Design And Implementation Of Commodity Anti-counterfiet And Information Management System Based On NFC Tags

Sales enterprise is an important part of the market.With the popularization of enterprise management system,and the development of related technologies in the field of Internet of things,it has become an urgent demand for many sales enterprises to carry out the commodity information management based on the Internet of things.Sales enterprises want to use a more lightweight,low-cost,mobile,highly convenient commodity information management system.At the same time,many enterprises need to carry out commodity anti-counterfeiting,put forward the demand for the commodityinformation management system to add anti-counterfeiting feature.Based on the above background,this thesis puts forward a design scheme of commodity anti-counterfeit and information management system based on NFC tags.The program meets the needs of the administrators of the sales enterprises and consumers,and has high practical value.The main contents include the research and improvement of NFC tag based commodity anti-counterfeiting technology,the design and implementation of commodity information management system based on NFC tags:First,analysed the need from enterprise administrators and consumers before the development of the system,based on the analyse results designed the NFC tag commodity information management system.On the basis of the traditional management system model,proposesed a dual architecture optimization model based on NFC tags.On the basis of this model,the specific functions of the system have been set up,and the specific system development program has made.Second,compared the difference between RFID and NFC tags,clear the NFC tag based anti-counterfeiting scheme.Analysed the NFC tag anti-counterfeiting scheme based on AES and RSA algorithm,then proposes an improved NFC tag anticounterfeiting scheme based on the mixed algorithm with AES and RSA.The security performance of the scheme is improved by optimizing the AES algorithm and adding the NFC tag password protection.Finally,based on the design of the commodity management information system based on NFC tags were developed,includes the development of commodity management system based on SSM framework and the NFC tags identifiable Android client.The specific content of the development includes the construction of the system database,set up the background server,development of the management system website and Android client.In order to avoid the problem of blocking the main thread in the communication between the Android client and the NFC tag,an optimization scheme for the asynchronous task processing of the NFC tag communication operation has been put forward.The system test shows that the commodity anti-counterfeit and information management system based on NFC tag has the advantages of light weight,low cost,high efficiency and convenience.The system runs stably and has high flexibility and practical application value.For the sale of enterprises to provide an ideal commodity anti-counterfeiting and information management system solution.
