Abstract
(EN)
A clone-proof QR code (1) and an anti-counterfeiting QR code authentication method for same. The QR code (1) is a QR code in which a pixel dot matrix represented by a binary code is provided on a two-dimensional plane, and comprises: a data area (10), which stores information; and a position detection pattern (20), which is provided around the data area (10), wherein in the data area (10), the pixel dot matrix undergoes halftone processing to form a multi-level gray scale. Regarding the present QR code (1), the clone-proof ability of the QR code can be improved while maintaining the versatility of the QR code.
(FR)
L'invention concerne un code QR anti-clone (1) et un procédé d'authentification de code QR anti-contrefaçon pour ledit code. Le code QR (1) selon l'invention est un code QR dans lequel une matrice de points de pixel représentée par un code binaire est disposée sur un plan bidimensionnel, et comprend : une zone de données (10) destinée à stocker des informations; et un motif de détection de position (20) formé autour de la zone de données (10), la matrice de points de pixel subissant, dans la zone de données (10), un traitement en demi-teinte pour former une échelle de gris à plusieurs niveaux. Le code QR (1) selon l'invention présente une capacité anti-clonage améliorée tout en conservant sa polyvalence.
