Description
Technical field
The invention belongs to digital false-proof technology field, particularly the method for making of a kind of gridline detection of dynamic code sign and detection lug.
Background technology
Digital false-proof technology is to be product identification code for each part product generates one group of unique number, by printing technology, this is organized to digital printing on Product labelling or anti-counterfeiting mark, on Bing authentication center computing machine, register the product information of this number correspondence, after launch, consumer, by being published in phone, note special service number or the network address on Product labelling or anti-counterfeiting mark, is sent back to authentication center by the number on Product labelling or anti-counterfeiting mark and authenticates.But in practical operation, owing to stealing code, happen occasionally, the confidence level of digital code anti-false is reduced.
Summary of the invention
Goal of the invention: for the above-mentioned existing problem and shortage that has technology, the method for making that the object of this invention is to provide a kind of gridline detection of dynamic code sign and detection lug, the error detecting code that number is additional associated is also hidden error detecting code with grid mode of printing, can be improved the false proof intensity of digital code anti-false.
Technical scheme: for achieving the above object, the first technical scheme that the present invention adopts is the method for making of a kind of gridline detection of dynamic code sign (can be called for short " sign "), it is characterized in that comprising the steps:
(1) produce one group of digital Cn that n position is long, n is not less than 5 positive integer, by the first algorithm, obtains the long error detecting code Em in m position, and m is not less than 5 positive integer;
(2) in sign, determine error detecting code Printing Zone S1 and gridline spacing r;
(3) at error detecting code Printing Zone S1, with spacing r, print gridline;
(4) error detecting code Em is write to error detecting code Printing Zone S1;
(5) digital Cn is printed on to the upper error detecting code Printing Zone S1 of sign position in addition.
For further increasing false proof intensity, described n is preferably not less than 8 positive integer.
The width of described gridline can be 1 pixel.
Described step (4) can comprise:
1) in the S1 of error detecting code Printing Zone, determine the less region S2 of area, and S2 is placed in to the substantial middle position of S1;
2) to fully support the font size of S2, print the profile shear plate P of described error detecting code Em;
3) with described profile shear plate P, shear described gridline, and by the distance of r/2 move down or on move described profile shear plate P;
4) the white round dot that random printing radius is r in the S1 of error detecting code Printing Zone, quantity is can cover Em.
The method for making that the another kind of technical scheme that the present invention adopts is a kind of detection lug, on transparent film, with spacing r printing gridline, described transparent film can cover described error detecting code Printing Zone S1.
The width of described gridline can be 1 pixel.
Finally can, by mark label on product, detection lug be put into the packing of product.
When user buys product, by phone, short message or website etc., input successively digital Cn, first background computer inquires about the register information of Cn, and obtain error detecting code Em by the first algorithm, prompting user covers detection lug in error detecting code Printing Zone, mobile detection lug makes the gridline of detection lug parallel with the gridline of error detecting code Printing Zone, is true, otherwise is false if manifest Em.
Beneficial effect: gridline detection of dynamic code sign is to have added by consumer to be pointed out with detection lug and detected hiding Info of being associated by media on traditional digital code anti-false, can greatly improve the false proof intensity of digital code anti-false, because steal-number person not only wants printed digital, and must obtain error detecting code, but digital document inclusion test code not; Simultaneously because the interference effect of gridline makes to scan duplicate, thicken unclear.

Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment is only not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
Embodiment:
(1) generate the random number code Cn=" 11312439131831 " of 14;
(2) by Cn, adopt the first algorithm to generate the error detecting code Em of 8, specific algorithm is: by digital Cn from right to left every 8 volumes be one group, if supplying with 0 in a high position of 8 of less thaies, and by two groups of digital additions that generate, then generate the random number of a group 8, by above two groups digital that be added and make XOR with this random number of 8, then the result of XOR and 100000000 is done to modular arithmetic, obtain error detecting code Em:
Em＝((00113124+39131831)XOR?83325877)mod?100000000＝11257390；
(noting: XOR is XOR, and mod is modular arithmetic)
(3) make sign and detection lug:
As shown in Figure 1, in the bottom of sign, delimit error detecting code Printing Zone S1 and determine gridline spacing r (this Figure only shows the situation in the S1 of error detecting code Printing Zone); In the S1Nei Cong upper left corner, error detecting code Printing Zone, start by spacing r printing gridline (horizontal line), gridline is covered with error detecting code Printing Zone S1, and the density of gridline should be enough large, is enough to form the profile shear plate P mentioning below; In the S1 of error detecting code Printing Zone, determine the less region S2 of area, and S2 is placed in to the substantial middle position of S1; To fully support the profile shear plate P of the font size printing checking code " 11257390 " (not containing quotation marks, lower same) of S2; With described profile shear plate P, shear described gridline, and move down described profile shear plate P (as shown in Figure 2) by the distance of r/2; The white round dot that random printing radius is r in the S1 of error detecting code Printing Zone, quantity gets final product (as shown in Figure 3) can cover error detecting code; The top that digital " 11312439131831 " is printed on to the upper error detecting code Printing Zone S1 of sign, as shown in Figure 4, sign completes.Make detection lug: with spacing r printing gridline, the size and shape of this transparent film and error detecting code Printing Zone S1 are basic identical, as shown in Figure 5 on transparent film.By mark label, on product, detection lug is put into the packing of product.
When user buys product, by phone, short message or website, input successively digital 11312439131831, first background computer inquires about this digital register information, and obtain 11257390 by the first algorithm, prompting user covers detection lug in error detecting code Printing Zone, mobile detection lug makes the gridline of detection lug parallel with the grid of error detecting code Printing Zone, is true, otherwise is false (as shown in Figure 6) if manifest 11257390.
