Design And Implementation Of Mobile Payment System Based On The Android Mobile Phone

With the 863 national smarter city project as an opportunity, this paper proposed the design and implementation of mobile payment system based on the Android mobile phone to meet the current rapid development of mobile payment industry situation and broad prospects for development, which brings not only convenience to users from fixed-line payment to mobile payment, but also lets them experience the advantage of smart city constructing.This system integrates many technologies such as Java Web development technologies, Android development technology, network communication technology, encryption and digital signature technology and so on. By using J2 EE technology system, Smart C ity Server provides clients with a strong background support with integrating SSH open-source framework and conducting server data management by use of oracle database. The client implemented the function of mobile payment represented by Unionpay payment and Alipay payment by using Android development technology and invoking major payment plugin. By further studying on improving the security of mobile payment process, it raised effective solutions in the security of schemes, data, program and other aspects. It focused on the security of network data transmission based on the cryptographic algorithms and digital signature technology such as MD5, RSA. Moreover, it made a comprehensive testing on the entire mobile payment system through the use of relevant tools and methods, which ensured the stability and quality of the system.At last, the subject completed a mature and stable mobile payment system relatively. The design has been very good application and verification in the "smart city wireless gateway" project, which makes great practical significance on mobile payment services at home and abroad.
