Embodiment Construction

[0048] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, but the embodiments of the present invention are illustrative rather than restrictive.

[0049] Paper grain refers to the processing of a large number of plant fibers such as wood when paper is manufactured. On the finished paper, you can see that plant fibers of different thicknesses criss-cross and have similar patterns such as hand patterns. Some data indicate that these lines are formed in an irregular arrangement of plant fibers with a width of 4μm to 70μm and a length of 0.25mm to 50mm during papermaking. This irregular arrangement is artificially impossible to imitate. In addition, the results of a large number of samples have proved that even the same type of paper has different paper textures. Moreover, after years of use, even if the paper is discolored or contaminated, 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 an anti-counterfeiting processing method for banknotes. Background technique [0002] In recent years, incidents of counterfeiting paper money have occurred frequently at home and abroad. The proliferation of counterfeit money has directly affected social stability, disrupted the financial order, and seriously endangered financial security. The harm it caused has become a worldwide problem. Traditional banknote anti-counterfeiting processing mainly uses special inks, watermarks, embedded metal strips, engraving gravure printing, Yin and Yang complementary printing and other anti-counterfeiting methods. With the improvement of printing equipment accuracy and the continuous development of other technologies, traditional methods of banknote anti-counterfeiting technology It has lost more and more performance. Now the latest international banknote anti-counterfeiting methods mainly i...
