Abstract
(EN)
A system and method are provided for preventing unauthorized access to electronic data stored on an electronic device (100). A portable licensing medium is configured to communicate with the electronic device for storing license data. The license data is used to determine whether to allow access to the electronic data. A registration authority (10) communicates with the electronic device. The registration authority (110) has a database of verification data for verifying the license data stored on the licensing medium and provides updated license data to the licensing medium.

L'invention concerne un système et un procédé destinés à empêcher l'accès non autorisé à des données électroniques stockées sur un dispositif électronique (100). Un support d'octroi de licence est conçu pour communiquer avec le dispositif électronique afin de stocker des données de licence. Ces dernières sont utilisées pour décider d'accorder ou non l'accès aux données électroniques. Une autorité d'enregistrement (110) communique avec le dispositif électronique et comporte une base de données de vérification destinée à vérifier les données de licence stockées sur le support d'octroi de licence. L'autorité d'enregistrement (110) fournit au support d'octroi de licence des données de licence mises à jour.
