Abstract

The invention discloses a method for manufacturing dynamic colorful commodity anti-fake label. The method comprises the following step: (1) generating a group of n-digit numbers, a color sequence consisting of k colors and a 23-digit commodity bar code S with the longitudinal length of H; (2) Cn is subject to a first algorithm to obtain a binary sequence Bm, and the Bm and S are subject to a second algorithm to obtain an i-th color of S; (3) the longitudinal length H of S upwardly extends to H+R; (4) machine-readable stripes with the i-th color of S are sequentially printed at the height of R/13 in the region where the longitudinal length of S extends upwards; (5) black machine-readable stripes are printed in the region of the longitudinal length H of S; (6) human-readable characters with the i-th color of S are sequentially printed below the black machine-readable stripes; (7) and Cn is printed beyond the S on the anti-fake label. The method can improve the anti-fake strength of digits.

Description

A kind of method for making of dynamic colorful commodity anti-fake label

Technical field

The invention belongs to digital false-proof technology field, particularly a kind of method for making of dynamic colorful commodity anti-fake label.

Background technology

Current digital false-proof technology is to generate one group of unique number for each part product, it is product identification code, 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 problem and shortage of above-mentioned prior art existence, the object of this invention is to provide a kind of method for making of dynamic colorful commodity anti-fake label, number is converted to color sequence and is attached on bar code, improve digital false proof intensity.

Technical scheme: for achieving the above object, the method for making that the technical solution used in the present invention is a kind of dynamic colorful commodity anti-fake label, comprises the steps:

(1) produce one group of digital Cn that n position is long, n is not less than 5 positive integer, produces the look order g[1 of k color composition], g[2] ..., g[k], wherein k is not less than 3 positive integer, the long bar code S of 13 bit codes that to produce longitudinal length be H;

(2) logarithmic code Cn obtains binary sequence Bm by the first algorithm, and binary sequence Bm and bar code S are obtained to the i position color g[j of bar code S by the second algorithm _i], wherein i=1,2 ..., 13, j=1,2 ..., k;

(3) longitudinal length of bar code S is extended upwardly to H+R by H;

(4), in the upwardly extending region of longitudinal length of bar code S, take the height R/13 i position color g[j that print color is bar code S successively _i] machine-readable striped;

(5) the machine-readable striped of the region process black that is H at the longitudinal length of bar code S;

(6) below the machine-readable striped of black, print color is the i position color g[j of bar code S successively _i] people read character;

(7) digital Cn is printed on to the position beyond bar code S on anti-counterfeiting mark.

For guaranteeing enough false proof intensity, also make consumer be easy to identification, described n can be the positive integer that is not less than 8, and the value of described k can be 4.

For further increasing false proof intensity, in described step (7), also can be included in the step that the upper printing of described digital Cn can scrape coating off.

In described step (4), the described direction of printing successively can be from top to bottom.In described step (6), the described direction of printing successively can be from left to right.

Described bar code can be EAN-13 bar code.

When user buys product, scrape the coating on digital Cn off, by phone, short message or website etc., input successively digital Cn, first background computer inquires about the register information of Cn, if do not existed for vacation, as there is the i position color g[j that is obtained binary sequence Bm, the second algorithm acquisition bar code S by the first algorithm _i], the people of prompting user bar code S reads the color sequences of character and the color sequences of machine-readable striped prolongation, if be unanimously true, otherwise is false.

Beneficial effect: the present invention is in tradition on the basis by the digital code anti-false of the means of communication such as phone, mobile short-message, internet, by algorithm, digital code information be converted into color information and be attached on bar code, when inquiring about, number informs in the lump consumer, can greatly improve the false proof intensity of digital code anti-false, because digital document does not comprise color information, so robber code person only has number, be inadequate; Simultaneously, because bar code is the commodity requisite key elements that circulate, artificial destruction bar code can cause commodity normally to circulate, thereby suppresses the behavior that fake producer has a mind to cover, and under unsafe media and supervisor status, guarantee information is safe and reliable.

Accompanying drawing explanation

Fig. 1 is the schematic diagram (comprising coating) of dynamic color bar code of the present invention;

Fig. 2 is the schematic diagram (scraping off coating) of dynamic color bar code of the present invention.

In two accompanying drawings, the color of colored machine-readable striped is followed successively by black yellow yellow dark red green dark red greenish-yellow reddish yellow from top to bottom, and the color that people reads character is from left to right followed successively by black yellow yellow dark red green dark red greenish-yellow reddish yellow.

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) produce one group 14 long random number code Cn=" 77192347653540 ", produce the look order g[1 that 4 kinds of colors form]=black, g[2]=red, g[3]=green, g[4]=Huang, long EAN-13 bar code (being called for short " the bar code ") S=" 6901234567892 " of 13 bit codes that generation longitudinal length is H=22;

(2) Cn is obtained to binary sequence Bm:Bm=(∑ (in Cn in each digital place value * Cn the position order of each number) by following algorithm) AND 4095, have:
