Abstract

L'invention concerne un procédé et un appareil pour contrôler l'accès à des données confidentielles. L'appareil selon l'invention comprend une mémoire non-volatile pour la mémorisation des données et un circuit logique pour contrôler l'accès aux données contenues dans la mémoire. Le circuit logique réalise l'accès sélectif à la mémoire en vue de déterminer si au moins une partie des données contenues dans la mémoire comprend des données confidentielles en procédant par analyse d'une propriété inhérente aux données auxquelles on a accès. Le procédé selon l'invention est caractérisé en ce qu'il comprend les étapes ci-après: définition d'une section prédéterminée de la mémoire programmable en tant que référentiel pour des données confidentielles; adressage de la section prédéterminée de la mémoire programmable; calcul d'un nombre de blocs de données dans la section prédéterminée ayant une caractéristique prédéterminée; comparaison du nombre calculé à une valeur seuil; et définition de la mémoire sous forme d'une mémoire comprenant des données confidentielles dans la section prédéterminée, si le nombre calculé présente une relation prédéterminée avec la valeur seuil.
