Smartphone Security and Contact Synchronization(SSCS) is an android application that solves the problem of losing your mobile contacts when you lose your smart phone, informs to your friends about your new number when you change your SIM card and helps you track your lost android mobile handset. This reseach work has been practically implemented and published in International IEEE Conference - CSNT 2014.

2. Current Scenario – About Smartphone Theft
• Every year, smartphones costing $30 billion are
lost/stolen.
• Worst part – most of these smartphone theft cases
remain unsolved, and yet no interest in solving this
problem from manufacturers of these smart gadgets.
• Smartphone Theft – fastest growing undetectable
crime.

3. Have you ever wondered ?
What would happen if you lost/changed your
smartphone?
• Contacts Lost
• Transferring Contacts.

4. SSCS : A complete solution to above problems
The “Smartphone Security & Contact Synchronization (SSCS)” is an
innovative idea that will serve to solve the following challenging
problems regarding smartphones:-
Help the smartphone owner to track his/her lost android
smart phone.
Solve the problem of smartphone owner’s credentials being
exposed/ leaked.
Solve the problem of losing/transferring contacts when you
lose/change your smart phones.
Informing your friends about your new contact after you change
your SIM Card.
Remotely control your device.
Find phone by making it ring/vibrate even in silent mode.

5. Proposed System
The idea is to develop an online service and an android
smartphone application that works together. The application
aims to solve the problem of losing mobile contacts by
maintaining its contact details automatically in an online contact
base ie Google Spreadsheet. Google Docs API will be used for
this.
With this application, each contact on a user’s smartphone is
synchronized with it, and each time the user changes his/her
mobile number, every synchronized contact will receive a
message or an e-mail about user’s updated contact
information.

6. Proposed System
From a security point of view, the main motive of the
application is to keep a track of our mobile handset and catch
the thief. With this application, the original mobile user can
track his/her lost mobile phone. And if a malicious user
changes the SIM Card, his mobile number will be sent to the
alternate numbers entered by the original user at the time of
application installation. A special code messaged from any
mobile number will initiate the GPS tracking.
The Siren Feature will help to trace the smartphone despite it
being in the silent mode.

8. FLOW CHARTS – Mobile Safety/Security
1) SIM Change Detection

9. 2) GPS Tracking Activation/Deactivation

10. 3) Siren Functionality

11. 3) Inform to Friends

12. Uniqueness About Our Application
The situation right now is that most smartphone developers are working on
better hardware of devices. Due to this, a few basic facilities that every
smartphone should have, i.e. anti theft security, contracts synching problem
etc., is being overlooked.
Even though, there are many 3rd party applications on the play store which
try to provide facilities for contact synchronization, smartphone security.
However, they have their limitations too:-
• Not a complete package.
• Lack multi-purpose capability.
• Storage Issues.
A complete solution all packed in a single application with no hassles is still
not available on the Google PlayStore.

15. Future Scope
Great present & marvelous future ahead :
• We can have a complete backup of messages, call
history etc. into the Google spreadsheet.
• The feature to automatically capture thief’s photo
when he/she logins to the smartphone for the first
time.
• The ADB Lock feature.
• Wipe Data/Factory Reset Protection can be added
to enhance application’s capability.
