This application is a complete package available for Android & Blackberry mobile device, which
helps end-users to take the back-up of their mobile data on a web server. System drives the mobile
data related information (such as SMS, Call log, Contact Info and Latitude / Longitude Info) and
displays on a website. It is a unique backup tool, which internally takes the backup and manages
the data volume.
This application controls a wide range of devices in Android and Blackberry. It maintains the data
backup on time-to-time basis. It can be purchased from client’s web section. Client required a
website that shows the synchronization transaction on both mobile and web server in order to avoid
the complexity in data viewing. We need to design a mobile application, which can smoothly
(silently run within the device) run the application that provides secured data backup for users’
mobile.
Client’s website and the mobile application has been designed and developed to view the entire list
of mobile data information. It can be categorized into different sets such as SMS, Call log, Contacts
Info, Lat Long Infos, etc.
The purpose to design and develop this application is to allow users a comfort and concrete level of
information related to their mobile data. Registration is FREE for all Guest Users (users may have to
pay at a later stage). Mobile no. provided during the registration will be used by the system for
backup. User can add multiple mobile nos. under the same account. Once registration is completed
and a handshake is done on the mobile device through this application, system starts reading the
data from their device and copies it onto its server database.
Users can view the backup data in various filtered ways in order to search the data easily. They can
delete the entry(s) from the web section as and when required.

Project Challenges
Team faced the following challenges:
• Allowing the site to handle millions of users at the same time without slowing down.
• Incorporating web usability principles while developing numerous features designed
for enhancing the users’ Backup Tool experience.
• Harmonizing the simultaneous execution of various device data while maintaining
consistent Load balance.
• Speeding up at all interfaces and instances to fetch as much distinguished data sets
from the server.
• Synchronization with Web Account, Database Servers and Mobile Application.

Manpower
Planning
The following development approach was adopted to equip the site with numerous
features and functionality mentioned before:
• Introduces high level of server and data fetching technology to be implemented.
• Research and analysis has been scheduled in respect to get the actual level of output of data,
which are in a form of different verticals and business logics.
• Development – High Level Coding Standards has been followed for managing backup data
volume, simultaneously synchronization with server for recent updates.
• Precisely need to concentrate in sync with existing and newly available data for backup with
our database for result to get generated.
• The User Interface Layer, which performs the Graphical User Interface of the website.

Architecture
• Mobile Application Flow chart
The application life cycle constitutes the sequence of events that occur between the launch and
termination of application, in the background. With the installation / auto-start of our application, it
starts reading the mobile data such as SMS, Call logs and Contact Info from the device. Once
reading is completed, with the available existing data, it will pass all those data to web server
database through web request. Data is converted into JSON format, before transferring it to web
server. With every successful execution of web request, the next slot of data is packaged for backup
on the web server.
Installation & Auto start of application in the background
CDB, Call Logs, SMS Logs will be backed up by application.
Contact Database (CDB): Phonebook will be logged.
Call logs will be logged. SMS is logged. Inbox, sent items.
Broadcast receiver will provide new entries of (SMS, Call and CDB).

• Web Application Flow chart
The web application life cycle constitutes of managing the web request made by the device and saving
/ fetching data for each mobile data (such as Contact Info/SMS/Call log/Latlong log). Web application
receives the request with all data in JSON format. They parse the data and pass it to the database
CDB, Call Logs, SMS Logs, LatLong Log will be backed up by Remote Server.
Encryption algorithms before storing the data on the server
Parse the data and verify IMEI Number and Phone Number of the user. Based on the verification, enter the data in the particular user database. JSON parsing will be used
User mobile is verified and data is parsed (Contact Info, Call, SMS & Latlong info).
Error MSG will be passed to the client device.
