This ppt is prepared for zeroth level presentation for the B - TECH project on the topic "Design and Implementation of Improved Authentication System for Android Smartphone Users". we also add the application of the upgraded locking system in lost phone detection procedure
2. Introduction
The devices most often used for IT services
are changing from PCs & laptops to
smartphones and tablets bcoz of portability.
Devices contain increasing amount of personal
info need better security.
If we lost our phone, we want to prevent the
info leakage and can locate easy as possible.
Thus we preset an upgraded Lock Screen
System which encapsulate the lost phone
detection procedure.
3. Overview
In this project we present our upgraded Lock
System, which is able to support
Authentication for the user’s convenience
Provide a good security system
Suggest an upgraded authentication system
Lost phone detection system
If we lost our phone in silent mode,we can send a
present sms to our phone
Phone will send back the exact geo location
Phone will get locked, can erase data
4. Existing System
Pattern Lock
Finger Scan
Keypad Lock
Glass Lock
Slide Lock
if our phone gets stolen, inform the authorities
and hope they get it back by tracking the IMEI
number.
5. Disadvantages of Existing System
It does not serve as a security system and
necessitates extra security applications.
Repetitive input touching is an inconvenience
factor.
security threat of the smartphone by loss or
stolen may cause the users’ private data
disclosure such as contacts, SMS message,
photos, smart car keys, credit cards, login Ids,
and so on.
6. Proposed System
This Lock Screen is shown in figure .
Redundancy input (re – touching the circle) is
allowed and when the circle is touched more
than once , it changes color (maximum of 7
times) so that the user can identify the correct
input.
If we lost our phone in silent mode, we need to
do is send a particular SMS to our phone from
any other phone and your phone will send back
the exact geo location .
7.
The GPS of the phone gets turned on, so it
easy to locate the phone.
if the robber puts a new SIM card the app
detects the change and sends an SMS from the
new SIM to a previously set mobile number.
Also you can erase your phone memory or SD
card with a preformatted SMS so that no one
can access your secure data. During all these
activities your stolen phone will be in lock
mode.
9. Advantages of Proposed System
The Screen receives the “On/Off Broadcast
Receiver” so it is processed with Intent from
Screen-On, activating the Lock Screen Activity.
can erase your phone memory or SD card with
a preformatted SMS so that no one can access
your secured data.
If your phone is stolen the same preset text can
be used to lock the phone,so lost phone
detection process will not be a time consuming
process.
10. Hardware Requirements
CPU type
: Intel Pentium 4
Clock speed
: 3.0 GHz
Ram size
: 512 MB
Hard disk capacity : 40 GB
Monitor type
: color monitor
Keyboard type
: Internet Keyboard
12. Future Enhancement
we can build a web application along with android
application so that when your phone is stolen it can
back up all your contacts and personal data to the
web application before erasing all your secure data
from the memory. Also you can track your mobile
location with the help of a Google map view in the
web.
13. Conclusion
In this thesis, we analyzed the problems in
current HomeLaunchers’ Lock Screens and
suggested improving the authentication systems
for Android smartphones.
The use of our improved authentication system
& the lost phone detection ensures protection of
personal info.
