Design And Realization Of Anti-fake Source Tracing Management System Based On NFC Technology

With the continuous development of science and technology,the means of forgery are also increasingly advanced.The existing anti-counterfeiting technology has been unable to meet the market demand,and a new set of security and feasibility is urgently needed.Combining with the mainstream software development technology,this thesis designs and implements anti-counterfeit traceability management system based on NFC technology.The system consists of NFC tag,NFC-enabled smart mobile device and cloud service center.NFC tag is used as the security information carrier and smart mobile device as the authentication terminal.Combined with the back-end database deployed in the cloud service,the system can complete the product authenticity verification and information traceability work.First of all,this thesis analyzes the requirements from the three aspects of anti-counterfeiting requirements,traceability requirements,and business management requirements.Then starting with the distribution process of the goods,the system user model is established and optimized according to the needs of different users.Based on the optimized user model,we designed a system framework composed of anti-counterfeiting carrier,verification terminal and cloud service center,as well as the system workflow from label authentication,information reading,encrypted communication to declassified traceability.Secondly,this thesis designs the anti-counterfeit traceability system in detail from three aspects of the client,the server and the security system.On the client side,this thesis designs two workflows that support the online mode under the network environment and the offline mode under the no-network environment;on the server side,the background software and database deployed on cloud services can complete the query and trace of products;In the aspect of system security,a label authentication scheme combining DH algorithm with AES algorithm and an encrypted network communication scheme combining AES algorithm with RSA algorithm are designed.Finally,this thesis has carried out the anti-counterfeiting traceability system,expounds the concrete realization process of the key function module,gave the actual realization renderings.The test process and test result of the system are also given.The realization of this system provides a safe and reliable platform for anti-counterfeiting detection for consumers,and has certain practical value.
