CUSTECH Osara - Online Examination System
"A CBT exam platform with an Electron lockdown client and AI proctoring, built as a project."
The Challenge
Online exams are vulnerable to various forms of cheating, from simple screen switching and unauthorized shortcuts to sophisticated photo/video spoofing and secondary device usage. Universities need a way to lock down the testing environment while monitoring student behavior without constant human supervision.
The Solution & Architecture
I built a multi-layered security system. The Electron kiosk client provides a complete lockdown, blocking system-level shortcuts (like Alt+Tab or Win+L) and unauthorized background processes. Simultaneously, the AI proctoring engine uses 68 facial landmarks to track head pose, eye gaze, and mouth movement. It also includes an active "anti-spoofing" challenge system that requires students to perform specific actions (like blinking or smiling) to verify their identity.
Impact & Results
The system provides a robust, NDPR-compliant framework for large-scale examinations. It automates the detection of violations like speech, secondary displays, or head-turning, allowing faculty to review flagged incidents through a dedicated dashboard with forensic exports.
