Abstract

The invention relates to a multi-parameter double incremental 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 multi-parameter double incremental encrypted binary anti-counterfeiting printing method can be widely applied to the field of anti-counterfeiting of printed matters.

Description

Double the increasing progressively of multiparameter encrypted the scale-of-two antiforging printing method
affiliated technical field:
The present invention relates to a kind of anti-counterfeiting printing technology, particularly double the increasing progressively of a kind of multiparameter encrypted 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 , encrypt

With
Figure 2012104042926100001DEST_PATH_IMAGE011
, wherein
Figure 677842DEST_PATH_IMAGE010
Be defined as the numeral 0,
Figure 94917DEST_PATH_IMAGE011
Be defined as numeral 1, utilize the binary add tight defense fake information of 16 group generated through chnnel coding, generation has 16 one group of binary modulated signals of error detecting and error correcting function, original continuous is changed the line map, and image signal is processed (RIP) through rasterizing and hybrid screening is exported halftoning hybrid screening picture signal, comprising amplitude and FM screened image signal, 16 one group of binary modulated signals that utilize to generate adopt the shapes of amplitude in circulation look-up table modulation system modulation hybrid screening picture signals, the shape that makes amplitude according to With Regular changing, make adjacent 16 amplitudes in the hybrid screening picture signal carry 16 binary add tight defense fake informations by the change of shape, thereby be created on the hybrid screening picture signal that embeds anti-counterfeiting information in the full page site, realize anti-counterfeit printing.
