A bill anti-counterfeiting method and device based on texture image features

Abstract

The invention relates to a bill anti-counterfeit method and device based on texture image characteristics. The method comprises the steps of firstly utilizing a rapid image device for selecting a certain number of areas from a paper carrier before a bill is printed, obtaining paper texture image data and area central point position information, extracting texture image characteristic information, generating bill number information, calculating an abstract information flow of variable content data, encoding all the obtained information, hiding the information in visible elements of the bills, and finally printing and outputting the complete bill makeup data. In the verification process, a paper bill file is scanned to digital image data, all hidden information is extracted, and then whether the texture image characteristic information, the bill number information and the variable content data information are consistent or not is obtained in a comparing mode so as to judge bill authenticity. The anti-counterfeit technology meets the requirements of technical exclusivity, technical reliability, identification simplicity, identification uniqueness, anti-counterfeit timeliness and the like.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting, and relates to an anti-counterfeiting method based on physical characteristics, in particular to an anti-counterfeiting method based on bill paper texture image features, and in particular to a bill anti-counterfeiting method and device for variable printing output based on image texture features. Background technique [0002] With the rapid development of the market economy, the types of commodities are also diversified to meet the needs of consumers, but counterfeit and shoddy commodities are also increasing day by day. Fake and shoddy goods not only affect the healthy development of the national economy, but also harm the interests of businesses and consumers. In order to ensure that the interests of merchants and consumers are not infringed, and to ensure the rapid development of the socialist market economy, the country invests a lot of material, financial and manpower in anti-co...
