Description
Technical field:
The present invention relates to a kind of anti-counterfeiting printing technology, especially a kind of two dimensional code that line segmentation invalid code hides mutual-complementing code identification is anti-
Fake method can be used for the anti-fake of various printed matters.
Background technique:
Method for anti-counterfeit relatively common at present has following several: the first is laser anti-false sign, with laser recessiveness ink fluorescent
The symbol of product or special identification icon are printed to the anti-fake label of product by ink-printing techniques, 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, causes product
It is true and false to obscure, it is accordingly difficult to effectively anti-fake.Second is cipher counterfeit-proof labeling, and used method is that every product compiles one group
The coding of number, every product is different from, this number is printed on labeling and is covered, while can by this number deposit
For when consumer buys product, the number in mark is passed through phone or the meter that networks in the Computer Database of consumer query
Digital entering computer database in mark is compared identification by calculation machine, and identical is true, difference as vacation, method letter
Single, identification is easy, and is not easy to forge, but in actual use, prints labeling after generating because coded data is that computer is unified.It represents
The true and false coded data of product may be illegally duplicated fraud, meanwhile, the coding that coding also can be recycled on the product that do not inquire makes mark
And be attached on false pain product, antifalse effect it is difficult to ensure that.The third is texture anti-fake, anti-fake with the textural characteristics on its labeling, though
Right more difficult forgery, but the serial number due to being only marked with patch, and be plain code, every piece of mark can be inquired repeatedly, and fake producer can pass through warehouse
Phenomenon is copied the presence or absence of in the necessary textural characteristics i.e. grid reflected when administrator or shop-assistant are by serial number and inquiry on labeling
It is forged after attacking by this feature batch.
In conclusion existing method for anti-counterfeit all has some disadvantages, thus cannot be from preventing fake products at all.
Summary of the invention:
In order to overcome existing various printed matter anti-counterfeiting printing technologies there are the shortcomings that, the present invention is anti-for existing printed matter
Deficiency existing for pseudo- printing technology improves the prior art, proposes a kind of hiding mutual-complementing code identification of line segmentation invalid code
Dimension code anti-counterfeit method, which is divided into a width image in 2 D code with one or more cut-off rule complementary
Two blocks of images or muti-piece image, a portion printing image is on commodity, and another part printing image is a piece of or several thin
On plate together, it is clear that two blocks of images or reconsolidating for muti-piece image complementation are only constituted the complete two dimensional code figure of a width
Picture can just be obtained by scanning correct two-dimensional barcode information, and label can be effectively prevented by above-mentioned complementary identification, bill, have
The personation and abuse of valence security etc..
The technical solution adopted by the present invention to solve the technical problems is: a width two dimensional code is made of two-dimension code anti-counterfeit information
Former image in 2 D code is divided into complementary two blocks of images or more with one or more cut-off rule by image, referred to as former image in 2 D code
Block image, image in 2 D code area of a part of printing image generated after segmentation on commodity are known as short in size image, raw after segmentation
At another part printing image be known as complement code image on a piece of or several thin plates, and the thin plate for being printed with complement code image is claimed
For key, the complete former image in 2 D code of one width of composition that short in size image and complement code image can be complementary, the two dimensional code on commodity
It is left to fill invalid code image, short in size image and invalid code image construction one on a blank area in the position of image district original complement code image
Width pseudo- image in 2 D code identical with former image in 2 D code shape and area, pseudo- image in 2 D code is not the complete two dimensional code of a width
On image, it can not be obtained by scanning correct two-dimensional barcode information, only the merging of short in size image and complement code image complementation exists
Constitute together a width completely former image in 2 D code when, can just be obtained by scanning correct two-dimensional barcode information,
Due to being filled with invalid code image in blank area, pseudo- image in 2 D code and former image in 2 D code are without what from image
Difference, but pseudo- image in 2 D code cannot be obtained by scanning correct two-dimensional barcode information, due to being filled with invalid code in blank area
The external appearance characteristic of image, complement code image and short in size image has been hidden, and can not obtain complement code figure by pseudo- image in 2 D code
The information such as the shape feature of picture,
Above-mentioned cut-off rule is at least one or more straight line, curve and broken line,
Above-mentioned light sheet material refers to cardboard, plastic plate, aluminium sheet, iron plate, copper sheet and stainless steel plate etc.,
Illustrate the technical solution adopted by the present invention to solve the technical problems by taking zigzag cut-off rule as an example below, is prevented by two dimensional code
Fake information constitutes a width image in 2 D code, referred to as former image in 2 D code, by former image in 2 D code one zigzag cut-off rule point
The two zigzag image in 2 D code in left and right are segmented into, a part of zigzag image in 2 D code after segmentation is printed on the two dimension on commodity
Code image district is known as short in size image, and another part zigzag image in 2 D code after segmentation, which is printed on a piece of thin plate, is known as complement code
Image, and the thin plate for being printed with complement code image is known as to the key of short in size image, the weight that short in size image and complement code image can be complementary
The complete former image in 2 D code of one width of composition newly merged, the position of the image in 2 D code area original complement code image on commodity
Set on remaining blank area filling invalid code image, short in size image and one width of invalid code image construction and former image in 2 D code shape and
The identical pseudo- image in 2 D code of area, pseudo- image in 2 D code can not be obtained by scanning on the complete image in 2 D code of a width
Correct two-dimensional barcode information is taken, only the complement code image by short in size image and on the key, which is put together, constitutes the complete original two of a width
Code image is tieed up, correct two-dimensional barcode information can be just obtained by scanning,
In truth identification, complement code image on the key is placed on pseudo- image in 2 D code, is taken using complement code image on the key
Invalid code image on generation pseudo- image in 2 D code is simultaneously and short in size image constitutes the complete image in 2 D code of a width together, and by sweeping
It retouches and obtains correct two-dimensional barcode information, label can be effectively prevented by short in size image and the identification of complement code image complementation, bill, have
