Abstract

La présente invention concerne un procédé de recherche d'informations dans un corpus chiffré stocké sur un serveur, à partir d'une requête numérique calculée sur un équipement client, contenant une séquence de termes, comportant les étapes suivantes : - Chiffrement de ladite requête (20) sur un équipement informatique client (1) et transmission à un serveur (1) de gestion de base de données (3) - Calcul homomorphe sur le serveur de la réponse chiffrée (41) à la requête chiffrée (40) enregistrée sur le serveur (2) Caractérisé en ce qu'il comporte une étape additionnelle de requêtage exécutée sur l'équipement client (1), d'agrégation desdits identifiants des données contenues dans ladite réponse chiffrée (50) et dans l'index df_A (13) enregistré sur l'équipement client (1) - la présentation du résultat sous une forme ordonnée des documents en application du traitement de l'étape précédente. L'invention concerne aussi un procédé de préparation d'une base requêtable et un procédé de recherche d'informations dans un corpus chiffré.
