Abstract— Due to the increasing
vehicle theft cases reported all over the world, vehicle security system has been a topic of great
interest over the years. There is an increase in the production of vehicle
every year, but at the same time, theft attempts for the vehicle is also
increasing. It has been shown in the statistics that, nearly 1500 vehicles have
been stolen between the years 2008 and 2012. Most of the advanced
vehicle security systems best suit the four wheelers. The security system
available in the market, for the two wheeler security, is of no use as the
thieves are well equipped. This paper “Vehicle Security Control” focuses on the
ignition of fuel in vehicle based on fingerprint . In this project, a reliable
design for vehicle security has been proposed
with features enhancing the control of fuel for ignition. The
fingerprint is detected and matched with the stored database. If the detected
fingerprint matches with the registered fingerprint, then the solenoid valve
gets opened and there is a fuel flow for ignition. This approach would be
fruitful to the users who want to possess valid and authenticated entry.
Keywords— Fingerprint sensor,
perfect security system is required for any vehicle as the theft rate is
increasing every year. There are many security systems available in market with
variety of functions, modes, etc, but they are costlier. At the same time,
those system are not suitable now-a-days, because thieves are well equipped. In this project, the latest technology called
biometric is used for vehicle’s security. Biometrics is the technical term which refers to metrics, related
to human characteristics.
The reason for going into
biometrics is that its chances of being duplicated are very less. The realistic
authentication for access control is the Biometric authentication. The
biometric identifiers refer to the physiological characteristics and
behavioural characteristics. Fingerprint, face recognition, DNA, palm print,
hand geometry, iris recognition, retina and odour/scent are called the
physiological characteristics of the biometric identifier. The pattern of behaviour of a person like
rhythm, gait and voice are called the behavioural characteristics. Fingerprint
sensor is more advantageous than the other biometric sensors. This is because
the fingerprint sensor provides high accuracy, high reliability, high stability
and high acceptance. Also, fingerprint sensors can be used both for
identification and authentication. And so in this project fingerprint sensor
has been chosen for providing security.
In this project, fingerprint
of the people can be used to make sure the authorized access of the vehicle.
The primary security system uses a combination of enrolled Fingerprint and the
vehicle key to enable the fuel ignition. It means that even if someone gets
hold of user’s key the vehicle is still safeguarded from the theft and misuse.
This system also has the feature of sending message to the owner of the vehicle
when unauthorized access has been detected.
In forensic applications automation of the
fingerprint recognition process turned out to be a great success. Fingerprints
have remarkable permanency and individuality over the time. The fingerprints
offer more secure and reliable person identification. The fingerprint sensor
takes in the fingerprint of the user which in turn sends the signal to the
microcontroller. The microcontroller then matches the fingerprint with the ones
that are stored in the database. Once the fingerprint is matched, the
microcontroller sends the signal to the solenoid valve which controls the fuel
flow for the ignition of fuel in the vehicle. At the same time ‘matched
fingerprint’ message will be displayed in the LCD. Whenever an unauthenticated
person tries to scan his fingerprint, there is no fuel flow for ignition, and
hence the vehicle is secured from starting. At the same time, ‘did not match’
message will be displayed in the LCD.
This paper focuses on the
fuel flow in vehicle using fingerprint sensor for generating the results along
with some proficiency and accuracy by reducing its cost factor. It could be
easily bought by customers at affordable price.
The security systems that
are availabe in the market are very expensive so that the buyers could not
afford to have a security system that is efficient. The security systems that are
affordable have lots of limitations. The basic security system that is
available in the market at affordable price is provided with just an alarm
circuit. It makes loud noise in such a way disturbing people around it whenever
someone touches the bike. Even if the owner touches it unfortunately, without turning
on the key, then also the system installed will produce loud noise. This
security system is simple in construction but at the same time it is not user
Numerous researches are being
carried out to improve the security system to the vehicle that is user friendly.
One such system has incorporated radio frequency identification method for
vehicle security. This system includes three units like transmitting unit,
receiving unit and the interfacing unit. The receiver unit is always embedded
in the vehicle and the transmitter unit is present in the hands of the owner.
So that the owner can control the vehicle through this transmitter unit. This
establishes a perfect communication between the vehicle and the owner. But this
has the limitation of operating range. This system is suitable only upto the
operating range of 200m.
The next level of security
system was introduced with password. Once the user forgets the password, then
it is difficult for the owner to start the vehicle. Then came the GSM based
security system. Since the microcontroller can be interfaced efficiently between
input and output devices, some security systems used microcontroller
interfacing. In such GSM based security systems, mobile phone has been used as
a medium of communication between the user and the system. In such systems the
mobile phones were used as the input device. This type of security system has
been used only for tracking the vehicle by making phone calls from the
registered SIM through the input device, mobile phone. This system does not
deactivate the engine operation and it also doesn’t inform the user regarding
the theft. It has been used only for tracking the vehicle. This GSM based
security system is bit costlier when compared to other type of security systems. There is an other type
of anti-theft alarm system, where the
number of sensors used are more and because of this the system became
complicated and costly.
III. PROPOSED SYSTEM:
system is designed in such a way that it is easily affordable for the buyers.
Though this system is affordable, it has very little limitations when it is
compared with the other systems.
Fig.1: Proposed block diagram
The supply to the components that are
used in this system is DC. Hence battery which supplies the DC voltage is used.
The battery used in this system can supply the voltage of 12 v. But, some
of the components used in the system
requires only 5v. Hence voltage regulator is used to regulate the supply
voltage. In order to have the ripple free supply voltage from the regulator,
the capacitor is used. The ripples have to be removed as it may damage the rest
of the components used. The ripple free supply is regulated using the regulator
IC. Then this voltage is given to the components like microcontroller and the
fingerprint sensor. The fingerprint sensor has the EEPROM chip which is used to
store the fingerprints for authorized access. The fingerprint sensor senses the
fingerprint of the user and then it is matched with the database of fingerprint
stored in its memory.
When the fingerprint matches with the
database then the microcontroller sends the signal to the solenoid valve. When
the solenoid valve receives the signal from the microcontroller, it starts
operating. If the fingerprint sensed by the fingerprint sensor doesn’t match
with the database then signal will not be sent to the solenoid valve. So the
solenoid valve doesn’t operate. It means that there is no fuel flow for the
ignition system. Hence the vehicle can be secured from the unauthorized person’s
access at the time of ignition itself.
IV. SYSTEM ARCHITECTURE:
A.FINGERPRINT SENSOR (R305):
fingerprint sensor is an electronic device used to capture a digital image of
the fingerprint pattern. The image that has been captured by the fingerprint
sensor is called a live scan. The biometric template is created by digitally
processing the live scan. This biometric template is used for storing and
matching. This fingerprint sensor module with TTL UART can be interfaced for
direct connections to microcontroller’s UART and to PC’s through MAX232 or
USB-Serial adapter. The user can store the finger print data in the module and
can configure it in 1:1 or 1: N mode for identifying the person. The
fingerprint module can be directly interfaced with microcontroller. A level
converter (like MAX232) is required for interfacing with PC serial port. This
module has the best image processing capability and can capture images upto the
resolution of 500dpi

B. SOLENOID VALVE:
Solenoid valve is an electromechanically
operated valve. The electric current flows through the solenoid and controls
the valve. There are different types of solenoid valve depending on the number
of ports. In two port valve the flow can be switched on or off, whereas in a
three-port valve, the flow is switched between the two outlet ports. The valve
can be placed together on a manifold if it is a multiple solenoid valve.
Fig.4 Solenoid Valve
They can operate at a voltage of about
12V. The mode of operation of such a type of valve is normally closed. The
working media can be air, water, oil, etc.
It has different response time with open timing of 0.15s and close
timing of 0.3s. It can operate at the
temperature of about -100C to 800C.
C. ARDUINO UNO:
The microcontroller board based on the
ATmega328 is the Arduino Uno. It has 16 digital input and output pins, out of
which 6 are provided for PWM output. It also has 6 analog inputs, a 16 MHz
quartz crystal, a USB connection, a power jack, an ICSP header and a reset
button. It can support the microcontroller in all the way.
Fig.5 Arduino UNO
Arduino has boot loader which is
pre-programmed so that it simplifies the uploading of program on the flash
memory. The operating voltage of such an
Arduino is 5V. The recommended voltage is around 7V to 12V. The DC current for
one I/O pin is 40mA. It has the flash memory of 32KB.
D. LIQUID CRYSTAL DISPLAY:
Liquid Crystal Displays (LCD) have
materials, which combine the properties of both liquids and crystals. The LCD has electrodes. When the required
voltage is applied to the electrodes, the liquid crystal molecules would align
themselves in the particular direction in such a way displaying the desired
character. 16×2 alpha-numeric lcd is used in this security system to display
the message of fingerprint match or fingerprint doesn’t match.
LIQUID CRYSTAL DISPLAY
The power supply to the
components used in the designed system is provided by the battery of 12v. The
power supply circuit also has a voltage regulator, because most of the
components used in the system require only 5v supply. And so, the voltage
regulator regulates the voltage from the 12v battery.
v. RESULT AND ANALYSIS:
system is capable of providing security to the vehicle. This designed security
system can be used in all the two wheelers that require protection against
theft. Fig.7 shows the hardware of the proposed system.
Fig.7 Proposed system
the fingerprint matches with the stored database then the ‘Found match’ message
will be displayed in the LCD.
Fig.8 Authorized fingerprint
the fingerprint doesn’t match with the fingerprint stored in the database then
‘did not match’ will be displayed in the LCD.
Fig.9 Unauthorized fingerprint
This vehicle security system was
designed to focus on ignition of vehicle by the means of fingerprint. The
reason for developing this model is to increase the security level and the
robustness of the vehicles from day-to-day threats. The main reason for using
this, it is low in cost and the fingerprint biometric which is used, it cannot
be matched of any two people. So it results in the accuracy for verifying the owner
of the vehicle who can only access their own vehicle. With significant improved
in range and reliable data accuracy in real time, this project promises a bright
future with a high commercial value.
VII. FUTURE SCOPE:
This paper has
many of the future scopes for developing very high security systems. The
proposed system can be extended by including GSM, GPS, accelerometer sensor and
pressure sensor. GSM module will help in sending SMS to the owner regarding the
unauthorized access of the vehicle, which act as safety measure for the vehicle
theft. GPS provides additional safety, that is, it helps in tracking the
location of the vehicle when it is being stolen. The accelerometer sensors are
helpful in knowing about the fuel theft whereas the pressure sensors can be
used for indicating the air pressure in the tubeless tyre of vehicles. We can
use this type of security system in car ignition also.
