ARM 7 PROCESSOR BASED - BIOMETRIC

FINGERPRINT IDENTIFICATION WITH

ACCESS CONTROL SYSTEM

What is FingerPrint Recognition?

Finger print Recognition is the technology that verifies the

identity if a person based on the fact that every one has unique

finger prints. It is one of the most heavily used and actively

studied biometric technologies.

Advantages

Since fingerprints are the composition of protruding sweat

glands, everyone has unique fingerprints.

They do not change naturally.

Its reliability and stability is higher compared to the iris, voice,

and face recognition method.

Fingerprint recognition equipment is relatively low-priced

compared to other biometric system and R&D investments are

very robust in this field.

Disadvantages

Vulnerable to noise and distortion brought on by dirt and twists.

Some people may feel offended about placing their fingers on

the same place where many other people have continuously



touched.

Some people have damaged or eliminated fingerprints.

For companies where security is vital and access to certain

areas must be controlled and monitored, there should be an

access control system that allow companies to manage and

monitor all access points and locks, allowing for auditable

security and quick responses to any security breaches.

When we consider about Security the distinct ways are

Authentication, Authorization and Access Control.

Authentication is any process by which you verify that someone

is who they claim they are. This can be of any method of

demonstrating identity, such as a smart card, retina scan etc.

Authentication is equivalent to showing your drivers license at

the ticket counter at the airport.

Authorization is finding out if the person, once identified, is

permitted to have the resource. This is usually determined by

finding out if that person is a part of a particular group, if that

person has paid admission, or has a particular level of security

clearance. Authorization is equivalent to checking the guest list

at an exclusive party, or checking for your ticket when you go to

the opera.



Finally, access control is a much more general way of talking

about controlling access to a resource. Access can be granted or

denied based on the privillages granted to him. Access control is

analogous to locking the gate at closing time, or only letting

people onto the ride who are more than 48 inches tall - it's

controlling entrance by some arbitrary condition which may or

may not have anything to do with the attributes of the particular

visitor.

Here, in our project we have used an Biometric Finger Print

Sensor, Keypad and a PIC Micro controller (PIC16F877) for

authentication of a person. A computer that is connected to the

micro controller unit determines the authorization and Access

control rights.

All user access information is gathered by a central PC-

based workstation where the administrators can retrieve and

analyze the information. This also has a LCD Display that displays

the login Date time and the name of the person and a Relay

output for controlling the system.
