Research And Implementation Of Collaborative Filtering Mobile Social Network Service

With the development of Internet and the increasing popularity of mobile terminals, mobile social network service (mobile SNS) has greatly developed and has become integral part of life. While we still face harassing phone calls and spam messages. Security Zone is that kind of application that we use to resolve harassing phone calls problems based on social network service. It takes full use of the feature of SNS and the concept of collaborative filtering. And it provides corresponding solutions to some issues for better use experience and services including user interfaces, building the the database of features. large scale concurrent access. Provide the users with a safe environment for intelligent terminal.Starting from overall design, this thesis specifically presents the information gathering, features selection, trust network building, software configuration module and so on. Security Zone realize collaborative filtering of harassing phone calls and spam messages and provide a safe social network service for the users. The user can automatically expand the database of features that they used and it provides users with new experience of touch-screen devices. Firstly, the thesis surveys and analyzes the development status of mobile security software and social network service. Secondly, demand analysis and runtime environment of the system are described. Thirdly, the design of system architecture is proposed based on demand analysis, and details of design solutions of the system are presented. After that, the implementation of main modules of the system and the storage solution is given.This thesis focuses on discussing the overall design of Security Zone system and implementation of some modules on the Windows Mobile platform and the support of large-scale simultaneous online users also the support for collaborative filtering of server-side architecture design and implementation. It introduces realistic meaning of mobile security software. Also, the user’s information management, Information security community for the use of collaborative filtering.Finally, through analyzing the result of the system test, the functions of the system is validated, and it is proven that the function and performance of the system meet the design requirements.In the end, the summary of the whole thesis, current shortcomings of the system and future work are given. Also, the summary of my work and research progress during master-degree study are described.
