CUSTECH Osara — Enterprise Online Examination System
"A production-grade exam platform with Electron lockdown and advanced AI proctoring."

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.
