Embodiment 1

[0073] Step 1. Generation of QR code and encryption of original information:

[0074] 1.1 Use the two-dimensional code generation system to generate a QR code 111 for "Hangzhou Dianzi University" (the generated QR code is a square image, and the image mode is an RGB image), and the image size is 200×200dpi;

[0075] 1.2 Use "201309111403" as the serial number to be encrypted, use the encryption program made by the programming software according to the specific algorithm encryption rules to encrypt the serial number, and obtain the encrypted serial number "#wVOKMPE";

[0076] 1.3 Take a screenshot of the encrypted serial number generated in 1.2, obtain a picture 112 containing the wording of the encrypted serial number, and save the picture as an image to be encrypted;

[0077] Step 2. Preprocessing of images to be encrypted:

[0078] 2.1 The image 112 containing the encrypted serial number is subjected to image scaling transformation to obtain an image of the same size as the...

Abstract

The invention relates to a multiple information encrypted two-dimensional code anti-counterfeiting method, which comprises the steps of generating an encrypted serial number through carrying out algorithm encryption on a digital serial number, acquiring an image containing the encrypted serial number by using a screenshot method, carrying out dimension adjustment, image graying and image scrambling processing on the encrypted serial number to acquire a secret image, inserting the secret image into a two-dimensional image by using a bit operation method by taking a two-dimensional code as a carrier so as to acquire a mixed two-dimensional code which is finally used for printing; and acquiring the encrypted serial number through extracting the secret image in the two-dimensional code and carrying out anti-scrambling processing when information verification is carried out, then acquiring a decrypted serial number by adopting a decryption algorithm, and distinguishing authenticity of information through comparing the decrypted serial number with an original serial number. The method provided by the invention realizes two-dimensional anti-counterfeiting by combining simple information algorithm encryption and a method of image conversion and image concealing. The method is easy to implement, does not influence the information capacity of the two-dimensional code, and has very good anti-counterfeiting performance.

Description

technical field [0001] The invention relates to a two-dimensional code anti-counterfeiting method for multiple information encryption, in particular to a QR two-dimensional code anti-counterfeiting method. Background technique [0002] QR two-dimensional code has been widely used as a carrier of information dissemination in today's society. While QR two-dimensional code is for people to carry out information dissemination and product promotion, due to the limitations of its own anti-counterfeiting performance, especially with the development of computer and printing reproduction technology, information reproduction has become more and more simple and convenient. . For some information with high commercial value, counterfeiting or even flooding occurs. Especially in the process of product circulation, unscrupulous manufacturers forge the packaging of genuine products, shoddy the real ones, and shoddy them, which not only damages the interests of genuine manufacturers and hi...
