Description
Technical Field
The invention relates to printing equipment, in particular to unique texture anti-counterfeiting two-dimensional code printing equipment for a packaging material.
Background
At present, various counterfeit commodities such as cigarettes, wine, medicines, foods and the like as well as certificates, tickets, entrance tickets, documents, tax invoices, bank notes and the like are counterfeited endlessly and frequently in society, which not only damages the legal rights of consumers, but also possibly harms the health and the life of the consumers; but also disturbs market order, damages the commercial reputation and interests of manufacturers, and more seriously jeopardizes the national financial safety and financial order.
The two-dimensional code technology has the characteristics of large storage capacity, high confidentiality, high traceability, strong damage resistance, high redundancy, low cost and the like, and the characteristics are particularly suitable for anti-counterfeiting of commodities and bills. However, the information of the two-dimensional code has optical visibility, that is, the anti-counterfeiting information can be easily obtained by optical methods such as scanning, photographing, copying and the like, which is a weak point. The weakness also opens the door for the mass copying of the two-dimensional code anti-counterfeiting label, and brings much trouble to the management and monitoring of the anti-counterfeiting label.
In order to solve the problem that the two-dimensional code is easy to copy, in a Chinese patent application with the application number of CN201510000535.3, the invention discloses a commodity two-dimensional code anti-counterfeiting method based on a background textural feature extraction algorithm and provided with a scratch covering layer, wherein the content of the method is that a two-dimensional code printing area and a textural feature extraction area are selected on a commodity outer package, and the textural feature extraction area is larger than and comprises the two-dimensional code printing area; then, extracting texture features of the texture feature extraction area except the two-dimensional code printing area, and encoding the extracted texture feature parameters; combining the texture characteristic parameter code with the related information of the commodity to form two-dimensional code information; and generating a two-dimensional code from the two-dimensional code information, printing the two-dimensional code on a two-dimensional code printing area, and finally covering a covering layer on the two-dimensional code printing area. The texture feature extraction algorithm may be a fractional calculus texture feature extraction algorithm. Also provides a commodity two-dimensional code anti-counterfeiting system based on the anti-counterfeiting method.
The Chinese invention patent application mainly sets the lightproof scratch-off covering layer which covers the two-dimensional code, and the anti-counterfeiting verification of the commodity is carried out after the product is scratched off by the consumer, so that the optical visibility of the current popular two-dimensional code technology is avoided, namely, the commodity with the scratch-off covering layer is invalid for the consumer, the consumer can not purchase the commodity, and the anti-counterfeiting performance and the commodity counterfeiting cost of the system are greatly enhanced by adding the covering layer on the two-dimensional code: for a counterfeiter, in order to obtain a two-dimensional code image, at least one removable cover layer of a commodity must be removed, but if the removable cover layer of the commodity is removed completely, the commodity is determined to be sold, so that a consumer cannot accept the commodity, the commodity cannot be sold, and if the counterfeiter counterfeits a large number of commodities according to one or more two-dimensional codes, data is sent to a manufacturer database after the two-dimensional code data is detected at a detection end, and only one corresponding record is in the database, the large number of copied counterfeited commodities cannot be qualified after being detected, so that the counterfeiter cannot verify that the large number of counterfeited commodities are counterfeit goods through detection.
The significance of scraping the covering layer is not great, and the key point is to solve the problem of uniqueness of the two-dimensional code.
Therefore, the Chinese patent application also discloses a method for superimposing textures on two-dimensional codes, wherein the texture characteristics specifically refer to the characteristics of lines, colors, color changes, printed patterns and the like on the outer package of the commodity; or, the texture can also refer to the texture and the grain characteristic of the internal structure of the outer packaging material of the commodity. For the same commodity, the outer package design of each specific commodity is the same, but because the grain difference caused by the slight difference of the outer package in the manufacturing process and the pattern printed on the outer package in the printing process are not completely consistent, and the difference generated by the fact that the grain of the inner structure of the outer package material (generally paper or plastic material) is not completely identical, the factors cause the color and color change, the difference of the pattern, the surface grain and the grain of the inner structure in a certain area on the outer package of the commodity to be different and difficult to avoid.
However, as described in the above-mentioned chinese patent application, there may be very weak differences in the texture feature extraction area, such as lines, colors, patterns, etc., and the image processing is difficult to distinguish, and for texture feature extraction, the feature parameters that may be extracted are substantially the same, which may not guarantee the uniqueness of the two-dimensional code, in order to ensure that the feature parameters in the texture feature extraction area of each commodity have obvious differences, the chinese patent application artificially adds some randomly generated textures in the feature extraction area, such textures may be stripes, patterns, dot matrixes, characters, numbers, etc., or randomly generated textures, and these textures may be randomly generated and printed on the texture feature extraction area after the texture feature extraction area is determined, or may randomly generate textures in advance and calculate their texture feature parameters, and print the textures on the texture feature extraction area while printing the two-dimensional code.
However, the above mentioned goods have basically the same defects based on the texture and pattern of the goods, and the artificially added stripes, patterns, dot matrixes, characters, numbers, etc. or randomly generated textures rely on computer programs, which look random, but can be copied only by cracking the algorithm, so that it is difficult to achieve the purpose of unique anti-counterfeit identification of goods.
