Embodiment 1
[0076] According to the batch generation method of product anti-counterfeiting codes above, the steps are as follows:
[0077] (1) When the batch commodity identification code of a certain batch of commodities is coded as "A123E1212342014-12-26d19", the length L=25, and the production serial number numerical sequence B of this batch of commodities is set at the same time, wherein each element starts from 0 and increases by 1, Its length is 10 5 ;
[0078] (2) According to the correspondence between the custom batch commodity identification code characters and numerical data in Table 1, the numerical sequence S1 is obtained as {10, 1, 2, 3, 14, 1, 2, 1, 2, 3, 4, 2,0,1,4,63,1,2,63,2,6,62,39,1,9};
[0079] (3) The numerical sequence of the production serial number of this batch of commodities is scrambled:
[0080] Get the key (Z 11 = 0.12345, Z 12 =0.56789), using the batch commodity identity information and key, according to the formula in step (3) of the above-mentioned c...
Embodiment 2
[0106] According to the method for batch generation of commodity anti-counterfeit codes, the batch generation steps of batch commodity identification codes and their anti-counterfeit codes are similar to the specific embodiment 1, and only a certain key has a slight change: Z 11 = 0.12345000000001; or Z 12 = 0.56789; or Z 21 = 0.12345; or Z 22 = 0.56789; or Z 31 = 0.23456; or Z 32 = 0.45678, the generation results of the commodity anti-counterfeiting code are shown in Table 5. It can be seen from the following table: once the key changes even slightly, that is, "missing by a tiny bit", the production serial number of the product after the scrambling or the anti-counterfeiting number of the product generated will be "different". The batch generation method of commodity anti-counterfeiting code is sensitive to key.

Embodiment 3
[0111] According to the method for generating anti-counterfeiting codes in batches described above, the steps for generating keys and anti-counterfeiting codes in batches are similar to those in Embodiment 1, and only the identification codes of the batches of commodities are slightly changed (such as "B123E1212342014-12-26d19", "A123E1212342014-12-26d18" and "A123E1212322014-12-26d19"), the generated anti-counterfeit code results are shown in Table 6. It can be seen from the following table that slight changes in the batch commodity identification codes will cause great changes in the commodity anti-counterfeiting numbers, thus it can be seen that a method for batch generation of commodity anti-counterfeiting codes proposed in this patent can be used for identity information of a certain batch of commodities (i.e. batch commodity identification). code) is sensitive.
