Design And Implementation Of Digital Card System Based On Internet Of Things

With the rapid development of computer t echnology and network technology,information technology is a far-reaching impact on the reform of management,especially in recent years,the development of Internet of things and smart card technology,in many occasions have been widely used.The digital campus has been developed rapidly,it will be the digital information resources,the network of information transmission and intelligent user terminal three systems organically combined.The use of the campus card system for the school to provide efficien t,convenient and safe management mode,has become an organic part of the campus construction,at the same time,this is not only for school administrators to provide information on the important way and means,but also support the implementation of school management and application.Through the common identity authentication mechanism,the integration and sharing of data management can be realized,which makes the card system used in the campus become an organic part of the information construction of the campus.By such an organic combination,we can avoid duplication of investment,improve the construction progress,and lay a foundation for the resource sharing between the system and the interconnection of the data.Digital card system started late in the university management application,the domestic smart card system compared with foreign countries there are still many problems,the main problems of standard,system is not compatible with each other,the use rate is low,it is difficult to share data an d poor security in information technology,aiming at the above problems,this paper on the digital campus card system the design and improvement,including system development background,research on the theoretical basis,the overall system design,detaile d design and system test of four parts,which focus on the construction of smart card system based on the contents of each subsystem are analyzed,and the main card Quancun query development machine the system has made the detailed design and implementatio n,through the improvement of key system,the two keys(PIN KEY and MAC KEY)respectively to encrypt the password field and the message checks,in order to reflect the nature of the platform,and meet the high level requirements of the school information management.Using J2 EE standard technology to build application system platform,C/S and B/S mixed mode as the system architecture,system software design,based on the existing digital campus card system,put forward the relevant suggestions,and successfully completed the relevant functional testing in a university,to provide the basis for further improvement and perfection.
