Forensic analysis for IoT fitness trackers and its application


A fitness tracker monitors our daily activity by measuring distance walked (or run), calorie consumption, heartbeat and quality of sleep. Although originally designed to check the user’s health, its data is important in verifying the veracity of interrogation responses of the suspect, or the activities of the victim near the time of the incident. Xiaomi Mi Band 2 and Fitbit Alta HR are representative fitness trackers which allow users to view measured data on connected mobile devices. We compare the functionality of the two wearable devices, select the data that must be acquired (based on the Android device used), and provide the analysis methods for each file from the perspective of digital forensics.
