Embodiment 1

[0083] According to the method for generating a product anti-counterfeit code encrypted with Chinese characters, the steps are as follows:

[0084](1) First, the product identification code A = "江苏省##集团××subsidiary@@commodity production date 2020-02-01 production line 12 serial number 123456", which represents the unique identity information of a certain product, is converted symbol by symbol into 数值型数据,得到高位数值序列P1={189,203,202,163,163,188,205,161,161,215,185,203,161,163,163,201,198,161,201,178,200,198,163,163,163,163,163,163,163,163,163,163,161,201,178,207,163,163,208,193,186,163,163,163,163,163,163}和低位数值序列P2={173,213,161,163,163,175,197,193,193,211,171,190,161,192,192,204,183,161,250,250,213,218,178,176,178,176,173,176,178,173,176,177,161,250,250,223,177,178,242,208,197,177,178,179,180,181,182}。

[0085] Then, the element P in the high-order value sequence P1 is sequentially added element by element i1 Convert to 8bits binary sequence {PB1 i1 ,PB1 i2 ,PB1 i3 ,PB1 i4 ,PB1 ...

Embodiment 2

[0108] According to the above-mentioned method for generating a product anti-counterfeit code encrypted with Chinese characters, the product identification code string A of a certain product and its product anti-counterfeit code generation steps are similar to the specific embodiment 1, only a slight change occurs in a certain external key: α=0.12345000000001 ; It can be seen from the table below that once the external key changes slightly, the generated product anti-counterfeiting number and product anti-counterfeiting code will change greatly. It can be seen that a method for generating a product anti-counterfeiting code encrypted with Chinese characters proposed in this patent has a key sensitivity.

[0109] Table 1 When the external key changes slightly, the product anti-counterfeiting code generation results

[0111]

Embodiment 3

[0113] According to the above-mentioned method for generating a product anti-counterfeiting code encrypted with Chinese characters, the steps of generating the external key and its product anti-counterfeiting code are similar to those in Embodiment 1, only the product identification code string A of a certain product undergoes a slight change: "冮苏州# #Group ××subsidiary@@commodity production date 2020-02-01 production line 12 serial number 123456"; or "Jiangsu Province##Group ××subsidiary@@commodity production date 2020-12-01 production line 12 serial number 123456" ; or "Jiangsu Province ##Group ×× Subsidiary @@ Product Production Date 2020-02-01 Production Line 12 Serial Number 123459", the product anti-counterfeiting code generation results are shown in Table 2. It can be seen from the following table: Once the product identification code character string representing the unique identity information of a certain product changes slightly, the generated product anti-counterfeit...

Abstract

The invention discloses a Chinese character encrypted commodity anti-counterfeiting code generation method, which comprises the following steps of: performing numeric data and 8bits binary conversionand binary combination operations on a Chinese character commodity identification code A representing unique identity information of a certain commodity to obtain a combined binary sequence PB; calculating to obtain an initial value, parameters, an extraction starting position and an extraction interval number of of a chaotic system, and carrying out chaotic iteration to obtain a chaotic sequenceY, scrambling a binary sequence PB by utilizing a position change rule before and after descending sorting of the sequence Y to obtain a scrambled binary sequence, and grouping the binary sequence bytaking eight elements as units in sequence in a forward direction; and respectively splitting and recombining the grouped sequences to generate commodity anti-counterfeiting numbers, and combining thecommodity anti-counterfeiting numbers to generate a commodity anti-counterfeiting code. The Chinese character encrypted commodity anti-counterfeiting code generation method is simple and feasible, has high safety and is not easy to crack, 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 commodity anti-counterfeiting code encrypted with Chinese characters. Background technique [0002] Counterfeit and shoddy products are common, and we need to take practical actions to protect the rights and interests of manufacturers and consumers. Counterfeit products pose a serious threat to various industries, especially pharmaceuticals, agricultural products, auto parts, computer software, and luxury goods such as expensive perfumes, cosmetics, jewelry, watches, and designer clothing. The International Chamber of Commerce in Geneva estimates that global sales of counterfeit products amount to $650 billion a year. Counterfeit medicines and alcoholic products are particularly problematic. This is not just counterfeiting. The actions of counterfeiters seriously endanger the rights and interests of consumers: counterfeiting of medic...
