CHAPTER from, harm. It will applies to any






2.1       Introduction

This chapter which is Literature
review will explain the concept and theory of the project as a whole project.
In this chapter, it’s is the important part of the report project.

chapter will explain a detail about history of security, type of security,
history about biometric and type of biometrics. Since this project is related
with security and biometrics. This chapter also discusses about the previous
related works as well as a guidance and reference just to get an idea to
improve and idealized our project. In this process, the source of material was
gathered in the most of the literatures are from the related articles,
journals, Internet which is web surfing and also got the information from supervisors.
These literatures are then compiled and use as a guidance and reference to make
this research and complete of this project.



2.2.1 History about security

Security is the degree of resistance to, or protection from, harm. It
will applies to any range of people. As noted by the institute for security and
open methodologies (ISECOM), security provides “a form of protection where a
separation is created between the assets and the threat.” Security is very
important for the enterprises and organizations of all citizens and in all

2.2.2 Type of security

are many categories of security which is physical security, information
security, IT and computing security, identity management and access control,
procedural security and personnel security. In the research there are two
important type of security which is physical realm and IT and computing realm.

This project which is Fingerprint safety briefcase is basically on
physical security which describe a security measures that this project is
design to deny unauthorized access to facilities, equipment and resources, and
to protect personnel and property from damage or harm. The example of harm is
theft or terrorist attacks. Fingerprint safety briefcase can give a high
security and privacy to the owner and also can be used at many place
industries, offices and colleges or even at home. Security is very important
and especially in this competitive world, human cannot find ways to provide
security to their confidential belongings manually. Because of this problem,
personal identification technology, which can distinguish between registered
legitimate users and imposters, is now generating interest. 


2.2.3 History about biometric

Biometrics is very greater security and convenience
than traditional methods of personal recognition. In some applications,
biometrics can replace or supplement the existing technology. In others, it is
the only viable approach. One emerging technology that
is becoming more widespread in such organizations is biometrics is automatic
personal recognition based on physiological or behavioral characteristics.
However, this biometric is the accountable, responsible use of biometric
systems can in fact protect individual privacy.

System Using Microcontroller and LabView.



the case of study, Devendra Kumar Yadav, Sumit Singh, Prof. Shashank Pujari
(2015) developed student 1) Fingerprint Based Attendance System Using
Microcontroller and LabView by using 8051 microcontroller.  A fingerprint recognition system can be used
for both verification and identification. In verification, the system compares
an input fingerprint to the “enrolled” fingerprint of a specific user to
determine if they are from the same finger (1:1 match).



identification, the system compares an input fingerprint with the prints of all
enrolled users in the database to determine if the person is already known
under a duplicate or false identity (1:N match). Figure
2.1 shows the block diagram of the Microcontroller based attendance system.
This design combines the Microcontroller with the Fingerprint Module, display,
and communication interfaces. This integration accelerates development while
maintaining design flexibility and simplifies testing. Figure 2.1 shows the
block diagram top level system that used the same fingerprint device like our
project but in different purposed.

on this project, the project uses the same main input as the fingerprint safety
briefcase. The main input is biometric fingerprint sensor that the most
important sensor in our project. The functions of the biometric fingerprint
sensor is to scan the fingerprint pattern from the users and send it to PIC
microcontroller to process the input and identify either it a right user or
wrong user.




Biometric lock boxes



In this study, this project which is Biometric locks box is much related
with our project which is Fingerprint safety briefcase. The Biometric lock Box
uses the Adafruit Fingerprint Sensor as well as a numeric password or code and
a mechanical key-lock to provide triple-security. This project the main component is Arduino Uno and
fingerprint sensor



2.2 The circuit of biometric lock box

Based on this project use same input which is
fingerprint device but the different is the process of the input and output.
This biometric lock box using a Arduino Uno as a process of input and output by
giving the command. Next this project is made by box. The different between
this project and our project is the input. This biometric box is using a
password or code and mechanical key-lock to access the lock box. While our
project just using a fingerprint sensor to open the briefcase, if wrong access
fingerprint the briefcase will not open.

In the next
study, the project has been presented to show It provides high identification
performance, low power consumption, and can easily be integrated into a wide
number of applications such as a door lock system, safe box, simple access
controller, vehicle control, and ATM. This project will differ from other
devices out on the market due to our systems ability to be interfaced with a PC
via the USB cable. This feature will make setting up and securing the system
easy. An Atmega324 will be used to interface all of the components in our
system. The fingerprint scanner is controlled using RS-232 serial communication
so this device will be connected via its UART pins to the microcontroller
UART0. An FTDI serial-to-USB chip will be used to interface the microcontroller
to the PC again using the UART1 pins on the microcontroller. It appears that
interfacing the microcontroller with the PC will be the most challenging aspect
of our design.

In this study
this project uses Atmega324 in order to act as main system that controls all
the command. Next, this project design also use metal box to prove the
potential of security. The different between our projects are, we use wooden
briefcase as a prototype to show that everyone can use it everywhere at any
