Abstract

L'invention concerne un procédé, un appareil et un système destinés à ajouter un filigrane à un fichier secret, et un support, se rapportant au domaine de l'ajout de filigranes. Le procédé comporte les étapes consistant à: obtenir des informations de contenu sur un écran d'affichage d'un terminal, les informations de contenu comportant un document et une page web (S101); déterminer si le document et la page web comprennent des informations secrètes (S102); et si oui, ajouter des filigranes à des zones secrètes du document et de la page web (S103), les filigranes étant générés par un serveur de génération de filigranes. Le procédé, l'appareil et le système d'ajout de filigrane à un fichier secret, ainsi que le support, peuvent identifier efficacement le caractère secret ou non d'un document et d'une page web sur un écran d'affichage, puis ajouter de façon ciblée des filigranes à des zones secrètes, de façon non seulement à garantir la sécurité d'informations secrètes et à mettre en œuvre un pistage anti-contrefaçon et une protection des droits d'auteur, mais également à permettre à un utilisateur de lire confortablement un contenu à l'extérieur de zones secrètes, améliorant ainsi l'agrément d'utilisation.
