Abstract

L'invention concerne un code QR de sécurité utilisant un hologramme. Un procédé d'enregistrement du code QR d'hologramme selon un mode de réalisation de la présente invention consiste à générer un code QR d'hologramme en tant que motif de frange holographique et à enregistrer le motif de frange holographique généré sur un support d'hologramme, le code QR d'hologramme comprenant un premier code QR contenant des informations chiffrées et un second code QR contenant une clé permettant de décoder les informations chiffrées. En conséquence, le code QR est enregistré sous la forme d'un hologramme sur un support d'enregistrement de l'hologramme et affiché/balayé, et ne peut donc pas être facilement copié comme un code QR 2D classique.
