Embodiment

[0023] (1) Generate a group of 14 long random numbers Cn="77192347653540", produce a color sequence g[1]=black, g[2]=red, g[3]=green, g[4] composed of 4 colors ]=yellow, producing the EAN-13 commodity barcode (abbreviated as "commodity barcode") S="6901234567892" of 13 code lengths whose longitudinal length is H=22;

[0024] (2) obtain the binary sequence Bm to Cn according to the following algorithm: Bm=(∑(the bit sequence of each digital number among the place values ​​of each digital number among the Cn)) AND 4095, then have:

[0025] Bm=(7×1+7×2+1×3+9×4+2×5+3×6+4×7+7×8+6×9+5×10+3×11+5×12 +4×13+0×14) AND 4095

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

technical field [0001] The invention belongs to the technical field of digital anti-counterfeiting, in particular to a method for making a dynamic color commodity anti-counterfeiting mark. Background technique [0002] The current digital anti-counterfeiting technology is to generate a unique set of numbers for each product, that is, the product identity code, print the set of numbers on the product label or anti-counterfeiting mark through printing technology, and register the number corresponding to the number on the computer of the certification center. Product information, after the product is on the market, consumers send the number on the product label or anti-counterfeiting label back to the certification center for certification through the phone number, SMS special service number or network address published on the product label or anti-counterfeiting label. However, in actual operation, since code theft occurs from time to time, the credibility of digital anti-coun...
