VEHICLE ANTI-THEFT SYSTEM BASED ON AN EMBEDDED PLATFORM

Abstract

In modern day vehicles, vehicle anti-theft system i s of prime importance. The vehicle anti-theft syste m presented here consists of multiple layers of protection with one complementin g the other, rather than the conventional anti-thef t system where a particular system is only being used. The first layer of prote ction in the system is a Fingerprint recognition, b ased on which the doors are opened. The Fingerprint matching is done by utilizi ng the Minutiae based Fingerprint recognition schem e. Also to prevent thieves from breaking the glass and getting inside the vehi cle, vibration sensors are used in all the windows with a threshold level to prevent false alarms. Once inside, the vehicle is turned on only with the mechanical keys along with correct knumber entry on the combination keypad present, failing to do so for th ree successive times will result in vehicle getting immobilized by cutting the fuel supply and an alert message is sent to the mobile n umber of the owner. Further to prevent the seizure of the vehicle, Tyre pressure sensor is also being used which also alerts the own er through a mobile message. The seized vehicle can be tracked using a GPS tracker which is also being attached. The different layers of protection defined are controlled by an ARM 7 based controller acting as the central node. The whole system was tested using a test set up by mimicking the vehicle door, vehic le immobilizer etc. with equivalent motors whereas Fingerprint data was rece ived from Matlab based GUI application. The experim ental results proved the functionality of the anti-theft system in working e nvironment.
