Abstract

L'invention porte: sur un dispositif de vérification de la position d'un terminal mobile, économique et de haute sécurité; et sur une carte à circuit intégré (200) constituant le dispositif de vérification que l'on charge dans un terminal portable (300). La carte (200) contient une section (220) de comparaison de position comparant l'information de position GPS (L1) indiquant la position du terminal mobile (300) sur la base du signal GPS transmis par le satellite GPS, et de l'information de position (L2) indiquant la position du terminal mobile (300) transmise depuis une station de base (400) et acquise par communication radio avec la station de base (400). La section (220) de comparaison de position vérifie l'exactitude de l'information de position GPS (L1) en comparant l'information de position GPS (L1) à l'information de position (L2). Lorsque l'exactitude de l'information de position GPS position information (L1) est reconnue suite à cette vérification, la section de signature (230) signe l'objet vérifié pour en assurer la conformité.
