Embodiment 1
[0059] According to the method for generating the anti-counterfeiting code of colored commodities above, the steps are as follows:
[0060] (1) When the identification code A of a certain product is "A1234562015-09-011234B0000001", the length L=31, according to the correspondence between the custom product identification code characters and binary data in Table 1, the product identification binary with a length of 217 is obtained The sequence P1 is {1,0,0,0,0,0,1,0,1,1,0,0,0,1,0,1,1,0,0,1,0,0,1, 1,0,0,1,1,0,1,1,0,1,0,0,0,1,1,0,1,0,1,0,1,1,0,1,1, 0,1,1,1,1,1,1,1,0,1,1,0,0,1,0,0,1,1,0,0,0,0,0,1,1, 0,0,0,1,0,1,1,0,1,0,1,0,1,0,1,1,0,1,0,1,1,0,0,0,0, 0,1,1,1,0,0,1,0,0,0,1,1,0,0,0,1,1,0,0,0,0,0,1,1,0, 0,0,1,0,1,0,0,0,0,0,0,1,1,0,0,0,1,0,1,1,0,0,1,0,0, 1,1,0,0,1,1,0,1,1,0,1,0,0,1,0,0,0,0,1,0,0,1,1,0,0, 0,0,0,1,1,0,0,0,0,0,1,1,0,0,0,0,0,1,1,0,0,0,0,0,1, 1,0,0,0,0,0,1,1,0,0,0,0,0,1,1,0,0,0,1};
[0061] (2) Take the external key as Z 10 = 0.54321, Z 20 =0.56789, utilize the Has...
Embodiment 2
[0073] According to the method for generating the anti-counterfeit code of colored commodities described above, the steps for generating the identification code A of a certain commodity and its colored anti-counterfeit code are similar to those in Embodiment 1, except that a certain external key has a slight change: Z 10 = 0.543210000000001; or Z 20 =0.567890000000001, the generation result of the color commodity anti-counterfeiting code is shown in Table 3. It can be seen from the table below that once the external key changes even slightly, the generated color anti-counterfeiting number will change greatly, so it can be seen that the method for generating a color commodity anti-counterfeiting code proposed in this patent is sensitive to the key.

Embodiment 3
[0078] According to the method for generating the above-mentioned colored commodity anti-counterfeiting code, the steps of generating the external key and its colored anti-counterfeiting code are similar to those in Embodiment 1, and the slightly changed commodity identification code A (such as "A1234562015-09-011234B0000002", "A1234562015-09-021234B0000001" and "B1234562015-09-021234B0000001") to generate color product anti-counterfeit code results are shown in Table 4. It can be seen from the following table that slight changes in the commodity identification code will cause great changes in the color anti-counterfeiting number (including the anti-counterfeiting number string and color sequence), so it can be seen that a method for generating a colored commodity anti-counterfeiting code proposed in this patent has a great impact on the identity of the commodity. Information (i.e. item identifiers) is sensitive.
