Two-dimensional code anti-counterfeiting method based on near infrared spectrum analysis

Abstract

The invention relates to a two-dimensional code anti-counterfeiting method based on near infrared spectrum analysis, which comprises a two-dimensional code generating process and a two-dimensional code reading process. The two-dimensional code generating process comprises the steps of selecting a certain printing ink to carry out sample making, acquiring a corresponding sample, and collecting near infrared spectrum information of the sample; carrying out principal component analysis on the near infrared spectrum information to acquire a corresponding principal component vector; encrypting the principal component vector to generate an encrypted text; finally storing the content comprising the encrypted text acting as additional information and two-dimensional code original information acting as the two-dimensional code, and generating a product two-dimensional code. The two-dimensional code reading process comprises the steps of collecting the near infrared spectrum information of the product two-dimensional code; carrying out principal component analysis on the near infrared spectrum information to acquire the corresponding principal component vector; comparing the principal component vector of the near infrared spectrum information with the additional information stored in the product two-dimensional code, if the principal component vector is matched with the additional information, authenticating the product two-dimensional code to be true, if not, authenticating the product two-dimensional code to be fake. The method provided by the invention is not only good in anti-counterfeiting effect, but also convenient to manufacture and low in production cost.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting two-dimensional codes, in particular to an anti-counterfeiting method for two-dimensional codes based on near-infrared spectrum analysis. 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 Dadi 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...
