Abstract

Selon l'invention, lors de la réception d'une demande d'initiation d'ouverture de session provenant d'un terminal client (20), un dispositif de fourniture de service de réseau (10) utilise l'un d'une pluralité de numéros stockés de téléphone personnel pour effectuer un appel téléphonique sortant vers un téléphone enregistré (30) d'un utilisateur, qui est le demandeur de la demande d'initiation de service. En outre, le dispositif de fourniture de service de réseau (10) crée des données d'écran pour un écran d'entrée dans lequel une partie du numéro de téléphone personnel à partir duquel l'appel téléphonique sortant a été effectué doit être entré, et transmet les données d'écran au terminal client (20), qui a été la source de transmission de la demande d'initiation de service. Le dispositif de fourniture de service de réseau (10) reçoit alors, en provenance du terminal client (20), un numéro qui a été entré dans l'écran d'entrée, et si le numéro coïncide avec la partie du numéro de téléphone personnel à partir duquel l'appel téléphonique sortant a été effectué, le dispositif de fourniture de service de réseau (10) approuve l'ouverture de session provenant du terminal client (20).
