1. Introduction
In day-to-day life it is quite hard to remember all confidential data like Mail Id, Password, bank
account number, Insurance policy number, PAN number, Driving License number, education certificate
Numbers, Some highly value scan copy, some confidential photo, music and videos. Crypto Locker is a
highly secure web application to store all confidential data in single credential.

1.1 Methodology
The Rational Unified Process brings together elements from all of the generic process models,
supports iteration and illustrates good practice in specification and design. The RUP is normally described
from three perspectives:


A dynamic perspective that shows the phases of the model over time



A static perspective that shows the process activities that are enacted



A practice perspective that suggests good practices to be used during the process

Inception
The goal of the inception phase is to establish a business case for the system. Identifying all
external entities that will interact with the system and defining these interactions. This information is used
to assess the contribution of system to business.

Elaboration
The goals of the elaboration phase are to develop an understanding of the problem domain,
establish an architectural framework, develop project plan and identify key project risks.

Construction
This phase is concerned with system design, programming and testing. Parts of the system are
developed in parallel and integrated during this phase.

Transition
This is the final phase of RUP and is concerned with moving the system from the development
community to the user community and making it work in real environment.

1.2 Purpose
Crypto Locker is a web application developed for secure and easy access of data. Crypto Locker
is a useful and convenient application that spares you the trouble of remembering the passwords and
securing the files. This application helps people to store their passwords and various types of files like
photos, music and videos in a secure and efficient manner. The application which we develop here uses
state of the art encryption technology to secure files and access over anywhere in the world using the
internet.

1.3 Scope


There are two basic users – Administrator, User.



All users have their own profile in Crypto Locker.



Administrator has an ability to manage the registered user profiles and organize the files stored in
the server.



Administrator has the ability to provide the notification message to the logged users via webpage.



Public peoples are the users used this web application to protect their important details in single
credentials.



Citizens (users) can access their files through internet from anywhere in the world.

1.8 Overview
The SRS will include two sections, namely:
Overall Description
This section will describe major components of the system, interconnections, and external
interfaces.
Specific Requirements

faced by the system.

2. Overall Descriptions
2.1 Product Perspective
The Crypto Locker is available for use by the administrator and the user. The administrator and
users will use the webpage as a front end. The browser goes through an http server. Application server
manages the connection between the front end and backend, all types of information and data, that are
necessary for the users are stored in DB2.

2.5 User Characteristics


Both users and administrator on internet will be using HTTP protocol.



Users use the FTP protocol for uploading and downloading the files from or to the server.



Administrator configures the SMTP Server for sending the mail to the user.

2.6 Constraints


GUI is only in English.



Login and password is used for the identification of the user (public people) and administrator.



Limited to HTTP, SMTP and FTP protocol.



Centralized server is used.

2.7 Assumptions and Dependencies
Crypto Locker is a platform independent web application. It is assumed that the client or user
computer has latest browser with JavaScript enabled. In addition, Firefox and Internet Explorer need the
flash plug-ins to play the media files. For configuring the SMTP Server it needs the Linux operating
system with at least kernel version 2.6.30, if server is in windows then it may need Windows Server.
Sending the message (SMS) to the users mainly depends on the network operator.

2.9 Use Case Model Survey

Users can upload their files in their own personal locker. The locker includes various subsets like
Music locker, Image locker, Video locker, Password locker and Bank Account Information locker. Users
can access their personal (uploaded) files through internet. Users can participate in forum discussions to
clarify their doubts and also able to view the notifications sent from the administrator.

Administrator
Administrator has the ability to manage the registered user’s profile. Administrator can send the
notification to the logged user about any changes in the service and also clarify the user’s doubts and
questions about the service.

System
While users are trying to create their account, Crypto System validates the user’s details and post
the message (success or failure) to them. Server has the ability to send the “Password reset link” to the
user’s mail, if the user forgets the password to access their account. It automatically blocks the abuse
users. When users are uploading the file, the system encrypts it by using the algorithm, when the users are
downloading their file, the system decrypts it.

The user is made to fill all the mandatory fields, each user must choose a unique user name. If the
user has filled a name that is already present in the database, then the user will be prompted to fill in a
different username. After this the user must enter the new password twice. When the user clicks the
submit button the database verifies all the mandatory fields are filled or not. When all the fields are filled
the verification mail is automatically send to user’s mail, after click the verification link the user is
registered, otherwise the user is made to fill the fields again.
