An efficient automotive security system is implemented for anti-theft using an embedded system integrated with Global Positioning System (GPS) and Global System for Mobile Communication (GSM). This proposed work is an attempt to design and develop a smart anti-theft system that uses GPS and GSM system to prevent theft and to determine the exact location of the vehicle. In case of an accident this system automatically sends the message for help to one's relatives. The preventive measures like engine ignition cutoff, fuel supply cutoff, electric shock system is also available. The owner can lock or unlock his/her vehicle with the help of SMS. This complete system is designed taking into consideration the low range vehicles to provide them extreme security. Tracking framework or system is getting to be progressively vital in expansive urban areas and it is more secured than different frameworks. The proposed work is cost-effective, reliable and has the function of preventing theft and providing accurate tracking system. A smart anti-theft system is one of the essential systems that homogenize both GPS and GSM systems. It is fundamental because of the huge numbers of uses of both GSM and GPS frameworks and the wide use of them by a great many individuals all through the world. Keywords: GPS, GSM, Arduino, Haversine Formula. 1. INTRODUCTION The anti-theft vehicle tracking system is a kind of developing a tool which protects your much essential needed thing in a person perspective to keep his/her vehicle. In this growing era of technology, we the humans are much intended to come up with new systems which enhance the future generation into a global system. The Global Positioning System (GPS) plays an important role in developing this tracking feature. It is so because of the enabling feature of locating an exact position of any kind of activity around the world, round the clock. GPS is a satellite-based navigation system which lets you depict the location of the vehicle. It makes you detect the exact position and helps in identifying a particular thing. This satellite-based navigation system communicates with the mobile application that is installed within the device. The device gets a notification regarding the position of the vehicle which makes easy to locate anywhere in the respective place. GSM (Global System for Mobile Communication) is a mobile-based technology which retrieves the location of the vehicle and sends a notification for the owners mobile. Both the GPS and GSM works
