Client

Requirement

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.

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.

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.

Broadcast receiver will provide new entries of (SMS, Call and CDB).

Contact Database (CDB): Phonebook will be logged.

SMS is logged. Inbox, sent items.

Call logs will be logged.

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

Error MSG will be passed to the client device.

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).
