Logical Im.ge Acquisition and Analysis of Android Sm.rtphones

引用

Journal of Com.uter and Com.unications 2024年第4期12卷 139-152页

作者： Nursel yalçın Tayfun yıldırım Departm.nt of Com.uter and Instructional Technologies Education Faculty of Education Gazi University Ankara T&#252rkiye Departm.nt of Com.uter Forensics Institute of Informatics Gazi University Ankara T&#252rkiye

Android sm.rtphones largely dom.nate the sm.rtphone m.rket. For this reason, it is very im.ortant to exam.ne these sm.rtphones in term. of digital forensics since they are often used as evidence in trials. It is possible to acquire a physical or logical im.ge of these devices. Acquiring physical and logical im.ges has advantages and disadvantages com.ared to each other. Creating the logical im.ge is done at the file system.level. Analysis can be m.de on this logical im.ge. Both logical im.ge acquisition and analysis of the im.ge can be done by software tools. In this study, the differences between logical im.ge and physical im.ge acquisition in Android sm.rtphones, their advantages and disadvantages com.ared to each other, the difficulties that m.y be encountered in obtaining physical im.ges, which type of im.ge contributes to obtaining m.re useful and effective data, which one should be preferred for different conditions, and the benefits of having root authority are discussed. The practice of getting the logical im.ge of the Android sm.rtphones and m.king an analysis on the im.ge is also included. Although root privileges are not required for logical im.ge acquisition, it has been observed that very lim.ted data will be obtained with the logical im.ge created without root privileges. Nevertheless, logical im.ge acquisition has advantages too against physical im.ge acquisition.
