Embodiment 1

[0095] According to the above-mentioned method for generating the anti-counterfeiting code of character-type commodities, the steps are as follows:

[0096] (1) When the identification code A of a product is "B654321 2017-07-10abcd:111111", the length L=30, the numerical sequence A1={66,54,53,52,51,50,49,32, 50,48,49,55,45,48,55,45,49,48,32,97,98,99,100,58,49,49,49,49,49,49}, and each The value is converted to 7-bit binary to obtain a binary sequence AB={1,0,0,0,0,1,0,0,1,1,0,1,1,0,0, 1,1,0,1,0,1,0,1,1,0,1,0,0,0,1,1,0,0,1,1,0,1,1,0,0, 1,0,0,1,1,0,0,0,1,0,1,0,0,0,0,0,0,1,1,0,0,1,0,0,1, 1,0,0,0,0,0,1,1,0,0,0,1,0,1,1,0,1,1,1,0,1,0,1,1,0, 1,0,1,1,0,0,0,0,0,1,1,0,1,1,1,0,1,0,1,1,0,1,0,1,1, 0,0,0,1,0,1,1,0,0,0,0,0,1,0,0,0,0,0,1,1,0,0,0,0,1, 1,1,0,0,0,1,0,1,1,0,0,0,1,1,1,1,0,0,1,0,0,0,1,1,1, 0,1,0,0,1,1,0,0,0,1,0,1,1,0,0,0,1,0,1,1,0,0,0,1,0, 1,1,0,0,0,1,0,1,1,0,0,0,1,0,1,1,0,0,0,1};

[0097] (2) Take the external key K 10 =0.54321,K 20 = 0.56789 and K 30 =13, use the 16-bi...

Embodiment 2

[0119] According to the above method for generating the anti-counterfeiting code of character-type commodities, the steps of generating the identification code A of a certain commodity and the anti-counterfeiting code of character-type commodities are similar to the specific embodiment 1, and only a certain external key has a slight change: K 10 =0.543210000000001; or K 20 =0.567890000000001; or K 30 = 12, the generation result of the character-type product anti-counterfeiting code is shown in Table 4. It can be seen from the table below that once the external key changes even slightly, the generated character-type commodity anti-counterfeiting number will change greatly. It can be seen that the method for generating the character-type commodity anti-counterfeiting code proposed in this patent is sensitive to the key.

[0120] Table 4 When the external key changes slightly, the generation result of the character-type product anti-counterfeiting code

[0121]

[0122]

Embodiment 3

[0124] According to the method for generating the above-mentioned character-type commodity anti-counterfeiting code, the generation steps of the external key and the character-type anti-counterfeiting code thereof are similar to those in Embodiment 1, and the slightly changed commodity identification code A (such as 'b654321 2017-07-10abcd:111111', 'B6543212017 -07-11abcd:111111' and 'B654321 2017-07-10abcd:111112') the results of character-type product anti-counterfeiting codes are shown in Table 5. It can be seen from the following table that a slight change in the product identification code will cause a large change in the character-type product anti-counterfeiting number, so it can be seen that a method for generating a character-type product anti-counterfeiting code proposed in this patent does not affect the product identity information (that is, the product identification code). Sensitive.

[0125] Table 5 When the commodity identification code changes slightly, the ge...

Abstract

The invention discloses a method for generating a character type commodity anti-counterfeiting code. The method comprises the following steps of converting a character type commodity identification code for representing unique identity information of a commodity into a binary sequence; utilizing the identity information of the commodity and external keys to compute in order to obtain initial values, parameters and extraction intervals of a chaotic system and generating two groups of chaotic signal binary sequences after iteration of chaotic mapping; and carrying out grouping the binary sequences in 7bits, generating a commodity encryption value through the first 3bits while carrying out corresponding mapping and coding and two bit operations on the latter 4bits in 2bits according to a user-defined 2bits encoding rule correspondence and a user-defined bit operation rule correspondence, and obtaining a character type commodity anti-counterfeiting number according to the correspondence between the user-defined commodity encryption value and a commodity encryption number in order to be combined to the character type commodity anti-counterfeiting code. The method for generating the character type commodity anti-counterfeiting code has the advantages of strong security and difficulty in cracking, and the generated commodity anti-counterfeiting code has 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 character-type commodity anti-counterfeiting code. Background technique [0002] Since the reform and opening up, the speed and level of China's economic development have changed with each passing day, which has greatly enriched the material living standards of the people. While economic development has brought us benefits, it has also produced adverse effects. Driven by economic interests, all kinds of counterfeit and shoddy goods emerge in an endless stream, which not only damages the interests of consumers, but also brings reputation damage to the counterfeit brands, resulting in economic losses and seriously affecting the corporate image. In order to protect the interests of manufacturers and consumers, anti-counterfeiting issues arise at the historic moment and receive more and more attention. [0003] Counterfeiting is a night...
