This document summarizes a mobile anti-theft system called Phone Guard. It aims to securely connect stolen mobile devices to their owners, notify owners of theft, and allow owners to remotely lock, wipe or track stolen devices. The system uses inertial sensing data rather than dedicated hardware to detect theft in real time. It identifies normal user behavior patterns with a Markov model and alarms when deviations occur. Key features include simulating device shutdown and airplane mode to allow tracking a powered-off device. The system will be implemented on Android using tools like Android Studios, Firebase and Figma. It has modules for login, finding devices, and anti-theft controls like fake shutdown and airplane mode switches.

3. ABSTRACT
• Mobile devices are valuable and portable items that are often targeted by
thieves.
• Existing solutions either rely on dedicated hardware or provide limited
functions.
• we propose a novel mobile anti-theft system that uses only the inertial
sensing data from the device to detect thefts in real time. The system
identifies the user’s behavior by segmenting and analyzing the motions
during the take-out action.
• The system then tracks the user’s habit using a Markov model and alarms
when the tracked data deviate from the normal pattern. We implement the
system on Android and evaluate its performance in various scenarios.
• The results show that the system is accurate, robust, and user-friendly.

4. Objectives
• To establish a secure connection between the mobile device and the
owner or authorized user.
• To enable the mobile device to notify the owner or authorized user in
case of theft or unauthorized access.
• To facilitate the locking, wiping, or tracking of the mobile device
remotely by the owner or authorized user.
• To locate and recover the mobile device if possible, or prevent the
misuse of the data stored on it.

5. Existing System
• Find My Phone (Google)
• Find My iPhone (Apple)
"Drawback's tracking functionality is contingent upon
the active status of your phone; if it is switched off,
the app will be unable to monitor its location."

• This application incorporates a simulated shutdown feature,
providing the appearance of a powered-off state while actively
running in the background.
• This application offers a simulated airplane mode functionality,
wherein the feature emulates the activation of airplane mode on
your phone. However, in actuality, the device remains operational
within the network.
• This application is designed for real-time location tracking.
