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 Sole Survivors | Hindusthan College of Engineering and Technology 4
  5. 5. Highly Confidential Security System Software Requirements Specification Sole Survivors Version 1.0 20-12-2012 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.

  12. 12. Highly Confidential Security System Software Requirements Specification Sole Survivors Version 1.0 20-12-2012 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. Sole Survivors | Hindusthan College of Engineering and Technology 12

  15. 15. Highly Confidential Security System Software Requirements Specification Sole Survivors Version 1.0 20-12-2012 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. 2.10 Database Design Sole Survivors | Hindusthan College of Engineering and Technology 15
