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 e

Embodiment Construction

[0014] 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 eight-bit binary encryption parameter is denoted as C, the encryption parameter C is a positive integer of 0≤C≤256, the two-digit binary operator control variable is denoted as k, and the operator control variable k is 0≤ A positive integer with k≤3, operator Using +, -, ×, ÷ four operators, operator control variable k = 0 They are respectively defined...

Abstract

The invention provides a single-parameter and double-variable-sequence encryption type binary anti-counterfeit printing method; according to the method, through encryption operation and channel coding, binary anti-counterfeit information can be generated into a binary modulating signal; and the orderly change of the anti-counterfeit information in the form of an amplitude modulation dot is embedded into the whole page through a circulating table lookup method; the anti-counterfeit information can be identified from any fragment during identifying a printing material; and the single-parameter and double-variable-sequence encryption type binary anti-counterfeit printing method provided by the invention can be widely applied to the anti-counterfeit field of printing materials.

Description

Technical field: [0001] The invention relates to an anti-counterfeiting printing technology, in particular to a single-parameter double-ordered encrypted binary anti-counterfeiting printing technology. 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 comp...
