Problems solved by technology

There is following shortcoming in the anti-counterfeiting of this commodity: 1) in the digital anti-counterfeiting system of existing commodity, the inquiry of logistics and anti-false cargo monitoring information is realized by the inquiry process of commodity authenticity
Although the use of hidden carriers of anti-counterfeiting codes such as digital anti-counterfeiting chips, IC cards, and magnetic cards can prevent counterfeiters from recycling uninquired anti-counterfeiting codes, the cost of digital anti-counterfeiting technology based on electronic concealed carriers is relatively high and requires customers to have special inputs. equipment, it is difficult to popularize at present
3) The verification of the authenticity of the product is only a one-way verification. The main body to verify the authenticity of the product is the remote digital anti-counterfeiting center, and the verification process of the digital anti-counterfeiting center is a suspicious black box for the inquirer, that is, when the verification party is a When an illegal digital anti-counterfeiting verification center is used, the inquirer cannot be sure of the authenticity of the verification

Embodiment Construction

[0026] According to the production period, batch, inspection level, raw material, manufacturer code, commodity code, etc. of the product, the manufacturer generates a unique ID code for the product: 2541258024. Significant printing or spraying on the surface of commodity packaging. Randomly construct a seventh-order magic square M for this numbered commodity, as shown in Figure 1. Then randomly generate a corresponding seven-order shuffled square matrix S for the magic square M, as shown in Figure 2. Shuffle the square matrix S to decompose the magic square M into defect magic square M 1 Complementary Defect Magic Square M 2 , see Figures 3 and 4. Will print defective magic square M 1 The cards are hidden in the packaging, and the defective magic square filling cards are shown in Figure 5; the shuffling matrix S is converted into a shuffling vector (1, 0, 1, 0, 0, 1, 0, 0, 1, 0, 1, 1,0,1,0,1,1,0,1,0,0,1,0,0,1,0,1,1,1,1,0,0,1,1,0,0, 0, 1, 1, 0, 0, 1, 1, 1, 0, 0, 1, 0, 0),...

Abstract

The invention discloses a commodity numeral fake prevention method. It includes the following steps that firstly, the uniqueness identity code delegated commodity identity is set dominantly on the commodity; secondly, the commodity fake prevention code is recessively printed or jetted on the opening of the commodity that is deciduousable seal, stay-guy, or card concealed in the package, this can make the commodity identity code be separated from the identity fade prevention code after it is used; finally, when the commodity are verifying, the uniqueness identity code is input, the name, manufactures, producing areas, batch, production dada can be inquired, the uniqueness identity code and fake prevention code of the commodity are input to inquire whether it's genuine or fake. The applying cost of the digital fake prevention method is low. This can satisfy the demand of monitoring physical distribution and change prevention for the manufactures, also can effectively prevent the fake maker from reclaiming the fake prevention code of the commodity package which are not inquired to make fake in batch production.

Description

technical field [0001] The invention relates to an anti-counterfeiting method for commodities, in particular to a digital anti-counterfeiting method for commodities. Background technique [0002] Digital anti-counterfeiting technology, also known as code or telephone anti-counterfeiting, is a high-tech anti-counterfeiting technology that comprehensively utilizes advanced digital coding, encryption, database, computer network, communication and computer voice processing technologies. Digital anti-counterfeiting is the most popular anti-counterfeiting technology in China at present, and it is a key promotion project of the country. Digital anti-counterfeiting verification is divided into two methods, namely algorithm verification and storage verification. Anti-counterfeit codes with autocorrelation generally verify their legitimacy through corresponding encryption algorithms; random anti-counterfeit codes without autocorrelation generally check the an...
