Research And Design Of 2D Barcode Anti-counterfeiting System

A 2D barcode is made up by some specific geometric figures distributing, with certain regular rules, in 2 dimensional directions. It is an information carrier deriving from 1 dimensional barcode. 2D barcodes have some characteristics such like high density and strong error correction ability; it can be used to store a lot of information, and can be easily ported and recognized.With the popularization of computer, WWW, mobile phone and wireless communication, the 2D barcode has been applied in various fields. As the leader of the wireless communication field, China Mobile launched 2D barcode business in 2004, followed by DM (Data Matrix) code WAP-access application in 2006. With the characteristics of large information capacity, easy recognition, and the huge mobile phone market in China, the 2D barcode application is growing rapidly in China’s wireless communications industry after several years’ development.Anti-counterfeit is a new subject that many people are interested in it in modern merchandise society and it is also a difficult problem that a lot of well-known manufacturers spend much resource on it, such as energy, finance and human. The traditional means of anti-counterfeit updated continuously, such as laser anti-counterfeiting, version stripe anti-counterfeiting, and so on, which means anti-counterfeiting merchandise packaging or forgery cannot easily be forged, but they mainly rely on the person’s sense, so it is inconvenient to identify for the users, and it also increased production costs. The development of modern printing technology makes it easier for forged technologies, which means the traditional anti-counterfeit cannot meet the requirement of the manufacturers.According to the expected requirement, the merchandise anti-counterfeit must solve the following problem: First, to prove the authenticity of the product; second, to guarantee its uniqueness. As said above, to some extensive sense, the traditional anti-counterfeit labels are unavoidable to be forged, so the second problem is introduced, which puts and end to the spread of false merchandize by the uniqueness of merchandise, namely, each anti-counterfeit labels is different. In the counterfeit-check inquiry system, after checking the first issue, if the same check appeared again, it is determined to be fake, as in the definition of the anti-counterfeit system, every merchandise is given unique label information. The Online anti-counterfeit system based on 2D barcode can solve the above problem, and it is a new direction in current anti-counterfeit field.2D barcode anti-counterfeiting technology is a technology which realizes anti-counterfeiting through 2D barcode’s online applications. In the application of 2D barcode anti-counterfeiting technology, it is mainly to replace the traditional application of the digital security code with two-dimensional code, replace the traditional manual input with the mobile terminals with bar code scanning software, and replace the traditional telephone inquiries technology with the mobile internet technology. In addition, in order to support more users and get more benefit, users are supported to inquire in three ways as followings: inquiring by scanning 2D barcode, inquiring through internet and inquiring by SMS. 2D barcode anti-counterfeiting technology is mainly composed by anti-counterfeiting code, 2D barcode recognition software, 2D barcode platform, and 2D barcode anti-counterfeiting technology system.This paper focuses on the research and design of 2D barcode anti-counterfeiting system and the definition of interface between 2D barcode anti-counterfeiting system and 2D barcode platform. At the beginning, we conclude the problem of current anti-counterfeiting technology, analyze the ways of implementing 2D barcode anti-counterfeiting system, and then choose a suitable 2D barcode anti-counterfeiting system in accordance with the development of China’s national conditions. Finally, we introduce the principle of 2D barcode anti-counterfeiting technology, and based on the actual demand, design and implement a 2D barcode anti-counterfeiting system.
