2017 IEEE Region 10 Humanitarian Technology Conference (R10-HTC) 21 - 23 Dec 2017, Dhaka, Bangladesh 568 Design and Fabrication of a Password Protected Vehicle Security and Performance Monitoring System Safayet Khan ∗ , Obaidur Rahman † and Md. Ehsan ‡ Department of Mechanical Engineering, Bangladesh University of Engineering and Technology Dhaka, Bangladesh Email: ∗ ratulme12@gmail.com, † xionrahman.buet@gmail.com, ‡ ehsan@me.buet.ac.bd Abstract—Vehicle security has been one of the most pressing concerns for the last few years. There has been a number of researches to increase the security of the vehicle. This paper presents the design and fabrication process of a security system for vehicles using a password protected initiation. A simple portable hardware module has been made by assembling a liquid crystal display (LCD), a 4*4 matrix membrane keypad and a relay switch on a printed circuit board (PCB). The whole system works on an intricate algorithm implemented in an Arduino processor. The fuel injection in the engine of the vehicle is controlled by the relay added in the fuel line near the fuel pump and switches on only when the owner of the vehicle enters the correct password in the module. The module acts as an extra keylock for the engine in addition to the ignition key. Along with the security system, a cost-effective performance monitoring system is fabricated by using proximity switch which acts as a motion sensor and shows the speed of the vehicle at any instant in the display. The two projects has been crafted into a state of the art system which remains active even after the ignition key is bypassed. This significantly improves the security and surveillance concerns of the vehicle and in turn prevents any sort of theft or insecurities of the vehicle. This paper gives an optimum insight on the amount of work done on the project and presents an extensive view on the scope of betterment that can be done to this project. Keywords—Encrypted Initiation, Password Protection, Fuel Pump, Arduino, Proximity Switch, Vehicle Security, Vehicle Surveillance I. INTRODUCTION At present, vehicle thefts are increasing at a startling rate around the globe. Statistics on vehicle theft across various countries are shown in table [1].

The primary security system for a vehicle is its unique ignition key. Ignition key system uses unique key for every car and it is associated with a number of wires. By disconnecting the wires from the ignition key and through combination of certain set of wires a car can be started without being bothered about the unique ignition key. Thus safety of the automobile has become a vulnerable issue which created the urge of developing new security system. Security and performance monitoring system of a vehicle goes hand in hand. The most important component of a vehicle performance monitoring system is the speedometer. Tradi- tional speedometers are very expensive. Although the low- cost speedometers based on Infrared Radiation (IR) are very accurate but they are very vulnerable in nature. Any sort of disturbance in the path of radiation results in inaccuracy. This necessitated the fabrication of a cost-effective performance monitoring system. II. EXISTING SYSTEMS Most of the modern vehicles are entrenched with many anti- theft systems. Different systems like an Engine Control Unit (ECU) connected to the Info-Security Circuit Board and sen- sors inside the vehicle, in-vehicle engine immobilizer, smart card interface with vehicle [2], Global Positioning System (GPS) [3], Radio Frequency Identification (RFID) [4] used in Intelligent Computerized Anti-theft (ICAT) system, Real Time Biometrics based security system [1] and auto cop mechanism which is a video surveillance solution etc. has been developed till the date. All of these systems have different shortcomings. There is data timeliness and network delays, lack of secure processor and smart card chips, possible signal degradation, key malfunction and different natural factors like light, rainfall, fog and snowfall [5] acting as setbacks. Furthermore, these commercially available products are over-priced. Hence a comparatively inexpensive attempt to design and develop an efficacious vehicle theft control scheme using is done [6]. The conventional speedometers which are based on infrared radiation, Hall effect, rare earth magnet, encoder possess sim- ilar predicaments when it comes down to cost-effectiveness. The ones that are more effective cost higher and vice versa. So the fabrication of a cost-effective speedometer is done and integrated with the security system in a module for both security and surveillance of the vehicle [7]. The module is an embedded system for vehicles. It continuously stores all sort of data from the vehicle. The three major objectives are: • To ensure an encrypted starting system for a vehicle to strengthen the security • To monitor performance of the vehicle • To develop an attachable module for the vehicle to ensure above two objectives 978-1-5386-2175-2/17/$31.00 ©2017 IEEE
