Logical acquisition method based on data migration for Android mobile devices

摘要

Android dominates the mobile operating system market. The data acquisition method of Android devices has been the focus of research on mobile forensics technology. However, due to the continuous updates of the Android system version and the deployment of security technologies, existing data acquisition methods are limited and difficult to apply to new Android mobile devices. In order to address this problem, we propose a logical acquisition method based on system-level data migration services provided by Android mobile device manufacturers. The experimental result demonstrates that, for unrooted Android mobile devices, the proposed method is superior to existing logical forensic methods in terms of data acquisition capability.
