Embodiment Construction
[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0039] The overall flow chart of the present invention is as figure 1 shown. The two-dimensional code anti-counterfeiting method based on near-infrared spectrum analysis of the present invention includes a two-dimensional code generation process and a two-dimensional code reading process.
[0040] The two-dimensional code generation process is as follows figure 2 As shown, it specifically includes the following steps:
[0041] Step a1: selecting an ink containing a specific concentration of hydrogen group components for proofing to obtain a corresponding sample, and collecting near-infrared spectral information of the sample by a near-infrared spectrometer.
[0042] Step a2: Perform principal component analysis on the near-infrared spectral information collected in step a1 to obtain corresponding principal component vectors. Wherein, perf...
