Embodiment 1

[0064] According to the above-mentioned method for generating an anti-counterfeit code for a Chinese character product, the steps are as follows:

[0065](1) First, the Chinese character commodity identification code A = "江苏省##集团××subsidiary@@commodity production date 2020-02-01 production line 12 serial number 1 2 3 4 5 6 ”,逐个汉字转换为数值型数据,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}。

[0066] Then, convert the high-order numerical sequence P1 into 8-bit binary data element by element, and obtain the high-order binary sequence PB1={1,0,1,1,1,1,0,1,1,1,0,0,1,0 ,1,1,1,1,0,0,1,0,1,0,1,0,1,0,0,0,1,1,1,0,1,0,0,0,1 ,1,1,0,1,1,1,1,0,0,1...

Embodiment 2

[0088] According to the method for generating the anti-counterfeiting code of Chinese characters, the steps for generating the product identification code string A of a certain product and its product anti-counterfeiting code are similar to those in Embodiment 1, except that a certain external key changes slightly: α=0.12345000000001; or β= 3.74999999999999, the generation results of anti-counterfeiting codes for Chinese characters are shown in Table 1. It can be seen from the table below that once the external key changes slightly, the generated product anti-counterfeiting number and Chinese character product security code will change greatly. It can be seen that a method for generating Chinese character product security codes proposed in this patent is key-sensitive. sex.

Embodiment 3

[0094] According to the above-mentioned Chinese character product anti-counterfeiting code generation method, the external key and its product anti-counterfeiting code generation steps are similar to the specific embodiment 1. Production date 2020-02-01 Production line 12 serial number 1 2 3 4 5 6) Slight changes: "冮苏省##集团××subsidiary@@Commodity production date 2020-02-01 Production line 12 serial number 1 2 3 4 5 6"; or "Jiangsu Province ##Group ×× Subsidiary@@ Commodity Production Date 2020-12-01 Production Line 12 Serial Number 1 2 3 4 5 6"; or "Jiangsu Province ##Group ×× Subsidiary@@ @ Commodity production date 2020-02-01 Production line 12 serial number 1 2 3 4 5 9", the generation results of anti-counterfeiting codes in Chinese characters 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-counter...

Abstract

The invention discloses a Chinese character commodity anti-counterfeiting code generation method, which comprises the following steps of: performing numeric data and 8bits binary conversion on a Chinese character commodity recognition code A for representing unique identity information of a certain commodity; obtaining a binary sequence through binary supplement operation, obtaining an initial value and a parameter of a chaotic system through calculation, obtaining chaotic sequences X1 and X2 through extraction starting positions, extraction interval numbers and chaotic iteration, scrambling the binary sequence sum through utilization of position change rules before and after descending sort of the sequences X1 and X2, and obtaining a scrambled binary sequence sum; and respectively grouping the binary sequence and the middle elements in the forward direction by taking five elements as units, respectively recombining odd and even grouping sequences to generate commodity anti-counterfeiting numbers, and further generating the Chinese character commodity anti-counterfeiting codes in a combined manner. The Chinese character commodity anti-counterfeiting code generation method providedby the invention is simple and feasible, has strong security and is not easy to crack, and the generated Chinese character 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 anti-counterfeiting codes for Chinese-character commodities. 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 medicines delays...
