Commodity forgery prevention method based on two-dimensional codes

Abstract

The invention discloses a commodity forgery prevention method based on two-dimensional codes, and relates to the technical field of forgery prevention. The method aims at improving a forgery prevention effect. The method comprises the steps that a unique two-dimensional code is printed on each commodity; the two-dimensional codes of the commodities are stored in a forgery prevention database of an authentication server; a commodity purchaser scans the two-dimensional codes on the commodities by utilizing a terminal; the two-dimensional codes are sent to the authentication server for authenticating the authenticity of the commodities; an authentication times threshold is set for each two-dimensional code in the forgery prevention database of the authentication server; after the two-dimensional code of one commodity is authenticated successfully once, the authentication server subtracts one from the authentication times threshold of the two-dimensional code of the commodity, and returns authentication success information to a user; and after the authentication success times of the two-dimensional code of one commodity exceed an initial value of the authentication times threshold, the two-dimensional code of the commodity is invalid. The method is low in forgery prevention cost and good in forgery prevention effect.

Description

technical field [0001] The invention relates to an anti-counterfeiting technology, in particular to a technology of a commodity anti-counterfeiting method based on a two-dimensional code. Background technique [0002] At present, many companies have printed two-dimensional codes on their products or product packaging boxes. After consumers purchase products, they can use the two-dimensional code scanning terminal to scan the two-dimensional code on the product, and then according to the scanned two-dimensional code information , to verify the authenticity of the purchased products through mobile phone text messages or the Internet. [0003] The two-dimensional code anti-counterfeiting method currently on the market has the following defects: in the existing two-dimensional code anti-counterfeiting method, the two-dimensional code printed on the commodity can be inquired repeatedly indefinitely, in order to prevent counterfeiters from also printing the same Two-dimensional c...

Problems solved by technology

[0003] The two-dimensional code anti-counterfeiting method currently on the market has the following defects: in the existing two-dimensional code anti-counterfeiting method, the two-dimensional code printed on the commodity can be inquired repeatedly indefinitely, in order to prevent counterfeiters from also printing the same Two-dimensional code, the existing two-dimensional code labels are made of special materials or processes such as anti-counterfeiting ink and fragile paper, which makes the cost of two-dimensional code anti-counterfeiting rise, and will hinder the recirculation of products in the market after verification of authenticity , and although this technology increases the counterfeiting cost of imitators, there is still the possibility of counterfeiting

It can be seen that the anti-counterfeiting effect of the existing two-dimensional code anti-counterfeiting method still needs to be improved
