“…Researchers have investigated two primary approaches to make markers less obtrusive: making visible tags more aesthetic [2,11,23,25], embedding tags inside the object [6,20,34], or having tags that are invisible to the human eye on the surface of the object [5,21].…”

“…To make codes more aesthetic, researchers have modified traditional QR codes (halftoned) to look more like an aesthetic image (e.g., a photo) while still preserving its detectability [25]. ReacTIVision [2] creates fiducial markers that look like amoeba to create an organic look.…”

“…As QR codes become more and more common in practice, many efforts have been made to improve it to support more application scenarios, such as QR Code beautification [12,13,14,15,16,17,18,19,20], increasing the storage capacity of the QR code [21,8] and so on. However, the inability to distinguish physical copying limits its applications.…”

The popular use of high quality printing and scanning equipment makes it easier to counterfeit important printed matter, such as important document, anti-counterfeit label on merchandise, packaging, etc. Previously, methods such as textured image, two-level quick response (2LQR) code, fractional-order spatial steganography, etc., have been used for printed matter authentication. In this paper, a simplified model is proposed to analyze the variation of the correlation of textured-patterns (hereinafter called patterns) after the print-and-scan (P&S) process, which gives accurate mathematical descriptions of the information loss during P&S processes. Based on previous theoretical results, we propose the two-stage textured-patterns embedded QR (2SQR) codes for printed matter authentication, which are based on 2LQR codes and sensitive to P&S process. In the generation process, the stage two (S2) patterns are introduced, which are the corresponding P&S version of the textures in the 2LQR codes, i.e., stage one (S1) patterns. Then part of the S1 patterns in 2LQR codes are replaced with the corresponding S2 patterns, resulting in the 2SQR codes. In the authentication process, the 2SQR indicator is used to eliminates the need for the original image, which eliminates the storage and retrieval process of the original images. Experiments show that, compared with the 2LQR codes, the 2SQR codes significantly improve the performance in distinguishing the authentic codes and their copied version.

“…Yatagawa and Yamaguchi [33] present a method for the appearance editing for images. The paper by Hua and Wang [34] presents an image completion method and the last paper related to image processing is by Qiao et al [35]; they describe a technique to generate QR codes that are visually similar to an input image.…”
