School in Kumbakonam
School administration will usually operate the website, under
Admin Domain. In figure 4 the home page of the website is
displayed. The user with admin credential has to log in first by
a specific username and password. The page offers the option
of adding and editing students’, buses and driver’s
information. Besides, user authentication and authorization
options are also included in this module. Alongside recently
taken actions are shown in the status bar.
The prototype of the system, as designed, is shown in figure
5(a) and 5(b). In this prototype, RFID and fingerprint scanning
and verification mechanism are attached in the door for dual
authentication purpose.
There is a display system in the bus to show the
matching result. GPS is also implemented in the bus for realtime navigation. In windows, there are lasers to protect
students from poking their head or hand outside. If they do so,
an alarm will ring to notify the responsible ones in the bus. All
these devices are connected with a microcontroller which uses
esp8266 WIFI module to send the data in the database. The
overall architecture has been shown in figure 6.
Regarding dealing with underage fingerprints, there are
some issues needing consideration. The distance between
ridges of finger of a child is smaller than adults, this limited
dimension can create resolution problems with the devices,
which may cause problems while used in the algorithms on
ridge distances, thereby decreasing the ability of the
algorithms to deal with the “non-similarities” introduced by
distortion effects and ill positioning of the finger.
Furthermore, there are child behavioural issues that may hinder
in capturing the fingerprint images properly during
authentication [8].
To fix the problem fingerprinting children, images required
to be stored in higher DPI. BIODEV II study shows that a
resolution of 500 DPI can provide good identification using
ridge distances [8]. There is also a 600 DPI Capacitive
Fingerprint Sensor chip which provides a full synthesized
image with no observable error by using a synthesis algorithm.

In the User Domain, guardians need to log in first by a
specific pin number provided by school authority for the
android application.
Figure 7(a) shows the different features of the application.
Where there is Google Map to navigate the bus of their
children, Status to get the real time updates of student’s
entrance and exit in the bus. There are two information options
which provide the detail of bus driver and school authority to
contact in emergency.
Figure 7(b) shows how parents can track the bus in the map to
pinpoint the current location of the bus. All the destinations for
students are also mapped clearly in the android application.
The real-time update of their kids’ status as shown in figure
7(c).This notification will show the entrance and exit with
exact detail containing time and date.
Firstly, this proposed system requires students’ fingerprint
images which is a sensitive issue and should be properly
secured. Thus security is a prime concern. There are number
of encryption techniques available for such purpose [11].
Again there are certain skin diseases that destroy the dermis
and epidermis layer of the skin. As a result, it becomes
difficult to correctly identify different individuals on a regular
basis [8]. Besides, the student have to carry the ID card in
order to scan with the RFID scanner. If somehow the ID card
is lost or forgotten, then there is no way to enter the bus and
follow the system simultaneously. These are some of the
limitations of the proposed system.
In this work, effort has gone into making the system
reliable for the parents. Such reliability issue will be further
intensified in the future. Another plan is to install for IP
cameras which will produce live images from inside the bus, it
will also add speed alert, road change alert, route change
notification, smoke sensor, addition of stoppage ID in the entry
and exit notification etc. An efficient encryption method will
be developed to strengthen security. The main goal is to make
the system more user friendly and helpful.
