The Design And Implementation Of Android Mobile Forensic System

With the rapid development of mobile Internet technologies and the rapid spread of mobile terminal devices,mobile terminals have become an indispensable tool for people today.Mobile terminals and networks are increasingly being used by criminal suspects.The use of smart mobile terminals to carry out activities such as fraud,illegal trade,spreading rumors,and spreading Trojans and other criminal activities and even terrorist attacks is increasing,giving social politics and economics It has caused serious harm and even jeopardized national security.The establishment of a scientific mobile digital forensics system and the development of effective mobile terminal forensics tools to provide technical support for combating illegal actions of mobile terminals have become an urgent problem for many judicial departments.This paper first describes the background of the mobile terminal forensics,the purpose and significance of the research,and studies the current situation and development trend of mobile terminal forensics at home and abroad.Then the basic knowledge and technology related to the system research are introduced in detail,including the background and architecture of the Android system,the architecture of MySQL and SQLite database,the basic concepts and principles of ROOT,the ADB command and the basic principles of forensics.The overall goal of system design was proposed,the entire system framework and functional modules were designed,and corresponding database design was made according to requirements.Completed the phone basic information forensics,WeChat database decryption and data analysis and storage,geo-positioning information analysis and visualization.Based on the mobile digital forensics specification,this article researches and designs a comprehensive forensic system based on Android mobile terminals from the perspectives of data acquisition,data analysis,and data presentation.Through rigorous tests and case studies,the results show that all functions of the system have achieved the expected results,and it satisfies the needs of judicial forensics personnel for mobile digital forensic tools.It has high practical significance and practical value.
