Abstract
Every year during time of examination we will come across some news in the newspaper and television about question paper leakages and hence the exam is being postponed / cancelled. Sometimes the information related to question papers leakage will not be known to the universities itself. Hence some students get good ranks by these papers and those students who had really worked hard have to compromise with less rank and this factor will have negative effect on the growth of the society. Thus by considering the problems faced by the students and society a plan has been made to implement a system which will help to stop this malpractice of leaking the question paper.
we overcome such problems by SLP(Secured and Leakage Proof system) in our project. In SLP System,
GSM modem is connected to the box containing question papers along with the microcontroller. Mobile of Authorized person in University board acts as the Base station. To open the question paper box, RFID is needed to be swiped with a valid RFID tag and then RFID will compare with data such as RFID address. If the comparison is failure , then controller sends ”WRONG ACCESS” message to the Base station through GSM modem along with the buzzer alarming . If anybody tries to open the box before the pre-defined time with a valid RFID tag also, then controller sends ”RULES VIOLATED” message to the Base station through GSM modem. If controller finds the valid card swiped on pre-defined time, then it sends a confirmation message to base station and sends a signal to unlock the magnetic lock.GPS Module keeps track of the box containing question papers, which will be carried from the university to various colleges. If box carrier deviates from the pre-defined path, GPS module alerts the controller and hence in turn sends a signal to GSM Module to send message to inform the base station.
