Anti-fake label composed of ink dots and fluorescent substance and anti-fake label discrimination method

Abstract

The invention provides an anti-fake label composed of ink dots and fluorescent substance. The anti-fake label comprises a graph formed by the multiple ink dots and one or two kind(s) of a fluorescent area or fluorescent powder or a plurality of fluorescent dots. An anti-fake label discrimination method comprises the steps that a camera device is used for taking a picture of the dot-matrix graph, so that a dot-matrix image of the anti-fake label is obtained; the dot-matrix image is discriminated, and when the discrimination result is true, a fluorescent substance recognition device is activated to take a picture of the surface of the anti-fake label, so that a fluorescent substance is obtained; the fluorescent substance image is discriminated, and a corresponding information file is output when the discrimination result is true. According to the anti-fake label composed of the ink dots and the fluorescent substance and the anti-fake label discrimination method, the fluorescent substance recognition device is activated according to the discrimination result of the dot-matrix graph to obtain the fluorescent substance image in the anti-fake label, corresponding information is output according to the discrimination result of the fluorescent substance image, as a result, whether the object corresponding to the current anti-fake label is true or not can be known, and the anti-fake effect can be further improved.

Description

technical field [0001] The invention relates to an anti-counterfeit mark, in particular to an anti-counterfeit mark composed of ink dots and fluorescent substances and a method for distinguishing it. Background technique [0002] At present, when identifying the authenticity of the current article, the authenticity of the current article is judged by means of identifying the dot matrix pattern. However, the existing authenticity discrimination method is relatively simple, and once the algorithm of the dot matrix pattern is cracked, the anti-counterfeiting function cannot be achieved. Contents of the invention [0003] Aiming at the deficiencies in the above problems, the present invention provides an ink dot and fluorescent method that can further improve the anti-counterfeiting effect compared with the existing method of judging the authenticity of the current article only through the identification result of the dot matrix image. The anti-counterfeiting mark of material...
