1. Introduction

1.1 Purpose

This software requirement specification (SRS) document describes the functional and non-

functional description of the Graphical Password Authentication System release version 1.0. The

working and objectives is briefly summarized followed by detailed description of the systems scope,

vision, use case, features and other related requirement issues. In the projects later phases, such as

system design, database design, implementation and testing, this document should be referred as

functional model of the system for release 1.0.

1.2 Document Conventions

All system development activities should follow the final version of this document. Any

discrepancy that found during in later phases should be modified subject to SRS. However, this

document may be subjected to change depending on the decision of the group members.

The typographical conventions used in writing this SRS are:

SRS main headings: Font=Times New Roman, Bold, Size=18.

SRS headings: Font=Times New Roman, Bold, Size=18.

SRS sub headings: Font=Times New Roman, Bold, and Size=14.

SRS Body text: Font=Times New Roman, Size=11.

Header & Footer Font Size: 10, Bold & Italics, Times New Roman. The document contains

header on all pages. The header is the name of the project on top left end and page number on

the top right end of the page.

Bullets are used to denote main points in the section.

1.3 Intended Audience and Reading Suggestions

The document is intended for different types of readers such as developers, administrator and

the authorized users. The rest of this SRS contains an overall description, external interface

requirements, system features and other non-functional requirements.

Developers and testers can go through the details mentioned from topic 2 to 5. Tester can rely

on the document section 4, where each system feature is listed. Database designers will be interested

on sections 2.5 and 3.

1.4 Product Scope

The main aim of this project, Graphical Authentication System is to send an image secretly.

The system focus is to keep the secrecy of the image. The project has immense scope in the fields of

astronomy, industrial implementation, institutional implementation, and scientific fields. In the present

context, the project has wide scope to keep the images privately.
