Abstract

L'invention concerne essentiellement un système de fichier RFID réparti et un procédé d'accès transparent à des données réparties sur un ou plusieurs transpondeurs, plusieurs transpondeurs RFID pouvant être regroupés sous forme d'ensemble présentant une capacité de stockage augmentée en conséquence, et un ensemble présentant respectivement deux types d'étiquettes RFID, c.-à-d. des transpondeurs de gestion d'ensemble destinés à l'organisation et des transpondeurs de données d'ensemble destinés au stockage des ensembles de données. Ceci permet d'obtenir un accès transparent et rapide à des données, une adaptation économique et rapide de la capacité de stockage des transpondeurs par ajout ou retrait d'étiquettes RFID inscriptibles et une meilleure robustesse des données, notamment du fait du stockage réparti.
