Android-Based Audio Video Navigation System Forensics: A Case Study

Vehicle digital forensics includes the process of collecting and analysing data stored in vehicles to find evidence related traffic accidents or crime scenes. Through this process, we can reconstruct events by recognizing various information such as driver behaviour, driving patterns, vehicle destinations, smartphones connected a vehicle. Recently, many forensic studies have been conducted, but few them dealt with Android-based infotainment (or audio video navigation, AVN) systems. While AVN systems adopt Android operating system, is not easy. This because support storage devices formats sources, making consistent collection analysis difficult. In article, perform on four systems: two 4.2.2 Jellybean-based 4.4.2 KitKat-based, aiming develop acquisition method appropriate for each version. As system forensics, logical performed physical KitKat-based For collected data, identify analyse Bluetooth navigation logs individually. Next, investigate differences structure file location major artefacts depending versions show limitations individual analysis. Finally, construct timeline driver’s activities integrating diverse which consist logs.
