Abstract
The smartphone scanner is the best tool to authenticate any
object with embedded Qr codes anytime and anywhere. This
smartphone scanner will make it easier and simpler to encode
the generated code without any difficulty. The need for this
research is to enhance the quality time of authentication which
can now be done anywhere and anytime without the problem
of location and connectivity issue. However, smart card
technology has not been fully embraced, particularly in
developing countries like Nigeria because of our lack of
innovation in information technology. As a solution, this work
presents a real time student identity card authentication
system with the aid of android phone camera scanner in built
function. The developed system accepts as input, a
matriculation number which is unique for every student and
encrypts it into a two-dimensional bar code using a QR
generator. The generated QR code is then embedded in the
identity card alongside other details of the cardholder which
produce a dynamic authentication output. A software
application that functions as a QR scanner is pre-installed on
the smartphone. This makes it possible to reverse this process
during authentication for a reconciliation of the decrypted
code with the student matriculation number. The result of the
experiment reveals that the smartphone scanner is effective
and faster to authenticate the embedded qr code trademark
than any other means of authentication.

INTRODUCTION
Authentication of any object with trademark is indispensable
in this era of Information Technology as production of fake
items has become rampant. The use of smartphone scanner to
verify the originality an item is necessary as it is fast and easy
to implement and use (Bajpai and Agrawal, 2013).
Authentication of a student identity card with the aid of a
smartphone scanner is a method of identifying the quick
response code trademark embedded in each student identity
card. To automatically identify a student is a token of an eye,
smartphone are increasingly being used. Authentication is the
process of confirming the real identity of an attribute of a
piece of data claimed true by an entity. A student Identity card
is said to be the summary of a student's information and with
the speedy increase of students in our institutions, it is now a
must for every institution to have a means of automatic
authentication of each student. It is highly essential for an
educational institution to provide Identity card dynamically
with quick response code embedded and that can easily be
authenticated using a smartphone for every student.
Automatic Authentication of Student Identity card with Quick
response code and smartphone system is actually means of
maximize the usage of student ID card and also by doing that,
it will upgrade the system that been used in the Identification
of student card nowadays. With the successful implementation
of dynamic Qr code in student identity cards, it can also help
in other students activities within the campus, for example,
student lecture attendance, library usage, hostel insurance and
while taking the final examination. Other than that much
higher institution still uses their own in a house security guard
to check student in and out during peak hour. Rather than use
a person, why not all higher institutions have their own
automatic barrier that needs the student to swipe their own
identity card before entering campus areas. This will totally
increase the safety of their learning places.
The rapid development of various aspects of computer
technology gives rise to the usage of various information
technology gadgets in our day to day activities (Richard,
2102). In this research work, a quick response code is
embedded to student identity card and smartphone is used to
authenticate the encrypted embedded quick response code
automatically which will redirect to a site to authenticate the
encrypted code. This proposed work uses a web application to
generate an embedded student identity card locally on the
computer system and whenever the need arises for
authentication of the card, the identity card is placed under
smartphone camera, the smartphone scan the embedded quick
response code and decrypt the encrypted details for
verification. This process is purely automatic authentication
process. It does not require manual entry on matriculation
before performing the authentication process.

RELATED WORK
There are many proposals for a student identity card with
quick response code and smartphone. Most of them to focus
on the application of static nature of qrcode verification which
does not redirect to the webpage where the code is being
generated and also internet connectivity of either the
smartphone or the software application, while the closely
related make use of manual input of matriculation number
before authentication. In this section, we will mention briefly
a few of these proposals.
Bajpai and Agrawal (2013) presented a paper on personalized
data, signature and picture of cardholders were captured, their
systems generated barcode in 2-dimensional formats which
represents the captured data and embedded this barcode image
on the identity card. The validation and authentication of this
card they produced were done on an online centralized
database. The intention of their authentication was to match
the encrypted unique identity of the person in the barcode's
image with the one in the online central database. The major
shortcoming of their work was that solely depends on internet
connectivity for its operation.
Singhal and pavithr (2015) use quick response code and
smartphone for verification and authentication of an
educational certificate. In their work, the QR code was
embedded on the student certificate that decrypts the signature
from the university's public key in order to generate the hash
value for verification. For the certificate to pass the
authentication process, the hashed value generated from the
certificate must match that of the university's public key
otherwise, the certificate will not pass the authentication
process. This work was a purely online system which will
render the authentication process unless whenever there is no
internet connectivity.
Cho and Bae (2014); Masalha and Hirzallah (2014); Kumar
and Kareemulla (2017) these researchers proposed an online
attendance system for both the staff and student using QR
code and Smartphone. In this work, the Staff is required to
generate a QR code that would be scanned by the students and
sent through the wireless network for necessary automatic
attendance checking. In other to avoid proxy of attendance,
Kumar and Kareemulla introduced fingerprint and voice
verification to authenticate the attendance system.
Ayeleso, et al. (2017) proposed an embedded QR code on
identity card to be given to students and introducing
Smartphone App to authenticate the embedded QR code.
Their proposed system is an offline system which does not
require a network connection for authentication. The major
shortcoming of their work is that student matriculation
number has to be manually inputted before authentication.
The first three work reviewed earlier shows that their
proposed systems work with the internet connection. That is
their operation is solely dependent on the availability of
internet access and the cost implication can be a barrier of
adopting the system. The fourth reviewed work is closely
related to this work since is offline but the issue of manually
inputting student matriculation number before authentication
gives rise to this offline and automatic QR code
authentication.
MATERIAL AND METHOD
The proposed system was modeled using a Quick Response
code and smartphone for dynamic authentication of embedded
code. The quick response code is read by an imaging device,
such as camera and authenticate by smartphone until the
image can be appropriately interpreted. Data is then extracted
from patterns present in both horizontal and vertical
components of the image. The Figure below shows a sample
of an unencrypted QR code that will be needed by the
proposed system.

Performance Goal
Different scanners were used to carry out the experiment and
it was discovered that there were no significant differences in
the authentication processing using the different scanner but
the time taken by each scanner makes the smartphone looks
preferable than other since it take little time to verify the
embedded code. That is, the type of tool used for
authentication will determine how fast the process will take
and it was discovered that subsequent scanning of this code of
all devices takes little time compare to first scanning process.

CONCLUSION
From the output of the discussion of result and experiment
performed, it can be concluded that any smartphone with
quick response code reader embedded will be able to capture
the exact encrypted data faster during the authentication
process. This aim of this research work was achieved. As the
embedded code on the student identity card was able to be
decrypted automatically with the aid of the smartphone quick
response reader without the need for any manual input of
previous data during the verification stage. In the future, this
application can be applied to various activities that require
verification and authentication. It can also be used in a
supermarket for stock price list instead of the barcode.
