Design And Implementation Of Mobile Deposit System For House Maintenance Funds

With the development of mobile networks and the popularization of mobile smart devices,especially the application of 5G networks,mobile payment has further become a payment method for the public.In order to realize the informationization,scientization and mobility of the deposit of house maintenance funds,in the context of the development of mobile payment,in view of the many inconveniences of the traditional deposit of house maintenance funds,the procedures for depositing house maintenance funds were further simplified and the deposits were broadened channels,improve deposit efficiency and transparency,combined with mobile payment,this paper studies and designs a mobile deposit system for house maintenance funds.This topic combines the construction goals and needs of the mobile deposit system project of house maintenance funds proposed by the competent department of a city,and conducts demand analysis,architecture design and detailed design of the mobile deposit system.Among them,the detailed design includes database design and key interface design,system security design,using MUI framework and HTML5+ to achieve system functions,and functional testing,performance testing and security testing of the system.In the system security design,in order to ensure data consistency and integrity,the correcting logic mechanism is studied.Considering how to effectively improve the security of the transaction data transmission process,the identity authentication technology and digital signature technology used in the system are studied in depth.In view of the security risks of dynamic response identity authentication technology,elliptic curve encryption technology and digital signature technology,improved and proposed a two-way challenge response dynamic password identity authentication technology and two-way challenge response elliptic curve encryption digital signature protocol,and made security analysis.The mobile deposit system for housing maintenance funds developed by this subject has been put into operation in a city.The successful application of the subject has made the deposit of house maintenance funds more convenient,improved the efficiency and experience of the citizens,and improved the public service level of the house maintenance fund business administration department.
