Abstract

L'invention concerne, dans divers modes de réalisation, un procédé et un système informatisés de désignation et / ou de protection d’informations confidentielles dans un document original, le procédé comportant l'étape consistant à recevoir un fichier contenant le document original via une interface de réseau informatique. Le document original contient des informations confidentielles et peut être stocké dans une ou plusieurs bases de données structurées configurées dans une ou plusieurs mémoires. Une interface d’utilisateur est placée entre le processeur et l’utilisateur associé au document original. L’utilisateur identifie au moins une partie des informations considérées comme confidentielles par l’intermédiaire de l’interface d’utilisateur. Le processeur peut identifier chaque occurrence des informations confidentielles contenues dans le document original, et peut générer sélectivement un ou plusieurs fichiers censurés ou confidentiels dans lesquels chaque occurrence des informations confidentielles présentes dans le document original est masquée ou censurée. L’utilisateur peut choisir de ne censurer aucune des informations confidentielles. Les fichiers censurés peuvent être stockés dans une ou plusieurs bases de données structurées de telle sorte que les fichiers censurés soient accessibles en vue d’une récupération sélective par l’utilisateur originel et / ou par un utilisateur différent.
