Embodiment Construction

[0041] In order to better understand the technical solutions and features of the present invention, the implementation of the present invention will be further described below in conjunction with the accompanying drawings in the specification.

[0042] This embodiment provides an anti-counterfeiting method for a combined two-dimensional code that can prevent copying, which is characterized in that it includes the following steps:

[0043] Step S1: Make a QR code, the specific method is as follows:

[0044] S11: Select the ink containing hydrogen group components to make a sample to obtain the corresponding sample, and collect the near-infrared spectrum information of the sample color through a near-infrared spectrometer; in this embodiment, the spectral wavelength range of the near-infrared spectrometer is 800-1400nm Corresponding wave number 12500~7142.9cm -1 )between;

[0045] S12: Perform principal component analysis on the collected near-infrared spectrum to obtain corre...

Abstract

The invention relates to a combined two-dimensional code anti-counterfeiting method capable of preventing copy. Printing ink containing hydrogen radicals and common printing ink are used for printing different parts of a two-dimensional code, and a part of near infrared spectrum is printed by the printing ink containing the hydrogen radicals to achieve the anti-counterfeiting purpose of the two-dimensional code. The method comprises the steps of manufacturing the two-dimensional code, and recognizing and comparing the two-dimensional code. The method solves the problem that the manufacturing and printing technologies of the two-dimensional code are complicated in an invisible two-dimensional code anti-counterfeiting method; in addition, a near infrared spectrum analysis method is introduced to analyze the special printing ink containing the hydrogen radicals; even the printing ink has the same color, near infrared spectra corresponding to the printing ink are different to a greater extent, so that the copy prevention effect can be exerted; and the counterfeiting prevention of the two-dimensional code is realized accordingly.

Description

technical field [0001] The invention belongs to the technical field of two-dimensional codes, and in particular relates to an anti-counterfeiting method for a combined two-dimensional code capable of preventing duplication. Background technique [0002] The two-dimensional code uses a specific geometric figure to record data symbol information on the two-dimensionally distributed graph according to certain rules, and can store the information of the anti-counterfeiting object in an implicit way for anti-counterfeiting. The advantage of introducing two-dimensional code technology is that it can be extremely The earth stores the personalized information of the anti-counterfeiting object, including graphic text, sound and so on. At the same time, the generation and production cost of the two-dimensional code is relatively low, so it has been applied in many fields. At present, anti-counterfeiting methods based on QR codes mainly include the following methods: [0003] 1. Encr...
