The QR (Quick Response) code is a two-dimensional barcode, which was designed for storage information and high speed reading applications. Being cheap to produce and fast to read, it becomes actually a popular solution for product labeling.
Ones try to make QR code a solution against counterfeiting. We present a novel technique that permits to create a secure printed QR code which is robust
against Scan & Reprint attack. The code, named as W-QR code, is constructed by replacing the background of the standard one by a specific textured pattern which does not affect the normal reading of the
encoded message.
Scan & Reprint attacks lead to the degradation of the texture and change its statistical characteristics which can be detected thanks to a statistical test.
