Design And Implementation Of Bank Internet Sub System Of Fund Sale Platform

Along with the development of FinTech,many fund management companies have begun to embrace the Internet development and established their own platform to sale funds online.Because of the online sales,these platforms are sure to link investors through bank systems.Whether to subscribe funds,or to make the redemption,these require the APIs provided by every bank.The bank internet system is born based on the increasing demand of online payment.The bank internet system is responsible for all the online trading operations,including connecting the bank's trading system and providing uniformed API that other inner subsystems can call.This paper discusses the functions the bank internet system should provide,such as protocol management,trading,bank reconciliation and trading safety.Protocol management means authentication of personal information,signing or rescinding a contract of individual's bank account.Trading refers to the subscribing or redemption instructions between bank account and mutual funds.Bank reconciliation is the procedure of checking transaction records.And the trading safety means the encryption of message using RSA technology during the communication process with bank.This paper first describes the background of this topic,and analysis the research results overseas,finally forms the main content of the whole topic.According to every specific business requirement,we decide the key techniques that will be used in this project.In this topic,we solve the problem of conflicting trade states,and use the RSA-SHA1 algorithm to prevent anyone tamper with the communication message.After analyzing the requirement,we planned 4 specific modules,designed class diagram and sequence chart for every module.And then,we performed every module according the results of designing process and draw the whole detailed flow-process diagram.At last,we tested every module and whole process in order to achieve the expectations.
