Realization And Design Of Security And Traceability Based On Two-Dimensional Code Technology

At present,China has nearly 350 million smokers,tobacco production and sales accounted for nearly 1/3 of world market share.However,in recent years,international and domestic food safety problems have occurred frequently,especially fake and shoddy tobacco products,so that people are worried about the safety of tobacco products purchased.Therefore,ensuring the quality and safety of tobacco products is the top priority.According to the characteristics of anti-counterfeit and traceability system and the actual situation of today's tobacco industry in China,this paper analyzes the whole process of tobacco products from planting to production,and analyzes the business needs and functional requirements.Based on that,a tobacco counterfeiting and tracing system based on two dimensional code technology is designed and implemented,and the two-dimensional code information anti-counterfeiting scheme is researched.The system is divided into two parts,which are anti-counterfeit and traceability information acquisition client system and backstage management system.It includes a series of functions,such as user addition and management,information collection and input,data query and management,and system positioning.Through the study of networking technology in tobacco planting,transportation,processing and sales in the process of use,real-time acquisition and recording of information.Secondly,records the information of tobacco products using two-dimensional code to use two-dimensional code technology,and pasted on the cigarette package above,making consumers by scanning the two-dimensional code on the package of smoke authenticity and traceability of information products.The results show that in tobacco products planting,production and circulation in the use of networking technology and two-dimensional code technology can not only control and supervision of tobacco planting in the production process of raw materials quality,procurement,storage and production of various links,effectively improve the tobacco planting of the product quality and production efficiency,but also can make consumers to identify the authenticity and traceability query to his purchase of tobacco products.In addition,market regulators can also effectively supervise the legitimate and efficient production operations of tobacco enterprises,and tobacco enterprises can also improve the production process and improve the quality of products.
