SIMULATION OF FINGERPRINT AS A MEANS OF SECURITY

ABSTRACT

This project work is based on the simulation of fingerprints based biometrics, h is an application that allows the computer to be able to identify and confirm an employee in an organisation and to change from the old manual system of identification to the new system. Visual Basic 6.0 was used for developing the system because it is flexible and memory conserving. And to itself documentation, it is easy to understand and to overcome difficult tasks when compared with other languages. Microsoft Access 2002 is used for the database development and preferred query language is Structured Query Language (SQL) for record manipulation.

CHAPTER ONE

GENERAL INTRODUCTION

1.1     INTRODUCTION

When we interact with others we are used to identifying them by their physical appearance their voice or other sensory data. When we need proof of identity beyond physical appearance we obtain a signature or we look at a photo identification card. In cyberspace, where people need to interact with digital systems or with one another remotely, we do not have these tried and true means of identification available.

In almost all cases we cannot see, hear or obtain a signature from the person with whom we are interacting. Biometrics, the measurement of unique physical characteristics, is an ideal solution to the problem of identification. Biometrics makes it possible to identify ourselves to digital systems and through these systems identify ourselves to others in cyberspace. With biometrics we create a digital personal that make our transactions and interactions in cyberspace convenient and secure. Of all the biometrics available including face, ins and retina scanning voice identification and others, the fingerprint is one of the most convenient and foolproof.

Fingerprints have been used for centuries for identification and we have a substantial body of real world data upon which to base our claim of the uniqueness of fingerprints. It is scanning for instance is an entirely new science for which there is little or no real world data.

1.2     STATEMENT OF THE PROBLEM

The mostly used technology in electronic verification and identification is the use of Personal Identification Number (PIN). This technique is almost illicit in this modern day of hacking and cracking and is associated with the following problems; complexities, redundancy, slow accessing speed, insecurity and resource consuming.

It is even better stating the problem from the point of application of PIN authentication system, many organizations did not even posses the simplex PIN authentication system as part of their security measures. This is the causes of crime and fake identity presentation in many cases; could be among staff in an organization, by intruders, among fake students in an institution, etc.

1.3     AIM AND OBJECTIVES OF THE STUDY

The aim of this project is to implement a fingerprint biometric system that verifies and identifies a user to the security system based on an individual enrollment in the database. The objectives of this project are:

1. To develop a security system that secures a company’s information and a system that cannot be by passed or accessed by unauthorization use.
2. To develop a computer application that can improve security in an organization using a fingerprint identification method
3. To effectively use a biometric application fraud detection, fraud prevention and deny access to system intruders.
4. To use a biometric fingerprint identification method to preserve privacy of system users in a particular organizational setting.
5. To develop a system that will be reliable and time saving in terms of user authentication and identity verification.
6. To develop a computer application with ease of operation with well defined user interface that make ease for data verification.

1.4     SIGNIFICANCE OF THE STUDY

Biometrics method of identification is preferred over traditional methods involving passwords and PIN numbers for its accuracy and case sensitiveness. A biometric system is essentially a pattern recognition system which makes a personal identification by determining the authenticity of a specific physiological or behavioral characteristic possessed by the user. An important issue in designing a practical system is to determine how an individual is identified. Every medium of authentication has its own advantages and shortcomings. With the increased use of computers as vehicles of information technology, it is necessary to restrict unauthorized access to or fraudulent use of sensitive/personal data. Biometric techniques being potentially able to augment this restriction are enjoying a renewed interest.

1.5     SCOPE AND LIMITATION

The area of interest of this study will focus on fingerprint biometrics. The scope of this project will also be a database driven application where employee’s information will be protected by the front-end biometrics application. The application will be able to add new user, edit user’s information, update employee’s record and also verify each fingerprints.

1.6       DEFINITION OF TERMS

Integrity: To verify that a message or document is genuine and has not been manipulated or changed since its original creation and singing.

Authentication: To verify the identity of an individual or organisation sending the message.

Non-Repudiation: To ensure that the originator of the message or transaction cannot subsequently disown it.

Enrollment: The initial process of collecting biometric data from a user and then storing it in a template for later comparison.

Template: A mathematical representation of biometric data. A template can vary in size from 96bytes for hand geometry to several thousand bytes for facial recognition.

Identification: The process by which the biometric system identifies a person by performing a one-to-many search against the entire enrolled population.

Verification: Authentication process by which the biometric system matches as captured biometric against the person’s stored template.

False-Acceptance Rate (FAR): The percentage of incorrectly matched to a valid user’s biometric.

False-Rejection Rate (FRR): The percentage of inconsistently rejected valid users.
