Abstract

La présente invention se rapporte à un procédé et à un système adaptés pour empêcher que des fuites ne se produisent lorsque des conversations entre deux parties sont exécutées via un système de messagerie instantanée. Le procédé selon l'invention comprend les étapes suivantes : un serveur de messages enregistre des données de conversation, plus précisément un contenu de conversation, qui sont reçues d'un terminal de transmission, dans une mémoire dynamique, via l'allocation d'une adresse mémoire ; le serveur de messages transmet alors les données de conversation récupérées à partir de la mémoire dynamique, à un terminal de réception, en se référant à l'adresse mémoire ; et il initialise ensuite l'adresse de la mémoire dynamique. De cette manière, les conversations sont échangées entre les deux parties mais ne sont pas stockées dans le serveur de messages. Selon la présente invention, les données de conversation de services de messagerie mobile ou de services de messagerie instantanée, des services SMS par exemple, ne sont pas stockées par le serveur de messages dans une base de données. Cela élimine le risque qu'une fuite de données de conversation puisse nuire à la confidentialité de données personnelles ou soit récupérée à des fins criminelles.
