Description
Technical field
The invention belongs to the digital false-proof technology field, the method for making of particularly a kind of gridline detection of dynamic sign indicating number 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; Should organize digital printing on Product labelling or anti-counterfeiting mark through printing technology; And on authentication center's computing machine the corresponding product information of this number of registration; Behind the launch, the consumer is sent back to authentication center with the number on Product labelling or the anti-counterfeiting mark and carries out authentication through being published in phone, note special service number or the network address on Product labelling or the anti-counterfeiting mark.But in practical operation, happen occasionally, the confidence level of digital code anti-false is reduced owing to steal sign indicating number.
Summary of the invention
Goal of the invention: to the above-mentioned existing problem and shortage that has technology; The method for making that the purpose of this invention is to provide a kind of gridline detection of dynamic sign indicating number sign and detection lug; With the additional relevant with it error detecting code of number and with the grid mode of printing error detecting code is hidden, can be improved the false proof intensity of digital code anti-false.
Technical scheme: for realizing the foregoing invention purpose, first kind of technical scheme that the present invention adopts is the method for making of a kind of gridline detection of dynamic sign indicating number sign (can be called for short " sign "), it is characterized in that comprising the steps:
(1) produce one group of digital Cn that the n position is long, n is not less than 5 positive integer, obtains the m long error detecting code Em in position through first algorithm, and m is not less than 5 positive integer;
(2) on sign, confirm error detecting code Printing Zone S1 and gridline spacing r;
(3) S1 prints gridline with spacing r in the error detecting code Printing Zone;
(4) error detecting code Em is write error detecting code Printing Zone S1;
(5) digital Cn is printed on sign and goes up the position beyond the S1 of error detecting code Printing Zone.
For further increasing false proof intensity, said n preferably is not less than 8 positive integer.
The width of said gridline can be 1 pixel.
Said step (4) can comprise:
1) in the S1 of error detecting code Printing Zone, confirms the less region S 2 of area, and S2 is placed the substantial middle position of S1;
2) print the profile shear plate P of said error detecting code Em with the font size that fully supports S2;
3) shear said gridline with said profile shear plate P, and by the distance of r/2 move down or on move said profile shear plate P;
4) in the S1 of error detecting code Printing Zone, print the white round dot that radius is r at random, quantity gets final product can cover Em.
The another kind of technical scheme that the present invention adopts is a kind of method for making of detection lug, and with spacing r printing gridline, said transparent film can cover said error detecting code Printing Zone S1 on transparent film.
The width of said gridline can be 1 pixel.
Can with mark label on product, detection lug be put into the packing of product at last.
When the user buys product; Import digital Cn successively through phone, short message or website etc., background computer is at first inquired about the register information of Cn, and obtains error detecting code Em by first algorithm; The prompting user covers detection lug in the error detecting code Printing Zone; Mobile detection lug makes the gridline of detection lug parallel with the gridline of error detecting code Printing Zone, if manifest Em for true, otherwise is false.
Beneficial effect: gridline detection of dynamic sign indicating number sign is on traditional digital code anti-false, to have added by the consumer to detect hiding Info of being associated through the medium prompting with detection lug; 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 does not comprise error detecting code; Simultaneously because the interference effect of gridline makes scanning duplicate thicken unclear.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Embodiment:
(1) generates 14 random number code Cn=" 11312439131831 ";
(2) adopt first algorithm to generate 8 error detecting code Em by Cn; Specific algorithm is: with per from right to left 8 volumes of digital Cn is one group, as if then supplying with 0 of 8 of less thaies in a high position, and two groups of digital additions that will generate; Generate one group 8 random number then; With the digital additions in two groups of fronts and make XOR with this random number of 8, the result and 100000000 with XOR does modular arithmetic again, promptly gets error detecting code Em:
Em＝((00113124+39131831)XOR?83325877)mod?100000000＝11257390；
(annotate: XOR is an XOR, and mod is modular arithmetic)
(3) make sign and detection lug:
As shown in Figure 1, delimit error detecting code Printing Zone S1 and confirm gridline spacing r (this Figure only shows the situation in the S1 of error detecting code Printing Zone) in the bottom of sign; In the S1 of error detecting code Printing Zone, begin by spacing r printing gridline (horizontal line) from the upper left corner, gridline is covered with error detecting code Printing Zone S1, and the density of gridline should be enough big, is enough to form the profile shear plate P that the back is mentioned; In the S1 of error detecting code Printing Zone, confirm the less region S 2 of area, and S2 is placed the substantial middle position of S1; Print error detecting code " 11257390 " the profile shear plate P of (not containing quotation marks, down together) with the font size that fully supports S2; Shear said gridline with said profile shear plate P, and move down said profile shear plate P (as shown in Figure 2) by the distance of r/2; In the S1 of error detecting code Printing Zone, printing radius at random is the white round dot of r, and quantity gets final product (as shown in Figure 3) can cover error detecting code; Digital " 11312439131831 " are printed on the top that sign goes up error detecting code Printing Zone S1, and as shown in Figure 4, sign completes.Make detection lug: with spacing r printing gridline, the size of this transparent film and shape and error detecting code Printing Zone S1 are basic identical, as shown in Figure 5 on transparent film.On product, detection lug is put into the packing of product with mark label.
When the user buys product; Import number 11312439131831 successively through phone, short message or website, background computer is at first inquired about this digital register information, and obtains 11257390 by first algorithm; The prompting user covers detection lug in the error detecting code Printing Zone; Mobile detection lug makes the gridline of detection lug parallel with the grid of error detecting code Printing Zone, if manifest 11257390 for true, otherwise is false (as shown in Figure 6).
