INTRODUCTION
 Biometric consists of two words 'bio' means life and
metrics which means 'metrikos'.
 Biometric-security is used for the purpose of
identification and verification of individual.
 For the purpose of identification different biological
traits are considered.

Implementation of Biometric Security
 Biometric-security can be implemented in any device by
installing the software and providing scanner as an
additional hardware to provide input device.
 Then comparison between provided input and store data
takes places on the basis of that locking and unlocking
depends.

Steps involved in investigation
The investigation process of biometric- fingerprint scanner
depends on three stages such as:
 Image enhancement
 Minutiae extraction
 Minutiae matching

Image Enhancement
Under this methodology image is capture and processed
through algorithm. Stages of algorithm are mentioned
below.
 Normalization
 Local orientation estimation
 Local frequency estimation
 Region mask identification
 Filtering

Minutiae extraction & matching
 The process of minutiae extraction convert image into
binary formate and then compare with other adjacent
pixels in order to produce considerable output image.
 In the process of minutiae matching comparison of
image takes place between the image in database and
input one.

Types of fingerprint scanner
They are described on the basis of technologies and
properties such as mentioned below:
 USB fingerprint devices: They can be attached through
USB port and available at cost of 77.77 pound.
 Keyboard fingerprint devices: They are attached with
keyboard and provide security to user. They are
available at price of 124.40 pound.

Cont....
 Fingerprint scanner and card reader: they are provided in
the combination of scanner and card reader at the price
of 31.03 pound.
 Car fingerprint scanner: This is considered as new
feature of auto mobiles and available at the price of
27686120.00 pounds.

Reviews of device
 USB Fingerprint Device: On the basis of users review.
This device is useful for individual as well as businesses
for security purpose. As they are provided with USB so
they provide easy installation interface to users. And
also provided at considerable price.
 Keyboard Fingerprint Device: On the basis of users
review. This reduces the chances of data lost and stole
from individuals device.

Cont...
 Fingerprint Scanner and card reader: On the basis of
users review the price of product is affordable along
with this it is portable and mobile.
 Car Fingerprint Scanner: On the basis of users review
this decreases the chances of car stolen and also give
ride of carrying keys.

Steps involved in face recognition system
identification process:
In order to recognition face using biometric-security devices
following process. Under this input is provided in the form
of image which is being capture by any scanner that is
present into device through this image is stored for face
detection.

Cont...
On the basis of that training and evaluation of image
take place. If result generated by detection process
and image stored into database both are same then
only unlocking process of device takes place.
