Abstract

Systèmes, méthodes et logiciel permettant dassurer une sécurité numérique à un message enfant transmis dun dispositif mobile à un serveur de messagerie, ledit dispositif mobile ne transmettant généralement pas au serveur de messagerie le message parent avec le message enfant. On détermine sil faut appliquer une sécurité numérique, comme un codage ou une signature numérique, ou les deux, et, si le dispositif mobile ne comporte pas de copie complète dun message parent à insérer dans le message enfant, alors le dispositif mobile télécharge de façon sélective le message parent à partir du serveur de messagerie avant dentrer le traitement dune signature numérique ou avant le codage. Les systèmes et méthodes peuvent également prévoir une vérification de la taille du message enfant, lorsque le message enfant comprend du contenu parent inséré, pour veiller à ce que le message enfant ne dépasse pas une limite prescrite pour ce qui est de la taille du message.
