Binary anti-counterfeit printing method based on transposition order-change

Abstract

The invention relates to a binary anti-counterfeit printing method based on transposition order-change, which comprises the steps of generating a binary modulation signal through transposition order-change encrypting calculation and channel coding of binary anti-counterfeit information; and embedding order change of anti-counterfeit information in shape of amplitude modulation websites in a circular look-up table manner in a full page. The anti-counterfeit information can be identified from any one fragment when printing materials are identified, so that the binary anti-counterfeit printing method based on the three-dimensional encrypting anti-counterfeit information can be widely applied to the anti-counterfeit field of printing materials.

Description

Technical field: [0001] The invention relates to an anti-counterfeit printing technology, in particular to a binary anti-counterfeit printing technology with transposition and sequence encryption. The anti-counterfeiting printing technology can be used for anti-counterfeiting of various printed products. Background technique: [0002] The existing relatively common anti-counterfeiting methods are as follows: The first is laser anti-counterfeiting marks, which use laser recessive ink fluorescent ink printing technology to print product logos or special identification patterns into product anti-counterfeiting labels. And the same type of product uses the same label, because the anti-counterfeiting label is easier to forge, and the fake anti-counterfeiting label is used on the counterfeit product, causing the product to be confused, so it is difficult to effectively prevent counterfeiting. The second is the password anti-counterfeiting label. The method adopted is to compile ...

Problems solved by technology

[0002]The existing more common anti-counterfeiting methods are as follows: The first is laser anti-counterfeiting marks, which use laser hidden ink fluorescent ink printing technology to mark the product The anti-counterfeit label of the product is printed with the emblem or a special identification pattern, and the same kind of label is used for the same type of product, because the anti-counterfeit label is easier to forge, and the forged anti-counterfeit label is used on the counterfeit product, causing the product to be damaged. True and false are confused, so it is difficult to effectively prevent counterfeiting

The second is the password anti-counterfeiting label. The method adopted is to compile a set of numbers for each product, and the codes of each product are different. The numbers are printed on the labels and covered, and the numbers are stored Into the computer database that can be inquired by consumers. When consumers purchase products, they input the numbers on the logo into the computer database through telephone or network access computer for comparison and identification. The same is true, and the difference is false. The method is simple and easy to identify. It is not easy to forge, but in actual use, because the coded data is uniformly generated by the computer and printed on the label

In summary, the existing anti-counterfeiting methods have certain shortcomings, and thus cannot fundamentally prevent counterfeit products.
