The counterfeit product not only infringes the interests of the consumers and disturbs the normal market order, but also brings huge economic loss to manufacturers. In order to protect the benefit of each production enterprise from being damaged by counterfeit products, anti-counterfeiting codes are printed on the products mostly. When verifying the authenticity of the product, a consumer only needs to scrape off the covering layer of the anti-counterfeiting code, input the anti-counterfeiting code in the forms of a website, a telephone, a mobile phone short message and the like, and can obtain the authenticity result of the product through inquiry. At present, when anti-counterfeiting codes are inquired through websites, telephones and mobile phones, one number needs to be manually input, in the input process, due to the fact that the number of the coding bits is long, the situation that the codes are input by people is easily caused to be mistaken, sometimes, the situations that the telephone is not communicated, short messages are not replied and the like occur when the anti-counterfeiting codes are inquired through the telephone or the short messages of the mobile phones, and the inquiry is influenced to a great extent.

Along with the appearance of the two-dimensional code, the convenience of anti-counterfeiting verification is greatly facilitated. The surface and the inside of the existing valuable commodity are generally sprayed with two-dimensional codes to carry out anti-counterfeiting verification on the valuable commodity, and a merchant usually uses an anti-counterfeiting label on the commodity to help a consumer to identify the authenticity of the commodity. However, the anti-counterfeit label is stolen and largely copied to be used on counterfeit goods in the circulation process, so that the brand image of a merchant is damaged, and the benefit of consumers is also seriously influenced. Especially, the prior art has the defects of low security and easy embezzlement of the anti-counterfeit label.
