An image two-dimensional code based on information hiding and its generation method and system

Abstract

The invention relates to an image two-dimension code based on information hiding. The two-dimension code comprises a positioning module and a data module. The data module is an image which is used to embed information data into a host image. The information data is a matrix-type binary system string of original data formed by coding and an error correcting code. The positioning module is used for limiting a boundary of the data module. By using the image two-dimension code based on information hiding, data information is embedded into the host image, which means that the information data is hidden in the image. On an aspect of an aesthetic property, a main body appearance of the image two-dimension code is formed by the image and is more beautiful than that of a traditional square and monotonous black and white geometric image. Simultaneously, the image is used to carry the data so that two-dimension code information can be prevented from being forged and tampered. Because of a safe mode design, a current popular two-dimension code attack mode is avoided and safety is increased.

Description

technical field [0001] The invention relates to a two-dimensional code and a generation method thereof, in particular to an image two-dimensional code based on information hiding and a generation method and system. Background technique [0002] At present, with the continuous development of smart devices and wireless networks, two-dimensional codes with obvious characteristics of the information age are widely used in logistics, business information exchange, commercial advertising, anti-counterfeiting, electronic tickets and other fields. The two-dimensional code in the print advertisement enables consumers to use mobile devices to obtain a large amount of commodity information conveniently and quickly; at the same time, due to the appearance of the two-dimensional code itself with IT features, the two-dimensional code itself has almost become synonymous with innovation and high technology. . However, with the wide application of QR codes, its shortcomings in security and ...

AI Technical Summary

Problems solved by technology

The square and monotonous appearance of the two-dimensional code itself prevents it from being perfectly integrated with the entire advertising design, so how to embed the two-dimensional code in the print advertisement has become an important design point for graphic designers

But the problem still exists. In the advertisement design, the shape of the logo should be simple, concise, and have a strong visual effect, which can leave a deep impression on consumers.

In the case of using the QR code embedded in the logo as a whole as the logo, the logo only exists in a small area in the middle, so the design is obviously not the simplest and most concise

Moreover, the black and white grid of the QR code itself cannot be recognized by human eyes at all.

In response to this problem, relevant companies have made many meaningful attempts. These attempts have tried to solve the problem of the appearance of the QR code, but there are fatal flaws in all of them.
