’une charge de traitement excessive à un dispositif en particulier tel un serveur tout en assurant la sécurité associée à la protection de droits d’auteur. Le système de distribution d’informations comprend une pluralité de dispositifs nœuds pouvant communiquer les uns avec les autres par un réseau. Une pluralité d’informations de distribution dont la reproduction est limitée est distribuée et stockée dans les dispositifs nœuds. Un traitement d’authentification associé à la permission d’émission de données de publication pour publier la limite de reproduction des informations de distribution respectives est distribué et effectué dans les dispositifs noeuds.
