IOT Based Question Paper Delivery Box: A Solution towards Preventing Question Paper Leakage in Public Exams of Bangladesh

摘要

A possible low cost solution to prevent the question paper leakage in public exams of Bangladesh has been illustrated in this paper. A GSM based multi-node security system has been designed for delivering the questions to different centers. However, this system can also serve the purpose of delivering other important or confidential deliveries as well. An Arduino Mega micro-controller has been used to control the hardware devices of the system. IR Proximity Sensor, Light Dependent Resistors and Laser Lights have been used to build the prototype sensors for the security system of the devices. GSM Module has been used to send notification of any unusual or suspicious activities during the delivery period via SMS using mobile network to the particular authority. The SMS is then forwarded and illustrated in the admin portal built as a webapp. The architecture of the system has been designed to keep costs low. This system aims to ensure the maximum minimization of question paper leakage during the delivery period to the exam centers.
