Problems solved by technology

The existing digital anti-counterfeiting technology basically uses a pseudo-random sequence or an ordered serial number to generate an anti-counterfeiting code through DES symmetric encryption, which has a certain gap with the performance requirements of "unforgeability and uniqueness" of the anti-counterfeiting code in digital anti-counterfeiting technology. ; The vast majority of existing product anti-counterfeiting code generation methods are anti-counterfeiting code generation algorithms proposed for a single commodity, the calculation is more complicated, and the safety of generating commodity anti-counterfeiting codes between certain batches of commodities and between batches of commodities is not considered and computational efficiency, it is difficult to apply it in the actual production of batch commodities

Embodiment 1

[0076] According to the batch generation method of product anti-counterfeiting codes above, the steps are as follows:

[0077] (1) When the batch commodity identification code of a certain batch of commodities is coded as "A123E1212342014-12-26d19", the length L=25, and the production serial number numerical sequence B of this batch of commodities is set at the same time, wherein each element starts from 0 and increases by 1, Its length is 10 5 ;

[0078] (2) According to the correspondence between the custom batch commodity identification code characters and numerical data in Table 1, the numerical sequence S1 is obtained as {10, 1, 2, 3, 14, 1, 2, 1, 2, 3, 4, 2,0,1,4,63,1,2,63,2,6,62,39,1,9};

[0079] (3) The numerical sequence of the production serial number of this batch of commodities is scrambled:

[0080] Get the key (Z 11 = 0.12345, Z 12 =0.56789), using the batch commodity identity information and key, according to the formula in step (3) of the above-mentioned c...

Embodiment 2

[0106] According to the method for batch generation of commodity anti-counterfeit codes, the batch generation steps of batch commodity identification codes and their anti-counterfeit codes are similar to the specific embodiment 1, and only a certain key has a slight change: Z 11 = 0.12345000000001; or Z 12 = 0.56789; or Z 21 = 0.12345; or Z 22 = 0.56789; or Z 31 = 0.23456; or Z 32 = 0.45678, the generation results of the commodity anti-counterfeiting code are shown in Table 5. It can be seen from the following table: once the key changes even slightly, that is, "missing by a tiny bit", the production serial number of the product after the scrambling or the anti-counterfeiting number of the product generated will be "different". The batch generation method of commodity anti-counterfeiting code is sensitive to key.

[0107] Table 5 When the key changes slightly, the product anti-counterfeiting code generation results

[0109]

Embodiment 3

[0111] According to the method for generating anti-counterfeiting codes in batches described above, the steps for generating keys and anti-counterfeiting codes in batches are similar to those in Embodiment 1, and only the identification codes of the batches of commodities are slightly changed (such as "B123E1212342014-12-26d19", "A123E1212342014-12-26d18" and "A123E1212322014-12-26d19"), the generated anti-counterfeit code results are shown in Table 6. It can be seen from the following table that slight changes in the batch commodity identification codes will cause great changes in the commodity anti-counterfeiting numbers, thus it can be seen that a method for batch generation of commodity anti-counterfeiting codes proposed in this patent can be used for identity information of a certain batch of commodities (i.e. batch commodity identification). code) is sensitive.

Abstract

The invention discloses a commodity anti-counterfeiting code batch generation method which comprises the following steps: encoding identity information of a certain batch of commodities to generate a batch of commodity identification codes and setting a commodity production-sequence-number numerical sequence with a certain length; according to a corresponding relation of custom batch commodity identification code characters and numeric data, converting the batch of commodity identification codes into a numerical sequence; respectively carrying out scrambling on ciphertext characters in a corresponding relation among the production-sequence-number numerical sequence, the custom numeric data and the ciphertext characters of a certain batch of commodities by utilizing a position variation scrambling rule before and after chaos sequences are sorted; enabling each commodity in the batch of commodities to sequentially carry out displacement and scrambling on the transcoded numerical sequence according to the corresponding chaos sequences and the position variation scrambling rule before and after the chaos sequences are sorted and generating an anti-counterfeiting number of each commodity so as to combine and produce commodity anti-counterfeiting codes in batch. The method disclosed by the invention is simple and easy to operate, has high safety and is unlikely to crack; the commodity anti-counterfeiting codes generated in batch have uniqueness and unforgeability.

Description

technical field [0001] The invention relates to the technical field of digital anti-counterfeiting, in particular to a batch generation method of commodity anti-counterfeiting codes. Background technique [0002] In today's society, counterfeit goods are prevalent, counterfeiting has become a flooding trend, and food and drug safety accidents occur frequently. How to realize anti-counterfeiting of commodities, eliminate counterfeiting, recover the economic losses of the country and enterprises, and protect the rights and interests of consumers is a global issue that urgently needs to be studied and solved. The problem. The existing digital anti-counterfeiting technology basically uses a pseudo-random sequence or an ordered serial number to generate an anti-counterfeiting code through DES symmetric encryption, which has a certain gap with the performance requirements of "unforgeability and uniqueness" of the anti-counterfeiting code in digital anti-counterfeiting technology. ...
