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

With the development of the national economy,the issue of the production and distribution of counterfeited products has become increasingly prominent.The traditional anti-counterfeiting technology has difficulty to figure it out,a safe and effective new program is urgently needed.This paper designs and establishes an anti-counterfeit traceability platform based on NFC technology combined with the smart card technology of Internet.Using NFC smart tags and fragile antennas to form a security information carrier,with a NFC-enabled smart device as a verification terminal,combined with the background database deployed in cloud servers,uses can trace the information of products and identify authenticity.The innovation of this paper is summarized as follows:(1)Using NFC tags as a source of anti-counterfeiting information,the label information can be dynamically added or modified to complete the encryption and decryption operation.To trace the whole process of circulation and achieve anti-counterfeiting;(2)Design a dual authentication scheme on the basis of DH algorithm and 3DES algorithm,it can support the authentification of products from client-side in off-line working mode without network.This paper starts from the process of product distribution,and builds and optimizes the systematic user model according to the needs of different users.And it designs the system framework composed of information source,authentication terminal and cloud service center,and the systematic workflow which includes label authentication,information reading,encryption communication and decryption traceability.Specifically,this paper completes the design of anti-counterfeit information source on the basis of the NFC smart card and fragile substrate antenna technology.In terms of the client side,the hardware adopts the NFC full terminal program with good security and compatibility.The software supports two workflows of online mode and offline mode;in the service side,the background software and database deployed on cloud services can complete the query and trace of products;as for the system security,it uses specially designed network communication Message structure,combined with the double label authentication scheme based on DH algorithm and 3DES algorithm,and the encryption network communication scheme based on RSA algorithm and 3DES algorithm.At the end of this paper,it shows the code of key modules of the system and the actual realization images.The system provides consumers a safe,reliable,easy operating mean of authenticity detection of products,and improves the informalization of quality management system.
