IoT Integrated Virtual Examination Using Raspberry Pi and Open CV

Abstract:

With the development of modern education, considering the shortcoming of the current online exam system, a new projection of the online exam system based on Raspberry pi IoT is proposed, and the key implementation techniques and methods are also described.

Internet of Things (IoT) has provided a promising opportunity to build powerful Examination systems and applications by leveraging the growing ubiquity of wireless, RFID mobile, and sensor devices. A wide range of IoT applications has been developed in recent years. In an effort to understand the development of IoT in online examination, here we propose the current research of IoT, IoT key enabling technologies, major IoT applications in online examination and identify research trends and challenges

Here initially all the examination details are stored on the server. Then if someone wants to start an online examination, first they should apply the face recognition (in Open CV based) technique. Because sometimes unwanted people also enter to write the exam, this is the best way to identify whether any culprits are found or not. 

Then examine enter to write the exam, here also I apply some security. Nowadays already questions are stored online or on any paper printed copy. But here not like that, if you entered to write the exam at that time only teachers are starting to write questions on the server. This will be printed automatically to the examine browser window. So easy to avoid question paper leakage before the exam.
