Electronic Protection for Exam Paper Leakage
[attachment=68440]
Abstract
Education is simply the soul of a society and
examination is the heart of education system. Today, when we
come across the news of malpractice in exams, we realize that,
knowingly or unknowingly this soul has got irrecoverably
corrupted. The main reason for this is exam paper leakage. The
serious actions must be taken to prevent this. So we propose an
electronic system here to detect and prevent examination paper
leakages.
In this proposed system the question papers will be sent to the
examination centers in the electronically locked box, which
cannot be opened before the predefined date and time. The box
can be opened by authentic user only. The question papers
are actually present in sub boxes. These are password protected.
The exam controller will send a message containing password to
open individual sub box. When the Password, date and timing
matches, the box will open through a motorized mechanism.
This will help the papers to remain locked and sealed till the
time of examination. The light sensors are used to detect any
sort of unauthorized tampering
INTRODUCTION
N examination is an assessment intended to measure the
knowledge, skills, aptitude, physical fitness or
classification in many other topics. A test may be
administered orally, on paper, on a computer or in a
confined area that requires an examinee to physically perform
a set of skills. [1]
The history of examination is very wide. The first a
nationwide standardized test was implemented in China,
which was called the imperial examination. The main purpose
of this examination was to select able candidates for different
governmental positions.
The imperial examination was established in 605 AD. And
thenafter different countries adopted the examination systems.
England had adopted this examination system in 1806 to
select the applicants for positions in Civil Services. This
examination system was later applied to education and
became a worldwide standard. [1]
Every year news flashes in newspaper and television during
the time of examination that the exam is being
postponed/cancelled due to the leakage of question papers
LITERATURE REVIEW
The question papers are distributed in sealed boxes. This
system is being followed since many years. The
disadvantages of this system are it may lead to leakage of
question papers at various instances in the journey of box
from printing location to examination centers. This
happens due to easy tampering of sealed boxes and more
human interference.
Other method involves the e-copy of the question
papers mailed from the university to the colleges prior to
examination. The colleges take the printouts of the question
paper and then are distributed to the examinees.
This method also has many disadvantages. The website
may be hacked, server may also breakdown and number of
colleges had to take printouts which involves the threats like
power failure, system failure and may lead to leakage or
problems in conduction of examination.
The idea for the proposed system which involves the
electronic protection is derived from modern day applications
like Electronic lockers in bank, Home security systems,
office security systems and other security enhanced
electronic systems.
PROPOSED SYSTEM
A Main box contains the sub boxes in which question
papers are proposed to be kept. The RFID tag and GSM
modem are connected to the box along with the ARM
processor.
GSM modem interfaced to ARM processor always sends
the report of activities to university via text messages. The
overview of proposed system is shown in figure
WORKING OF PROPOSED SYSTEM
To open the box, RFID is needed to be swiped with a valid
RFID tag at predefined date and time only. The RFID module
will compare with EEPROM data such as RFID address, RTC
date and time.
If the RFID address is wrong, then processor sends
“ANAUTHENTIC USER” message to the university through
a GSM modem and if anybody tries to open the box before
the pre-defined date and time with a valid RFID tag also, then
processor sends “OVERRULED” message to the university
through GSM modem.
The box will be open only when swiped with a valid RFID
tag at predefined date and time and processor sends “MAIN
BOX OPENED” message to the university.
Then a password is sent from the university to the college
to open the particular sub box which contains the question
papers. If the person enters the wrong password, then
processor sends “WRONG PASSWORD ENTERED”
message to the university through GSM modem. If the person
enters the correct password, then sub box is opened with the
help of the motorized mechanism
CONCLUSION
A cost effective system is proposed here which uses RFID,
GSM and Real Time Synchronized clock. Examination
section of university can deliver the question papers to the
examination centers by password protected electronic security
system. All these question papers will have next level security
using RFID. Using GSM each activity involving opening and
closing the box can be monitored in real time by university
examination centre.
