Preface

The System Requirements Specification is one of the critical documents since it identifies the aims and goals of the project. This is important to the success of the project since it clearly outlines what the development team must achieve in order to classify the project to be complete. A strict definition of this type also enables the project team to outline the necessary means to achieve these goals. If this step is not carried out correctly the project can encounter delays caused by changes to the requirements brought about by developers and customers, thus altering the project schedule.

1 Introduction

This is a System Requirements Specification for the Final Year project “Fingerprint Verification for Smartcards”, sponsored by Motorola. This Project is being conducted by the final year students in the Faculty of Information Technology at the University of South Australia in the year 1999.

This document aims to outline the requirements of the finished system as specified by the sponsors, namely Motorola, in meetings held during the initial phases of the project. While this document will be used as a starting point for the system design, it is by no means complete and exhaustive, and will be revised as the project continues over the time scale as projected by the project plan.

1.1 System Purpose

The purpose of this system is to produce an active demonstration of the use of fingerprints as a biometric where a template can be stored on a smartcard. And then a competitive analysis is performed on the fingerprint and compared to the template. This system uses a two-process security check. The first check is if the key (smartcard) is a valid card to enter the system. The second process is to compare a fingerprint with a fingerprint template encrypted on the smartcard. The fingerprint verification will ensure that the person with the card is the actual owner of the smartcard. This system will thus demonstrate an increase in security via an entry key, which can not be forgotten. The completed system will show that this method of using the fingerprint biometric is an enhancement, if not an alternative, to the methods of security currently in existence. If this project is successful in the demonstration of biometrics as a feasible method of security it could lead the way for other biometrics such as retinal scans and voice patterns to be used for a similar purpose. This is on the condition that the templates of the biometrics will be small enough to fit in the memory of a smartcard.

1.2 System Scope

Name: Fingerprint Verification for Smartcards

The system will aim to produce the following results:

1. Demonstrate that Fingerprint Verification can be used in conjunction with smartcards using a two-stage security check.

2. Test and benchmark the accuracy and efficiency of the fingerprint scanner.

3. Test the tolerances of the fingerprint scanner with regard to poor biometric scans such as with dirty fingers.

4. Produce a working real time demonstration of Fingerprint Verification in use with smartcards.

To achieve these goals the system will incorporate the following:

1. It will use the Biomouse plus connected to a PC.

2. It
