Currently, the online examination system has gained a lot of momentum, and that is because of its fast speed and accuracy. Additionally, it requires minimum human resources to execute the examination when you create online tests.

What is the Online Examination System?

Under a secure online examination system, students can get their user id, and password along with their admission card. In the examination server, the id gets saved automatically. The student receives a message at a particular time to start the examination. The server keeps all the answers given by the test maker, along with his or her information.

Furthermore, online examination technology doesn’t allow the student to change the answers after the exam is over. It also made the process of answer checking hassle-free and comfortable as computers tend to be more accurate than humans and provide faster results.

Importance of Security During the Online Examination

There are many benefits of an online examination system, but besides benefits, the app’s security cannot be neglected. The online examination system offers flexibility and scalability to manage the process in a smooth manner. By exam security, the ed-tech app developers mean taking measures to examine fairly.

Some of the techniques to make online exam secure are:

The remote proctoring system allows students to access the examination window only. Additionally, features like copy, paste, and add to shortcut are prevented entirely. The system also has a feature that notifies the examiner if the user tries to navigate away from the screen.

Above all, the entire communication between the server and the examination client is encrypted. High-level encryptions are also used under an online test app to encode data that can’t be decoded easily. It ensures the confidentiality of the question banks which get exchanged between the client and the server.
