Remote Proctoring
Remote proctoring is the process to authenticate, authorize and control online examination process in scalable manner.
In traditional exam process an invigilator need to be present at the exam center to validate candidates appearing for the exam. For each exam center of around 30-50 candidate you need one invigilator.
So for conducting exam of 1000+ candidates you would need more than 25 invigilators controlling the exam process.
