Abstract
Present android-based location and message
sharing system asks to input the personal information which
fails to protect the privacy of information, has no centralized
database which is causing the problem of data management
and portability, and one main drawback is unable to have a
secured two way communication between webserver and
android based application. And this Android-based Location
and Message Sharing System (ALMSS) is proposed for solving
above mention problem. The proposed system uses Java
programming language for android mobile user application,
PHP programming language as webserver, MySQL as external
database to store the data, JSON as intermediary between
android platform and webserver and uses symmetric
cryptography while communicating between android device
and webserver which finally assures the protection of
information.
INTRODUCTION
Today’s age is the world of technologies, where lots of
inventions and discoveries have made everyone to rely on
the use of latest technology. Knowingly or unknowingly we
are taking the benefit of the technology. Today one can share
information with others using the communication
technology. One can know what is happening in different
parts of the world within a click. It is possible due to the
development in the internet services through which one can
share the information with the rest of the world.
Internet has brought revolution in the field of
communication. One can use internet for various purposes
depending upon the nature of work. But the main uses of the
internet in these days are sharing of information. The main
application of internet is web services where internet plays
an important role
BACKGROUND
This section presents the background environment for
location and message sharing system.
GPS Technolog
The Global Positioning System (GPS) [2] is a global
navigation satellite system deployed by the US Department
of Defense and maintained by the US Air Force. GPS is a
space based radio navigation system that provides accurate
location and timing services to anyone with a GPS receiver
RELATED WORKS
The various researches have been done and are going on
location based project and in the same ratio various
applications have been developed on location-based and
message sharing system.
The various locating technology as described in [10] are
summarized as follows:
1) GPS: It locates a user through a device that is in
communication with a constellation of satellites.
2) Wireless Position: It locates a user using both
private and public wifi access point, users can be
mapped according to the location of these access
point.
3) Cellular Identification: It locates using cellular data
of mobile phones.
4) IP Location: It locates users using the IP address of
the Internet network.
Among the various location technologies, GPS is the
most and accurate way to locate user. It locates a user
through a device that has GPS functionality such as mobile
phone. Various location sharing applications is gaining
popularity due to the growth of the GPS equipped
smartphones. With the emergence of the GPS capable
mobile, users started to write a small application passing
location data to a central server to make their location
available to other users
