The Design And Implement Of Android Mobile Phone Analysis System

With the rapid development of the Internet and smartphone industry,smartphones have become essential for nearly everyone.Communication is a neccessary link in hunman society,nowadays the most important social media for people to transfer information become smartphones.They store a lot of information about the personal privacy,such as contacts,SMS,instant message,social softwares etc..Under the premise of legitimate access to these data,these data are conducive for the justice department to detect the case.So the mobile device forensics problem has been widespread concern.However,the foregin Android mobile phone forensics system is not localized enough for Chinese smartphones.In view of the above problems and practical needs,this paper presents an Android mobile phone forensics system for the basic information ande application software forensics.This paper first describes the background of the project and the status of digital forensics system,including the domestic and foreign development trend.Secondly,it introduces the background and architecure of Android,also the basic knowledge of the system development including SQLite,MySQL,data exchange format and common character encoding etc...Then,the overall goal of the system is put forward,and the structure and functon of the system are designed,the same as the databases.The system mainly includes two part:application forensics and original file analysis.Through the analysis of QQ,Baidu Map,GaoDe Map application data,users can quickly and accurately obtain the mobile phone contacts,group infomation,chat log,location and navi information etc..The moblie phone original data can be filtered by the file infomation,users can also search keyword through KMP algorithm,and even doing data statistics.it improves the efficiency of processsing and viewing the original data.After testing the system,all the features have achieved the desired effect including applications forensics and original data analysis.The system has good application value and application prospect.
