Abstract

L'invention concerne un code d'identification de type puzzle à image, ainsi qu'un système et un procédé pour sécuriser des informations. Dans ce système et selon ce procédé pour sécuriser une image au moyen de ce code, une image originale (10) contenant une photographie, un élément graphique, un caractère, un nombre, une empreinte digitale ou un iris est divisée en éléments d'image et ces éléments d'image sont réorganisés de façon à produire une image de code d'identification (20), l'image originale (10) étant restaurée à partir de l'image de code d'identification (20) si nécessaire. Ce système et ce procédé permettent ainsi d'empêcher efficacement la divulgation d'informations au moyen de l'image de code d'identification (20), le processus d'identification et de validation de l'identité pouvant être exécuté tout en préservant la sécurité en termes de confidentialité des informations personnelles ou des informations physiques personnelles, telles qu'une empreinte digitale ou l'iris de l'oeil.
