Abstract

L'invention concerne un procédé et un système permettant le cryptage et le décryptage de différentes sections d'un document fournissant différents niveaux d'accès dans une technique employant différentes clés. Les documents peuvent être cryptés à un niveau de section de document (« section » étant ici utilisé dans son sens général), avec utilisation de différents jeux de clés de cryptage pour chaque section. Un utilisateur A à niveau d'accès 1 peut avoir accès uniquement à la section codée sous accès niveau 1, plus des sections non codées. Un exemple d'application de cette technique concerne les hôpitaux. Des enregistrements pour patients peuvent être segmentés chacun en parties cryptées séparément, donnant accès à des infirmières uniquement pour une matière appropriée, tout en fournissant un plus large accès aux médecins. L'infirmière sera pourvue de sa clé privée pour avoir accès aux parties du document que les infirmières ont droit de consulter. On peut également prévoir un niveau dont l'accès est réservé uniquement au médecin de premier recours ou au prestateur de soins de santé.
