Title (EN) METHOD FOR CONTROLLING A CONSUMPTION LIMIT DATE OF DIGITAL CONTENTS DEVICE FOR CONSUMING SUCH CONTENTS, MEANS OF CONTROLLING CONSUMPTION AND SERVER DISTRIBUTING SUCH CONTENTS
(FR) PROCEDE DE CONTROLE DE LA DATE LIMITE DE CONSOMMATION DE CONTENUS NUMERIQUES, DISPOSITIF POUR LA CONSOMMATION DE CES CONTENUS, MOYEN DE CONTROLE DE LA CONSOMMATION ET SERVEUR DISTRIBUANT CES CONTENUS
Abstract:
(EN) This invention relates to a method for controlling the consumption limit date of a digital content which is transferred from distribution means (100) to a consuming device (120) during a temporary connection to be consumed on that device until the limit date, the distribution means (100) having a clock (104), called a reference clock, the value of which at each instant is called the true date. According to this invention, each time the consuming device connects to the distribution means (100), a signal including the true date is transmitted from the distribution means (100) to the consuming device (120) by a secured method to verify that the consumption limit date is not exceeded.
(FR) L'invention concerne un procédé de contrôle de la date limite de consommation indiquée sur un contenu numérique qui est transféré d'un dispositif de distribution (100) à un dispositif de consommation (120) au cours d'une connexion temporaire à consommer sur ce dispositif jusqu'à la date limite. Le dispositif de distribution (100) comporte une horloge (104,) appelée horloge de référence, dont la valeur à chaque moment est appelée la date réelle. Selon cette invention, à chaque fois que le dispositif de consommation se connecte au dispositif de distribution (100), un signal comprenant la date réelle est envoyé du dispositif de distribution (100) au dispositif de consommation (120) par un procédé sécurisé afin de vérifier que la date limite de consommation n'est pas dépassée.
