Embodiment Construction

[0049] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings, but the embodiments of the present invention are illustrative rather than limiting.

[0050] Paper texture means that when paper is manufactured, it is made of a large number of plant fibers such as wood. On the finished paper, with a magnifying glass, it can be seen that plant fibers of different thicknesses are criss-crossed and have a pattern similar to hand grain. Some data show that these lines are formed by irregular arrangements of plant fibers with a width of 4 μm to 70 μm and a length of 0.25 mm to 50 mm during papermaking. This irregular arrangement is artificially impossible to imitate. In addition, a large number of sampling results have proved that even the same type of paper has different paper textures, and after years of use, even if the paper is discolored or polluted, it will not have a major impact on the recognition results.

Abstract

An falseproof processing method of paper money includes fetching paper veins code being used to judge said paper money uniquely at characterized region defined on paper preparing paper money, printing out paper veins code in net-screen coding mode and covering paper money drawings on it, judging realness of paper money by identifying out code value of net-screen coding in paper money drawing then comparing it with paper veins code at characterized region.

Description

technical field [0001] The invention belongs to the field of information processing, in particular to a banknote anti-counterfeiting processing method. Background technique [0002] In recent years, incidents of counterfeiting banknotes at home and abroad have frequently occurred. The proliferation of counterfeit banknotes directly affects social stability, disrupts financial order, and seriously endangers financial security. The harm caused by it has become a worldwide problem. The traditional banknote anti-counterfeiting treatment mainly adopts anti-counterfeiting methods such as special ink, watermark, embedded metal strip, engraved gravure printing, negative and positive complementary printing, etc. With the improvement of printing equipment precision and the continuous development of other technologies, the traditional method of banknote anti-counterfeiting technology is getting better and better. Losing its due effectiveness more and more, the latest anti-counterfeitin...
