ABSTRACT:
Security has
always been a major concern for the households and the office environment, and
for this concern various approaches are in place to address the problem. Most
of the major door lock security systems have several loopholes which could be
broken down to gain access to the desired places, and it creates a concern for
a secure lifestyle and proper working environment. Additionally, terrorism and
unauthorized access to places have become a major issue now-a-days, and there
is a need for a secure system to prevent unauthorized access especially in
shared access environment. With this consideration, a design and prototype of a
biometric fingerprint based door lock system has been presented in this paper.
Biometric systems such as fingerprint provide tools to enforce reliable logs of
system transactions and protect an individual’s right to privacy. The RFID or
password based door lock mechanisms can easily be compromised when the RFID
card or passwords are shared or stolen, thus for facilities with shared access
require biometricbased secure system. In the proposed system, fingerprints of
the authorized users are enrolled and verified to provide access to a facility
that is used by multiple users. A user can also be removed and a new user can
be enrolled in the system. We have implemented a centralized control system
from where we can control who can enter in which rooms and who cannot. This is
an Arduino UNO device based flexible working device that provides physical
security using the fingerprint sensor technology.
