Abstract

The invention provides a single-variable, double-parameter-displacement and increasing encryption type binary anti-counterfeit printing method; according to the method, through [+++] encryption operation and channel coding, binary anti-counterfeit information can generate 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-variable, double-parameter-displacement and increasing encryption type binary anti-counterfeit printing method provided by the invention can be widely applied to the anti-counterfeit field of the printing materials.

Description

The double parameter displacement of single argument increases progressively encrypts the scale-of-two antiforging printing method
affiliated technical field:
The present invention relates to a kind of anti-counterfeiting printing technology, particularly the double parameter displacement of a kind of single argument increases progressively and encrypts the scale-of-two anti-counterfeiting printing technology, and what this anti-counterfeiting printing technology can be for various printed matters is false proof.
background technology:
Existing comparatively common method for anti-counterfeit has following several: the first is laser anti-false sign, the symbol of product or special identification icon are printed to the anti-fake label of product by the recessive printing ink daylight fluorescence ink of laser printing technology, and the same class product is used the same labeling, because anti-fake label is easier to forge, and the anti-fake label of forging is used on fake products, cause the true and false of product to obscure, therefore be difficult to effectively false proof.The second is the cipher counterfeit-proof labeling, its method adopted is that every product is compiled one group of number, the coding of every product is not identical, this number is printed on labeling and hides, this number is deposited in the Computer Database that can inquire about for the consumer simultaneously, when the consumer buys product, number on sign is compared to identification by phone or networking computer input Computer Database, identical being very, difference is vacation, method is simple, identification easily, be difficult for forging, but in actual the use, because coded data is the rear labeling of printing of the unified generation of computing machine.The true and false coded data of representative products may be faked by illegal copies, and simultaneously, the coding on the product of the also recyclable not inquiry of encoding is made mark and is attached on the false pain product, and antifalse effect is difficult to guarantee.The third is texture anti-fake, false proof with the textural characteristics on its labeling, although more difficult forgery, but due to a serial number of bidding subsides, and be plain code, every piece of labeling can be inquired about repeatedly, in the necessary textural characteristics grid that the fake producer can be by warehouseman or shop-assistant be reflected during by the sequence number on labeling and inquiry have or not phenomenon to plagiarize after by this feature, forge in batches.In sum, all there is certain shortcoming in existing method for anti-counterfeit, thereby can not be from prevent fake products at all.
summary of the invention:
The shortcoming existed in order to overcome existing various printed matter anti-counterfeiting printing technology, the deficiency that the present invention is directed to existing printed matter anti-counterfeiting printing technology existence is improved prior art, a kind of encryption counterfeit printing technology of shape of scale-of-two coded signal modulation printed matter amplitude has been proposed, this anti-counterfeiting printing technology is embedded in anti-counterfeiting information in full page by the change of the shape of amplitude, can when identifying, printed matter identify anti-counterfeiting information from any one fragment, therefore there is very strong crush resistance, can fundamentally stop to adopt and take a picture, scanning waits the bootlegging behavior.
The technical solution adopted for the present invention to solve the technical problems is: the amplitude in the flexographic printing hybrid screening and frequency-modulation halftone dot are separately processed, utilize image information, Word message, the anti-counterfeiting information such as trademark information generate the binary system anti-counterfeiting information table of 8 group, for preventing from ciphering process producing information spillover, 8 one group of binary messages in binary system anti-counterfeiting information table are expanded to 16 one group of binary messages, the generation most-significant byte is 0 16 one group binary system anti-counterfeiting information table entirely, 16 binary messages of i in 16 one group binary system anti-counterfeiting information table group are denoted as to N i, i is greater than 0 positive integer, and the eight-digit binary number encryption parameter is denoted as C, the positive integer that encryption parameter C is 0<=C<=256, two binary operator control variables are denoted as k, the positive integer that operator control variables k is 0<=k<=3, operator
