Problems solved by technology

[0002] In today's society, commodity counterfeiting and food and drug safety have increasingly become serious problems in the global economic field. It not only greatly damages the vital interests of manufacturers and consumers, disrupts market order, but also has a negative impact on brand building and maintaining social stability. came a very bad influence
The existing anti-counterfeiting code generation technology generally lacks the analysis and guarantee of the anti-attack performance of the encryption algorithm used, and the performance of the generated product anti-counterfeiting code still needs to be further improved, and the anti-counterfeiting effect is not satisfactory.

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 product is "A123456 2015-09-01 1234B0000001" and the length L=31, according to the correspondence between the custom product identification code characters and binary data in Table 1, the product with a length of 217 is obtained Identify the binary sequence P1 as {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 Hash value ...

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.

[0074] Table 3 The generation results of colored commodity anti-counterfeiting codes when the external key changes slightly

[0075]

[0076]

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 "A123456 2015-09-01 1234B0000002", "A1234562015-09- 02 1234B0000001" and "B123456 2015-09-02 1234B0000001"), the results of color commodity anti-counterfeiting codes 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.

Abstract

The invention discloses a colorful commodity anti-counterfeiting code generating method. The colorful commodity anti-counterfeiting code generating method comprises the following steps: converting a commodity identification code for representing the unique identity information of a certain commodity into a binary data; obtaining an initial value and parameters of a chaotic system based on the commodity identity information and an external secret key through calculation, and performing iteration on a chaotic mapping to generate two groups of chaotic signal binary sequences; performing bit manipulation taking 2bits as a unit on the commodity identification code by the chaotic binary signals to generate an anti-counterfeiting number overlapped with a colorful background, and further combining the anti-counterfeiting number into the colorful commodity anti-counterfeiting code. The colorful commodity anti-counterfeiting code generating method provided by the invention is simple, feasible, high in safety, and difficult to be cracked; and in addition, the generated colorful commodity anti-counterfeiting code is has the uniqueness and unforgeability.

Description

technical field [0001] The invention relates to the technical field of digital anti-counterfeiting, in particular to a method for generating a color commodity anti-counterfeiting code. Background technique [0002] In today's society, commodity counterfeiting and food and drug safety have increasingly become serious problems facing the global economy. It not only greatly damages the vital interests of manufacturers and consumers, disrupts market order, but also has a negative impact on brand building and maintaining social stability. There came a very bad influence. The existing anti-counterfeiting code generation technology generally lacks the analysis and guarantee of the anti-attack performance of the encryption algorithm used, the performance of the generated product anti-counterfeiting code still needs to be further improved, and the anti-counterfeiting effect is not satisfactory. At the same time, with the development of society, people's requirements for the appearan...
