Vehicle Tracking System
Methods
1.Hood Lock
Cheap Method.
Protects the parts
under the hood.
Generally used in race
cars.
2.Steering-Wheel Lock
Least expensive
method.
Restricts access to
Steering-Wheel by
locking it in place.
3.Mechanical Immobilizer
Prevents access or
motion of vehicle.
Used in conjunction
with other methods.
Good against
amateurs.
4.VIN Etching
Unique VIN for each
vehicle.
Etched on all important
parts.
VIN etched parts help in
easy identification of stolen
cars.
5.Car Alarm
Most common method.
Most visually effective
device.
Makes a loud noise and
notifies everyone nearby.
Best used in combination
with a hood lock.
6.Kill Switch
Shuts down engine’s electrical
system when activated.
Usually hidden from burglars
view.
Sometimes deactivated by a
series of actions rather than a
switch.
7.Vehicle Tracking System
Most expensive and most
effective method.
Activated when a theft is
reported.
Stolen vehicle position tracked
using GPS.
Inbuilt in Audi, GM,
Volkswagen etc.
Introduction Fingerprint which go into deciding your genetic
make-up has a unique design.
A Fingerprint scanner reads the pattern of ridges
and valleys on fingers.
A fingerprint scanner is to discriminate someone in
both crime investigation and security.
Fingerprint Recognition
Optical Scannero Optical scanning is way to get a image of
a finger and to determine whether the
pattern of ridges and valleys.
o Optical scanning and capacitance
scanning is a charge coupled device
(CCD) ; it is simply an array of light-
sensitive diodes.
Fingerprint Recognition
Capacitance Scannero A simple capacitive sensor is made up of
one or more semiconductor chips
containing an array of tiny cells ; tiny cells
include two conductor plates.
o To scan the finger shorts each amplifier’s
input and output to balance the integrator
circuit.
Fingerprint Recognition
Working• Conductor plates, insulating layer and
finger surface acts as a capacitor.
• Capacitor in a cell under a ridge has
greater capacitance than under a valley.
• This difference is converted to voltages.
• The scanner processor reads this voltage
to determine whether it’s a ridge or a valley.
• By combining the data from each cell an
overall picture of the fingerprint is obtained.
Fingerprint Recognition
Analysiso Minutiae - concentrate on points where ridge lines end or
where one ridge splits into two (bifurcations).
o The scanner system software uses highly complex
algorithms to recognize and to measure the relative
positions of minutiae.
Fingerprint Recognition
Advantages Physical attributes are much harder to fake than identity cards.
You can't guess a fingerprint pattern like you can guess a password.
You can't misplace your fingerprints, like you can misplace an
access card.
Small storage space required for the biometric template, reducing
the size of the database memory required.
Fingerprint Recognition
Disadvantages Optical scanners can be fooled by pictures.
Capacitive scanner are vulnerable to finger shaped
mold.
Cut off the owner’s finger in a worst-case scenario.
If fingerprint is stolen, it is irreplaceable and cannot be
used again, unlike Passwords.
Fingerprint Recognition
CVKP-BG04 Made by Chinavasion.
A complete system that has
A fingerprint ignition lock,
Dual band GSM (900/1800)
messaging system, and
Standard car alarm system.
Sends a text message alert instantly in
case of forced entry.
Fingerprint Recognition
Fingerprint Recognition
Text commands can be send to disable
certain functions (like cut-off fuel supply)
or receive status message (in motion or
parked).
Fingerprint scanner can be installed in any
location, even hidden from common view.
Sensitivity can be adjusted in case of bad
weather conditions.
Fingerprint authentication in conjunction with other factors can
help in reducing auto theft. Fingerprint authentication comes
under biometrics and is a way fingerprints are compared and
matched. Fingerprint authentication has many uses as in
security purposes.
The process is simple, as in put your finger down. Trusted, as
in had stood the test of time. Fingerprints have been used for
identification for over 100 years. They are the standard without
question. In addition to signatures, fingerprints are the only
other form of identification that have legal standing in our
country.
