Patent

CA 2489529

The invention relates to establishing trust between parties (32, 30, 38) prior to a multiparty communications session over the Internet or the like. This is achieved by the exchange of messages describing user roles required to be performed during a session, and the assumption of the described roles by the parties (30, 32, 38) to a session. The assumption of a role is non-repudiable via the use of digital signatures, in that a party (32, 30, 38) must digitally sign the message or part thereof which indicates that it intends to assume a role. The roles relate to control functions to be performed during the session, such as Quality of Service determiner (30), or Quality of service signaller (38).

L'invention concerne la constitution d'un groupe entre des parties (32, 30, 38), préalablement à une session avec communications multipartites sur Internet ou analogue. Ce résultat est obtenu par l'échange de messages décrivant aux utilisateurs les rôles requis durant une session, et l'acceptation des rôles décrits par les parties (30, 32, 38) pour une session. L'acceptation d'un rôle est non répudiabe via l'utilisation de signatures numériques, du fait qu'une partie doit signer numériquement le message ou une partie de celui-ci, spécifiant qu'il a l'intention d'assumer un rôle. Les rôles ont trait aux fonctions de contrôle à exécuter durant la session, telles que la qualité du détermineur de service (30), ou la qualité du signaleur de service (38).
