Abstract

L'invention concerne un procédé de protection d'informations d'IM, comprenant les étapes suivantes consistant : à recevoir une demande d'envoi déclenchée par une première fenêtre de conversation en ligne d'une extrémité d'envoi, à acquérir des informations d'IM dans la demande d'envoi, et à établir une fenêtre de conversation en ligne en nuage correspondant aux informations d'IM ; à déterminer, en fonction d'informations associées de la première fenêtre de conversation en ligne, si un mode de conversation en ligne limité dans le temps de la fenêtre de conversation en ligne en nuage est activé ; si le mode de conversation en ligne limité dans le temps est activé, à chiffrer les informations d'IM dans la fenêtre de conversation en ligne en nuage selon une règle de chiffrement prédéfinie ; à envoyer les informations d'IM chiffrées à une seconde fenêtre de conversation en ligne d'une extrémité de réception, et à surveiller l'état de lecture des informations d'IM dans la seconde fenêtre de conversation en ligne ; et à supprimer les informations d'IM dans la première fenêtre de conversation en ligne et/ou dans la seconde fenêtre de conversation en ligne après que la lecture des informations d'IM a été détectée. L'invention concerne également un dispositif et un appareil de protection d'informations d'IM, et un support d'informations d'ordinateur.
