Abstract

La présente invention concerne des systèmes et des procédés de masquage de données sur des réseaux publics. Au niveau d'un nud de publication, le système peut administrer des champs d'entrée de données d'une page Internet et intercepter et coder un contenu, comme du texte, des images et une entrée vidéo au niveau des champs d'entrée de données, avant que le contenu ne soit publié en ligne sur un site Internet du fournisseur de services publics. Une politique peut être définie pour contrôler ceux des utilisateurs qui ont un accès autorisé à une clé pour décoder le contenu codé. La politique peut renvoyer vers un nud de politique de tiers en déterminant un accès par clé. Un compte d'une entité de contrôle, telle qu'un gardien ou un employeur, peut être configuré pour contrôler l'état de codage de publications effectuées par un autre accès par clé et de décodage. Un agent de confidentialité peut traiter le contenu de champ d'entrée pour tenter de détecter des marqueurs de codage dans le contenu de champ d'entrée, lesquels marquent le contenu à coder. Un serveur de clé de tiers peut être utilisé pour mémoriser les clés de décodage. Une référence d'URI à la clé de décodage peut être utilisée pour accéder à la clé de décodage par un nud pour tenter de visionner la version décodée du contenu de champ d'entrée.
