Abstract
The invention relates to a binary anti-fake printing method by multiparameter left-shift deflection stepped ascending encryption. According to the method, binary anti-fake information can be converted into a binary modulation signal by 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:
The present invention relates to a kind of anti-counterfeiting printing technology, particularly the displacement that moves to left of a kind of multiparameter strides increment encryption scale-of-two anti-counterfeiting printing technology, and this anti-counterfeiting printing technology may be used for the false proof of various printed matter.
Background technology:
Existing comparatively common method for anti-counterfeit has following several: the first is laser anti-false sign, by laser recessive ink daylight fluorescence ink printing technology, the symbol of product or special identification icon are printed to the anti-fake label of product, and same class product uses same labeling, because anti-fake label is easier to forge, and the anti-fake label forged is used on fake products, cause the true and false of product to obscure, be therefore difficult to effectively false proof.The second is cipher counterfeit-proof labeling, its method adopted is that every part product compiles one group of number, the coding of every part product is not identical, this number is printed on labeling and also hides, simultaneously by this number stored in can for consumer query Computer Database in, when consumer buys product, number in mark is compared identification by phone or networking computer input Computer Database, identical be true, difference is vacation, method is simple, identify easily, not easily forge, but in actual use, rear printing labeling is generated because coded data is that computing machine is unified.The true and false coded data of representative products may be illegally duplicated fraud, and meanwhile, the coding of coding also on the recyclable product do not inquired about is made mark and be attached on false pain product, and antifalse effect is difficult to ensure.The third is texture anti-fake, false proof with the textural characteristics on its labeling, although more difficult forgery, but due to the serial number of only bidding subsides, and be plain code, every piece of labeling can be inquired about repeatedly, and fake producer forges by this feature batch after the presence or absence phenomenon in the necessary textural characteristics reflected when the sequence number on labeling and inquiry and grid being plagiarized by warehouseman or shop-assistant.In sum, all there is certain shortcoming in existing method for anti-counterfeit, thus can not from preventing fake products at all.
Summary of the invention:
In order to overcome the shortcoming that existing various printed matter anti-counterfeiting printing technology exists, the deficiency that the present invention is directed to the existence of existing printed matter anti-counterfeiting printing technology is improved prior art, propose the encryption counterfeit printing technology of the shape of a kind of scale-of-two coded signal modulation printed matter amplitude, anti-counterfeiting information is embedded in full page by the change of the shape of amplitude by this anti-counterfeiting printing technology, anti-counterfeiting information can be identified from any one fragment when printed matter identification, therefore there is very strong crush resistance, fundamentally can stop to adopt and take a picture, scanning waits bootlegging behavior.
The technical solution adopted for the present invention to solve the technical problems is: separately process the amplitude in flexographic printing hybrid screening and frequency-modulation halftone dot, utilize image information, Word message, the anti-counterfeiting information such as trademark information generate the scale-of-two anti-counterfeiting information table of 8 group, for preventing producing information spillover in ciphering process, in scale-of-two anti-counterfeiting information table 8 one group of binary message is expanded to 16 one group of binary messages, generate 16 the one group scale-of-two anti-counterfeiting information table that most-significant byte is 0 entirely, i-th group of 16 binary message in 16 one group scale-of-two anti-counterfeiting information table are denoted as N
