Abstract

La présente invention concerne un marquage anti-contrefaçon à texture aléatoire, comprenant : un support, multiples particules texturées sont aléatoirement distribuées sur la surface d'appui du support, la surface sans contact de chaque particule de texture comprend au moins deux parties de couleur visuelle, chacune desquelles rendant des couleurs visuelles respectives, de telle sorte qu'il existe au moins un angle d'inclinaison auquel une couleur visuelle intégrale formée par les multiples particules texturées est observée, et qu'il existe une différence de couleur visuelle distinguable par le regard entre la couleur visuelle intégrale et une autre couleur visuelle intégrale formée par les multiples particules texturées observées selon une direction perpendiculaire à la surface d'appui. La présente invention permet de reconnaître la caractéristique de reconnaissance spéciale de particules texturées dans le marquage anti-contrefaçon à texture aléatoire sans utiliser d'outils auxiliaires, ce qui améliore considérablement la participation publique. La présente invention concerne également un système anti-contrefaçon utilisant le marquage anti-contrefaçon à texture aléatoire, des particules texturées utilisées dans le marquage anti-contrefaçon à texture aléatoire et leur procédé d'utilisation, permettant d'obtenir des effets techniques bénéfiques identiques.
