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

[0010] In the process of loading anti-counterfeiting information figure 1 Among them, the original anti-counterfeiting information (image, text, trademark is digitally processed 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 to a 16-bit binary information to generate high-level anti-counterfeiting information. A 16-bit binary anti-counterfeiting information table whose 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-digit binary encryption parameter is denoted as C, the encryption parameter C is an integer of 1≦C≦255, the operator@ k Four types of +, -, ×, ÷ are used, and the two-digit binary operator control variable is recorded as k, and the operator control variable k is an integer of 0≦k≦3. When the operator contr...

Abstract

The invention relates to a binary anti-fake printing method by two-dimensional encryption. According to the method, binary anti-fake information can be converted into a binary modulation signal by Ni@kC encryption operation and channel encoding, and the anti-fake information is embedded in the full page in a circulating look-up table modulation manner in orderly change of shapes of amplitude modulation websites, so that the anti-fake information can be identified from any one fragment when a printed matter is identified. The method can be widely applied to the field of forgery prevention of printed matters.

Description

Technical field: [0001] The invention relates to an anti-counterfeiting printing technology, in particular to a two-dimensional encrypted binary anti-counterfeiting printing technology, which 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 a set of numbers for each product, and the codes of...
