Brain fingerprinting is a technique that measures recognition of familiar stimuli by measuring electrical brain wave responses to words, phrases, or pictures that are presented on a computer screen. Brain fingerprinting was invented by Dr. B. S. Farwell. The theory is that the suspect's reaction to the details of an event or activity will reflect if the suspect had prior knowledge of the event or activity. This test uses the Memory and Encoding Related Multifaceted Electroencephalographic Response to detect familiarity reaction. It is hoped it might be more accurate than a polygraph (lie-detector) test, which measures physiological signals such as heart rate, sweating, and blood pressure.
The person to be tested wears a special headband with electronic sensors that measure the EEG from several locations on the scalp. In order to calibrate the brain fingerprinting system, the testee is first presented with a series of irrelevant stimuli, words, and pictures, and then a series of relevant stimuli, words, and pictures. The testee's brain response to these two different types of stimuli allow the testor to determine if the measured brain responses to test stimuli, called probes, are more similar to the relevant or irrelevant responses.

INTRODUCTION
Brain Fingerprinting is a new computer-based technology to identify the person of a crime accurately
Brain Fingerprinting is based on the principle that the brain is central to all human acts.
Brain fingerprinting was invented by Lawrence Farwell which is used to detect the crimes based up on the brain wave responses
Why Brain finger printing?
In a criminal act, there may or may not be many kinds of peripheral evidence, but the brain is always there, planning, executing, and recording the crime.
As it can be applicable to determine the fundamental difference between a crime attempted person and a falsely accused.
This theory means that the brain processes known,
relevant information differently from the way it
processes unknown or irrelevant information.
The specific pattern EEG(electroencephalograph)
used in this technique is to process the known
information of a crime attempted person
Later Farwell discovered the MERMER ,
which
includes the P300 and additional features and is
reported to provide a higher level of accuracy than the
P300 alone.
MERMER Methodology:
Global Positioning System (G.P.S) using satellites can provide positioning information and proves to be a versatile all-time.
The models for GPS also include aiding sensors, e.g. dead reckoning, radar and camera.
An accurate steering control is obtained using Pulse Code Modulation technique
Interaction with Environment
The vehicle is required to withhandle its environmental capabilities with its intelligent controls.
basic driving functions consists of lane-keeping, safe distance maintenance, timely lane changing and overtaking.
WADGPS concept
The Master Control Station (MCS) receives the positioning information from the satellite by employing this concept.
The MCS is linked to GPS instrumented position location systems (PLS) installed on the autonomous vehicles through a data link sub system (DLS). The DLS can either use VHF or UHF or L-band, incorporating time division multiple access protocol to handle on the roads.
Dead reckoning performance
Once the vehicle commences the journey the sensors continuously keep track of the direction and displacement of the vehicle .
The desired destination and starting position of the vehicle together with the time of travel.
Digital road maps
The new generation microprocessors promises further increase in system capabilities.
The digital road maps, available on CD-ROMâ„¢s have substantially increased safety of automobiles.
ADVANTAGES
When traffic slows down vehicle speed is altered using moderate braking to maintain a constant distance between his and other cars.
In advanced systems just in the case the driver over speeds or suddenly falls over and guides the car to a safe halt. And if you have programmed it right, the GPS in the car would take you to your destination .
If a smart thief has managed to break in through the car, the car doesn™t start up even if it does the computer I the car would lock the steering wheel and cutoff the fuel injection supply ¦ in the mean time a signal is set to the nearest police station and the owner informing them about the thief.
Some designs now include so-called "pre-safe" systems, which sense possible collisions in advance based on emergency braking, skidding, and sudden evasive maneuvers.
CONCLUSION Making the autonomous easy to operate for the user and the designers should concentrate more in producing autonomous cars.
Due to speed control technique, accident free driving is possible and fuel savage is also made possible by the technique.
So that we could find ourselves using these autonomous cars in the near feature.
