Research And Application Development Of Key Technology Of Traceability System Based On Secure QR Code

The advent of the "Internet +" era,all kinds of goods can be sold through the Internet to all over the world.But in the process of commodity sales circulation,there are an endless stream of fake and shoddy events,which bring great distress to merchants and consumers.In order to protect the image of businessmen and safeguard the legitimate rights and interests of consumers,it is urgent to establish a set of effective anti-counterfeiting traceability system for the protection of merchants and consumers.At present,the traceability system of goods on the market emphasizes the unique identification of the product,that is,each commodity has a unique identification code.Through the unique logo to achieve the product from the production,sales,logistics,delivery and other life cycle process tracking,real-time tracking of all aspects of the commodity supply chain traceability,so as to better eliminate the emergence of commodity fake and shoddy.At present,the traceability system of goods in the market usually uses two-dimensional code instead of this unique logo,but the common QR two-dimensional code is easy to be copied,so there is still the phenomenon that can be falsified infringement.This paper mainly aims at this problem,using the author's laboratory research results-security QR code to replace the traditional QR two-dimensional code,this security QR code is called the same color heterogeneous spectrum security QR Code,this code in the ordinary light source to present a message,in the infrared light source to present another information,On the basis of this kind of code,this paper encrypts the code under the infrared light source as the safe QR code used in the object traceability system.This paper mainly studies the key technology of QR Code,studies the core module-two-dimensional code generation and reading module of the object traceability system,studies the key technologies of the system with high concurrency stability and security,and probes into the advantages of edge calculation applied to the traceability of items.Finally,the client-based item traceability WeChat program and the object traceability system based on PC end are realized.On the basis of the core module of item traceability,the object traceability system based on PC has added the mall subsystem and the Backstage User Portrait module,which realizes the tracking and traceability of the whole life cycle of goods from production processing to sales,logistics delivery,etc.,and this system has certain practical value.
