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.
