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.

Embodiment Construction

[0013] In the process of loading anti-counterfeiting information figure 1 Among them, the original anti-counterfeiting information (image, text, trademark) is digitized to generate an 8-bit binary anti-counterfeiting information table, and the 8-bit binary information in the binary anti-counterfeiting information table is expanded into a 16-bit binary information to generate A 16-bit binary anti-counterfeiting information table whose upper 8 bits are all 0, and the i-th group of 16-bit binary information in the 16-bit binary anti-counterfeiting information table is denoted as N i , i is a positive integer greater than 0, the binary control variable is denoted as j and k, the binary step control variable is denoted as h, the control variable k is a positive integer of 0≦k≦3, and the control variable j is 0≦j≦256 Positive integer, the step size control variable h is a positive integer of 0≦h≦256, the eight-digit binary encryption parameter is denoted as C, and the encryption pa...

Abstract

The invention relates to a dynamic variable-parameter double encrypted binary anti-counterfeiting printing method which comprises the following steps: generating binary anti-counterfeiting information into a binary modulation signal through encryption algorithm and channel coding and embedding the anti-counterfeiting information into a whole page through the orderly change of the shape of an amplitude modulation dot in a circular table look-up method modulation manner. When printed matters are identified, the anti-counterfeiting information can be identified from any one fragment; and the dynamic variable-parameter double encrypted binary anti-counterfeiting printing method can be widely applied to the printed matter anti-counterfeiting field.

Description

[0001] Technical field: [0002] The invention relates to an anti-counterfeiting printing technology, in particular to a dynamic variable parameter double-encrypted binary anti-counterfeiting printing technology, which can be used for anti-counterfeiting of various printed products. [0003] Background technique: [0004] 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 a set of number...
