Problems solved by technology

However, the QR code has no anti-copy function, and the attacker can tamper with the data information of the QR code, which is often the bank account information of individuals and businesses. Once tampered with, economic losses will occur, and the tampered QR code It is difficult for the human eye to distinguish the authenticity from the false

Embodiment Construction

[0036] The embodiments of the present invention will be further described below with reference to the accompanying drawings, but the described embodiments of the present invention are illustrative rather than limiting.

[0037] A method for beautifying QR code authentication with secrets, specifically comprising the following steps:

[0038] Step 1: Generate a reference QR code

[0039] Step 2: Construct the forward and reverse basis matrix

[0040] Step 3: Generate Transition QR Code

[0041] Step 4: Module attribute judgment

[0042] Step 5: Module Brightness Adjustment

[0043] Step 6: Embed Watermark

[0044] The generation of the reference QR code described in step 1 is specifically implemented as follows:

[0045] 1-1. For the input background image I of size n×n, grayscale it and obtain the grayscale image I g ;

[0046] 1-2. According to the module length of the QR code, the grayscale image I g Divide into blocks according to the module structure of the origina...

Abstract

The invention discloses a secret-containing beautification QR code authentication method. The method comprises the following generation steps of binarizing an input background image to generate a reference QR code; according to an RS code, establishing a forward basis matrix, and generating a reverse basis matrix through a Gaussian Jordan elimination method; performing black and white turnover ona module with a high QR code priority by utilizing the forward and reverse basis matrixes to obtain a transient QR code image; judging a module attribute for brightness adjustment of a small check inthe module; adjusting module brightness and generating a beautification QR code image in combination with other two channels; and combining the beautification QR code with a digital watermark anti-counterfeit technology to generate a secret-containing beautification QR code. By adopting the beautification QR code, a tag carries a large amount of product information and the attractiveness of a package is improved; a digital watermark is added based on the beautification QR code, so that the anti-counterfeit performance of the QR code is enhanced; and the QR code is combined with the digital watermark anti-counterfeit technology, so that the anti-counterfeit performance is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of QR codes and provides a method for authenticating QR codes with secrets and beautification. A method including fusing background images and QR codes and embedding digital watermarks to achieve authenticity authentication of QR codes. Background technique [0002] With the advent of the Internet era and the popularity of smart phones, QR codes can be seen everywhere in daily life. Currently, as one of the entrances to the mobile Internet, QR codes have become the most common The QR code used. In mobile payment, QR code plays an important role as the carrier of secret information, mainly due to the advantages of small size, convenient portability and large data storage capacity of QR code. However, the QR code has no anti-copy function, and the attacker can tamper with the data information of the QR code, which is often the bank account information of individuals and businesses. Once tampered with, econom...
