Rectify - Automated Exam Proctoring tool for Online Exams using Face Recognition | MesoHacks Submission | Education Track

🚩 Overview

During COVID 19 pandemic, online education has become a common norm in schools and colleges, and students themselves are adapted to this online environment of education, as classes are being held in online mode, exams are also conducted online and students tend to cheat in those exams due to lack of security and no physical guarding by professors/teachers which is monitored live, so here is my solution to the problem! Now teachers can monitor students' live even in online mode!

Disabled Tab Change Tab changing is strictly monitored during the live examination, if any student tries to open any other tab, the model detects and reports it immediately to the professor that student is changing the tab as well as the number of times he changed
Prohibited Object Detection! Some prohibited objects such as books,any other laptop is also detected if any student tries to choose this way of malpractice

Other Features :

1. Dynamic Teacher's Dashboard
2. Sorting and searching functionalites in Professor's Dashboard
3. Return Back to exam within set time (done because if any student losses connection during the exam) he can return back to it.
4. Exam creation dialog box which automatically copies generated exam code to clipboard

Note: - Since in the current iteration of the project I am using google form link from professor instead of making questions in the application itself, it is impossible to put key listeners and right click prevention in it since its a third party app and React prevents it due to security reasons. To test these features, please do ctrl press, alt press and right click on left side of screen only.

🚩 Future Scopes:-

Feature	Explanation
Creating Exam Feature in the application itself	Instead of using a external link(google/microsoft forms),exam creation in the web-application itself would provide more security and better user experience to the product.
Class Management	All class management activities (branch/section wise) separately for every year students, creating assignment in the application itself assigning tasks and keep a record of every student activites individually in different sections.
Video Calling support	Video calling support between students and teacher for quick doubt resolve and better teacher to student interaction
