Abstract- This project is set to overcome the
drawbacks faced by the users in the computer laboratories. Normally in computer
laboratory, if a user wants to access the computer he/she has to make his/her
entry in the lab logbook which is paper based. This consumes a lot of time for
the users to access the computer .Also, in this type of practice anyone can
access the computer without making his/her entry in lab logbook, which is
unsecure. And the laboratory in-charge cannot be able to maintain the entries
for a long time since it is paper based. The proposed project is set to
automate laboratories with the help of biometric fingerprint sensor to turn ON
the computer and also their entry will be recorded in the database. The module
consists of biometric fingerprint sensor, LCD display, Arduino uno and relay.
In this project, fingerprints of all users are first recorded in the database
of fingerprint module. When a user enters the laboratory he/she has to place
his/her fingerprint in the biometric fingerprint sensor if he/she is a
registered user then automatically a particular computer will be allotted and
it will be turned ON and their entry is recorded. If the user is non-registered
then none of computers will be allotted. The user can turn OFF the computer
either manually or the user can place his/her fingerprint. After the departure
of the user that computer will be free for the next user.

Introduction

Fingerprint is a unique identification pattern for
humans, which consist of a pattern of ridges on the finger that helps to grip
things by hand. Fingerprint scanner is the heart of this automated
authentication system which is responsible for the acquisition of images. Based
on the pattern of ridges and valleys of human fingers it can be recognized and
matched with the pre-stored patterns. It consists of sensors that are optical,
ultrasonic, thermal, capacitive, etc., but mostly optical and capacitance
scanning methods are used. In this project, a fingerprint module is interfaced
to a microcontroller with a serial interfacing, and this project uses a relay,
an LCD. This type of authentication for controlling devices and appliances is
highly secured and more reliable at a lower cost due to inexpensive
microcontroller. This can also be implemented as the main registration system
for computer centers in colleges and offices by adding external memory. The working
of this project involves three stages which are mainly registering the user
followed by the user authentication and finally turning ON the computer for the
registered user. The drawbacks of the previous system are mainly the time consumed
while the user registers and also time taken for turning on the system. The
feasibility of the project comes right from the authentication procedure which
guarantees secured access and also it prevents any confusion regarding which
user occupied a particular system. By the help of secured access we can be able
to curb all the drawbacks of the present system. It helps in numerous ways like
reducing time consumption and also decreasing the work done in registering
every time while entering the laboratory. The processing of this project
commences from the registration followed by the control send by the controller
to the pc displaying the user entry and also it is the job of the controller to
turn on relays for the turning ON the systems. The registration of the user
will be done with the help of fingerprint module and done only once for the
user. Hence with the entry of the authenticated user the system is allocated to
the user and also the PC is turned ON for the usage.

Literature Review

“Fingerprint Based Attendance System Using Microcontroller
and LabView”  by Devendra Kumar Yadav ,
Sumit Singh, Prof. Shashank Pujari, Pragyan Mishra UG Student, Dept. of ECE,
Sambalpur University Institute of Information Technology, Odisha, India which
had the concept of fingerprint based attendance system which helped in enabling
the knowledge of registering and counting user entry.

“Fingerprint Recognition Using Level 3 Feature Extraction
Method” by Chandra Prakash Singh , Susheel Jain , Anurag Jain M.Tech., RITS
Bhopal/ RGPV Bhopal, India which depicted various methods by which the
fingerprint gets stored and how it is been carried over the entire process.This
paper explains deeply about the various algorithms involved in the creation of
the fingerprint image and the process of collecting information from it.

“Fingerprint
Based Attendance Management System with SMS Alert to Parents” by  Sopan D. Borale , Poonam G.Chaudhari,Vaijanti
B. Patil ,Apurva ,D.Shingne.This project also stated about the creation of an
attendance based system and also involved some other concepts like the sending
of messages through GSM which gave some additional information but not
necessary for our project.
