Abstract

La présente invention a pour objet un système de détermination de l'authenticité d'une carte à puce, etc., permettant de vérifier de façon fiable une carte à puce de contrefaçon qui est fabriquée en retirant une puce à circuit intégré d'une carte à puce authentique, sans porter atteinte au degré de liberté de conception d'une telle carte. La présente invention concerne un système de détermination de l'authenticité d'une carte à puce comprenant : une partie de lecture qui lit des informations d'image à partir d'une surface de la carte à puce et sur la base d'un motif aléatoire inhérent à la carte ; une unité d'extraction qui extrait une valeur d'élément à partir des informations d'image faisant office d'informations d'éléments ; une unité d'acquisition qui obtient des informations d'identification de la carte à puce à partir d'une puce à circuit intégré de la carte à puce ; une unité de production qui produit des informations conjointes en associant les informations d'éléments aux informations d'identification ; une unité de mémoire qui mémorise par avance les informations conjointes à titre d'informations conjointes de comparaison ; et une unité de détermination qui détermine si les informations conjointes sont identiques aux informations conjointes de comparaison en comparant les informations conjointes obtenues à partir de la carte à puce et produites aux informations conjointes de comparaison mémorisées dans l'unité de mémoire.
