Abstract

L'invention concerne un procédé pour le paiement par période de temps d'un contenu de données dans un système de communication ou de distribution. Un premier utilisateur et un second utilisateur acceptent des frais par période de temps pour un contenu de données. Un dispositif informatique associé à un second utilisateur commence la transmission dudit contenu de données. Un service de traitement vérifie si ledit premier utilisateur a ou non un crédit suffisant dans un compte associé audit premier utilisateur pour une période de temps suivante. En réponse au fait que ledit premier utilisateur a un crédit insuffisant pour une période de temps suivante, la réception par ledit premier utilisateur dudit contenu de données est terminée. En réponse au fait que ledit premier utilisateur a un crédit suffisant pour une période de temps suivante, le dispositif informatique dudit second utilisateur transmet ledit contenu de données à un ou plusieurs dispositifs informatiques d'homologue, qui retransmettent ledit contenu de données à d'autres dispositifs informatiques d'homologue, jusqu'à ce que ledit contenu de données soit transmis au dispositif informatique dudit premier utilisateur ; lesdits dispositifs informatiques d'homologue signalent la réception dudit contenu de données audit service de traitement ; ledit service de traitement reçoit lesdits signaux de réception à partir d'au moins certains desdits dispositifs informatiques d'homologue ; ledit service de traitement valide lesdits signaux de réception reçus ; et ledit service de traitement met à jour des comptes associés audit premier utilisateur et audit second utilisateur.
