Research And Application Of Commodity Security Based On Two Dimensional Code

As Internet has been developed quickly,the rapid growth of commodity trading volume,Especially the online shopping crowd expanded year by year,but it has brought the emergence of fake and shoddy goods,a large number of illegal traders fight unafraid against the law,in the face of counterfeit goods brought huge benefits,illegal people take the risk of inferior products production and sales.For consumers how to identify the authenticity of goods has become troubled,commodity security system for consumers is essential.Take advantage of database technology and network communication technology to become the backbone of security,as the carrier of information storage,two-dimensional code through the standardized coding format to store the information needed to image in the form of information to the outside world,The two-dimensional code is composed of light and dark blocks,so people cannot identify the information through the eyes,in a way,the expression of this information on the encoded information played a certain security function,With the popularity of smart phones,and the combination of two-dimensional code to become an important way of commodity security.Through the analysis of the current security system,due to the popularity of smart phones,so choose to run on the android operating system,Combined with two-dimensional code technology,image recognition technology,database technology,Design and development of commodity security system based on two-dimensional code.The system analysis mainly picture of anti-counterfeit two-dimensional code of the product stored on the mobile phone,taking into account the need to accurately locate the picture of the two-dimensional code position and its decoding verification,the first need to image this image Preprocessing,including color space conversion,binary image,expansion and corrosion operations,and finally positioning to the image of the location of anti-counterfeit two-dimensional code,according to the two-dimensional code decoding rules to decode,Not only for the existing two-dimensional code to resolve,but also the system generated anti-counterfeit two-dimensional code,the system provides users with a unique product identification,while the ID and the corresponding commodity information added to the self-built database.while verification,The consumer by the Http request send ID to the background for verification.Return the basic information and verify the results of goods,consumers identify the authenticity by information.Through the feasibility and safety analysis of the system and the final experiment,it is proved that the system can realize the anti-counterfeiting function.
