ABSTRACT

The fingerprint door lock system is proposed to solve confidentiality and security issue. The keys and padlock would have solved the issues of access control but the world at large has overgrown such method because it can be easily manipulated and does not guarantee personal security. Biometrics is the most secured and convenient authentication tool. It cannot be borrowed, stolen, or forgotten and forging one is practically impossible. This project the design and construction of fingerprint door lock system using Arduino UNO R3 board is divided into hardware and software section. The hardware components includes; R307 fingerprint module, LMO16L LCD, 12V, 1.1A solenoid lock, TIP 122 transistor, batteries and Arduino. The respective components was housed by a plastic casing with dimension of 55.88 mm height and 152.4 mm length. At the end of the design, an accuracy test was performed to observe the security level of the fingerprint scanner in which, it was discovered that the left thumbprint is the most accurate with 70%, followed by the right thumbprint, right index finger and left index finger with the accuracy of 61.2%, 41.4% and 30% respectively. The false acceptance rate (FAR) test was carried out in which 0% was wrongly granted access and also the false rejection rate (FRR) test was carried out in which 20% was rejected due to wet skin. The primary objectives of the project were achieved and the design functioned as expected. Hence, this project is reliable as it could increase the security level of door access system by implementing simple approach as Arduino.

CHAPTER ONE

INTRODUCTION

1.1     Background of the Study

 It has been noted over the years that, the general trend of human nature has always been longing for security physically, mentally and socially. It is no longer news that there has been recorded tremendous increase in the crime rate everywhere in the world. This issue is turning more severe every day (https://bestengineeringprojects.com/Arduino-fingerprint-sensor-lock/). To get away with this problem, there is need to take help from technology; these leads to this project “The design & Construction of a Fingerprint Door Lock System Using Arduino Uno R3 Board”. We know the saying very well- ‘Prevention is better than cure’, rather than to face the loss it is much better to take necessary actions to eradicate that issue before it happens.

However, it is prerequisite to note that some decades ago, when security was less of a concern in the society, our forefathers comfortably used simple sleeping mats to cover the doors of their huts. They were not bothered at all by any event of a burglary attack because they had a system that wouldn’t allow that to happen. Everyone knew their neighbours and virtually everyone else in the village. Nowadays it has become almost impossible to achieve that kind of sanity and therefore various tools have been employed over the years to safeguard the lives and properties of its owners Tamunowari, (2018).

Security describes protection of life and property. There are doors to keep people out, Key locks and chains reinforce the mode of security. Doors are being made of metals not just wood anymore. Influential persons in our society have bullet proof doors to ensure a good measure of security of self and family Ushie James Ogri, Donatus Enang Bassey Okwong, Akaiso Etim, (2015). The security sector is experiencing diversification as it has never seen before. This has brought about the need to review the reliability of already existing systems and look into the possibility of creating better systems that are smarter and more secure Ushie, et al, (2015).

The present electronic security systems we now enjoy have unequivocally been around for a very long time, although it has gone through a series of evolutionary changes to cater for the needs and security concerns of the present generation Tamunowari, (2018).

From using sticks to wedge doors to using mechanical locks, security systems have metamorphosed into using electronic equipment such as the microcontrollers which is intended to be used for this project to achieve a satisfactory security system Tamunowari, (2018).

Due to the drawback of other various form of door lock system; these nurture the needs for the design of a digital door lock system. Hence, this project work caption “The Design & Construction of a Fingerprint Door Lock System Using Arduino Uno R3 Board” presented here is an access control system which basically allows only authorized persons to access a restricted area; this system is best suitable for corporate offices, and home security.

Fingerprint System based access control is more secured as compared to the conventional swipe card or ID cards because of the exclusive fingerprint for every entity. Fingerprint Security Systems have fascinated people for centuries. They have been used as a method of personal identification since ancient times.

1.2     Statement of the Problem

Through observation, one could attest to the fact that the metallic keys used to access mechanical door locks are very susceptible to getting lost, which would mean breaking the locks over and over again if there are more occurrences of such scenarios, moreover, such access keys can be duplicated by unauthorized users. Also, another drawback of other electronic doors is complicated programming; Since most of control access system nowadays uses PIC, many engineers will face difficulties if problem occur on the device. The reason is that PIC is not an open-source IDE compared to Arduino. Therefore if problem occur, more time is needed for the engineers to create new coding for the device. Hence, there is need for the design of other form of an electronic door lock which will counteract the damning consequences of such repugnant occurrences.


1.3     Aims & Objectives

1.3.1    Aims

The primary aim of this project “The design & Construction of a Fingerprint Door Lock System Using Arduino Uno R3 Board” is to construct a device that utilizes fingerprint recognition technology to allow access.  This device is expected to eliminate the use of mechanical/metallic keys, prevent events of key misplacements, avoid excessive key duplication for everyone in the house and make the apartment where it is installed more difficult to break into.

1.3.2  Objectives

The objective of this project in its simplest terms is to replace metallic keys by building a fully featured fingerprint enabled electronic security system prototype. Below are the various outlined objectives.

1.     To create a door access system using Arduino approach.

2.     To test the accuracy of this device

3.     To review similar works on electronic door access key

4.     To understand the hardware and software design.

5.     To construction & package of the various components of the system.

1.4        Significance of the Study

The study is of great importance not just to broaden the knowledge of the students but to the society at large. Outlined below are the reasons why this project is of great importance. 

1.     Control: In a company building, one can control and restrict who goes into what part of the building. Additionally, residents and landlords of apartments and flats can control who can enter their room and it reduces the risk of anything getting stolen.  

2.     Fingerprint based security system is most secured system as compared to other systems. Reason is that RFID card or Keys of lock can be stolen, password may be leaked. However thumbnail of every human being is unique, so lock will not open unless the same person is present to give the impression of fingerprint.

3.     No need to carry the keys to open the lock. Or even there is no need to remember the password or any Pin number.

4.     Scientific research and studies have proved that fingerprints do not change as you grow up.

5.     Using Fingerprint saves time to gain access as compared to other methods

1.5        Scope of the Study

This project would only feature a fingerprint-based electronic door access system. In other words, it incorporates the fingerprint sensor and LCD. Other more advanced security features such as bursar, iris scanner or a facial recognition camera would not be incorporated to this design. For simplicity, this project will help in understanding about door access system, biometric fingerprint scanner and to study about Arduino and its application.
