1. Introduction

1.1. Purpose

The purpose of this document is to present a detailed description of the Attendance Management

System Using Fingerprint. This document will fully describe all the functional and nonfunctional

requirements, design constraints, and other factors necessary to provide a complete and

comprehensive description of the requirements for the Attendance Management System Using

Fingerprint. It will also describe the external behavior of the Attendance Management System

using fingerprint.

1.2. Scope of Project

This software system will be the attendance Management System for Bahir Dar University,

Institute of Technology. This system will be designed to facilitate the attendance system of

students at dormitory level by providing tools to assist in automating the manual attendance

system.

More specifically, this system is designed to allow the head of proctors to manage and control

by taking the students fingerprint for collecting their daily attendance.

A variety of reports can be produced to give the information for student Dean’s for its needs in

the following format:

• Attendance Report

• Leave Report

• Absence Report

• Exception Report

2. General Description of Product

2.1 Context of product

This product is used in Bahir Dar University, Institute of Technology to provide some

kind of interaction between the proctors and the students. The product would be

responsible for taking the attendance and store it in an embedded database using the

fingerprint device of the proctor’s computer. It requires the students put their finger on

the fingerprint device.

2.2 Product function The product has a lot of benefits including:

1- Saving the time needed to take the attendance manually by calling the names of the

students.

2- It keeps the sleep time safety of the students for waiting the proctor to give

attendance.

3- It helps the proctor to prepare reports and process their data easily.

2.3 User Characteristics The users of the product are the proctors. The proctors should have a desktop computer

and should have the basic skills to deal with it.

Technical Expertise: Should be comfortable in using general-purpose applications on a

computer.

The proctor should train the students how to use the device properly. And the proctor is

responsible for any misuse of the device. The product may be used in every day at night

time.

2.4 Constraints The response time of the product is depending on the fingerprint machine which is

connected to the computer.

The system cannot perform its task when one of the following is occurred:

1. If the fingerprint machine has got a problem.

2. If the program is corrupted.

3. If the server cannot work.

4. If the power has gone.

2.5 Assumptions and Dependencies

1. When the main source of power is off, there is alternative any source.

2. If the fingerprint machine is failed, there is reserved fingerprint machine in the store.

3. If the system is corrupted, there is a backup and the proctor can easily restore it.

3. Specific Requirements

3.1 External Interface Requirements

3.1.1 User Interfaces The following screens will be provided:

LOGIN SCREEN: This is the first screen displayed. It will allow users to access different

screens based on their role. Various fields will be: Username, Password, Role (Administrator,

Student Dean, Proctors).

3.1.2 Hardware Interfaces

Screen resolution of at least 800*600 required for proper and complete viewing of screen,

fingerprint machine for taking students fingerprint and support for printer is also required for

printing of reports.

3.1.3 Software Interfaces

Any windows-based Operating system Microsoft SQL Server 2008 as the DBMS-for database.

3.1.4 Communications Interfaces

View of Power and Comm. Port

Electrical outlet using for connecting the power.

Ethernet port: Using for network connection with the computer

through Ethernet

Serial port jack Using for network connection with the computer

through RS232

USB slot: Connect USB peripheral device (for example the U flash disk,

fingerprint sensor and so on)

Audio-jack Connect with extension sound box

According to different the fingerprint machine model.

3.2 Functional Requirements

3.2.1 Taking Attendance

A. Description and Priority This feature is considered as one of the main benefits that Fingerprint attendance system

provides. It is a high priority feature and it is implemented in a way that it can either be

automated or manually taken care of. In the automatic mode the system will take care of

monitoring the attendance process by checking the fingerprint of the student within the

fingerprint device. In the manual mode the student Dean is capable of adding any student

to the attendance list manually and without using any fingerprint devices.

B. Stimulus/Response Sequences

For Automatic mode, the user should press fingerprint sensor in the fingerprint machine.

Then a fingerprint device will take fingerprint of the student and search the matched

fingerprint which already stored in the database and display the corresponding Id number.

For Manual mode, the student Dean should search and choose the student’s name, from

the students list, and his status (absent or present).

C. Functional Requirements

• In order for the automatic mode to work, a compatible Fingerprint device

interface must be installed on desktop computer and install the driver on the

computer.

• Preconditions: All electrical devices must be turned ON.

• Postcondition: The attendance list is updated with the latest student status

whether it is absent or present and saved in the database.

3.2.2 Report Generation

The system will generate based on the format of student status report.

3.3 Performance Requirements

• The software is designed for automating attendance management system using

fingerprint device.

• The software will support simultaneous user access if there are multiple

terminals.

• Fingerprint and textual information will be handled by the software.

• For normal conditions, 95% of the transactions should be processed in less than

5 seconds.

3.4 Design Constraints

This section will indicate the design constraints that apply on the system being developed

and that shall be adhered to during the development phase of the project.

• Programming languages: The server program that resides on the computer shall

be written in Java using the Standard Edition (SE v1.5) development kit.

• Database: Microsoft SQL Server 2008 shall be used as the system’s database

management system. The database shall be stored on the server.

• Development tools: The Eclipse 3.2 IDE and the NetBeans 6.0 IDE shall be used

as the primary development tools to build the server and client programs.

• Operating environment temperature and humidity: The system shall be functional

in both indoor and outdoor environments, even though the system will mostly be

used in interior classrooms under optimum temperatures (20~25°C) and humidity

(30~40%).

9

• Standards: The server program shall be able to work under Windows XP,

Windows Vista, Linux, and the Mac OSX operating systems. The server requires

that the Java 1.5 (or above) Runtime Environment be installed on the computer.

The computer hardware specifications must meet the minimum requirements of

2.3 GHz CPU speed, 2.0GB of RAM, and at least 10 GB of hard disk space for

database storage. The proctor program shall be able to function on all computers

that have the Java Runtime Environment installed.

• Legal Constraints: The only authority that must approve the installation of the

system is the services Student Dean of the educational organization (or any

equivalent division).

• Economic: There is a cost of about $350 per class for the computer, and a cost of

about $100 per Fingerprint machine for each block (terminal). The system will be

released as open source software, therefore there is no profit.

• Sustainability: The system is expected to live for at 10 least years or until a new

version is released to replace it.

3.5 Quality Requirements The product is target towards student attendance management system. The product must load

quickly and work well on a variety of terminals. It must also tolerate wide variety of input

possibilities from a user, such as incorrect responses or unforeseen fingerprints.
