StackNoble Secure Exam,
locked down at the OS level.
A desktop kiosk app that wraps the Stacknoble exam experience in a full lockdown — fullscreen enforced, shortcuts blocked, tampering prevented, before a single question loads.
Every angle of exam-day tampering, covered.
Fullscreen Kiosk Mode
Cannot exit without ending the session first — no minimize, no resize.
Keyboard Lockdown
22 shortcuts blocked during the exam, including Alt+Tab, the Windows key, and Task Manager.
Copy/Paste Protection
Disabled everywhere except the answer input fields.
Auto Exam Detection
Kiosk mode activates automatically on exam URLs — no manual setup required.
Crash Recovery
Automatically reloads and resumes the session if the app crashes mid-exam.
Memory Management
Cache is cleared automatically once usage passes 500 MB, keeping the app stable on long sessions.
DevTools Disabled
Browser developer tools are fully disabled in the production build.
Screenshot Detection (Partial)
A PrintScreen key press is logged as a violation. This is detection-only — it doesn't block OS tools that skip the clipboard, like Snip & Sketch.
Blocked in four layers, not one.
Windows Game Bar allows screen recording, overlays, and chat — a real security hole during an exam. Instead of relying on a single safeguard, it's blocked at every stage.
Registry (Install Time)
The installer disables AppCaptureEnabled, GameDVR_Enabled, and UseNexusForGameBarEnabled via a PowerShell script.
Runtime Detection (Every 2s)
The app polls for GameBar.exe throughout the exam and kills it immediately if found.
Warning Overlay
A red, shake-animated warning is shown on screen to the student for 10 seconds.
Violation Log
Logged as a critical-severity violation, visible to staff in the review panel.
Registry keys are restored automatically on uninstall.
Layer one: locked down before it starts
This desktop app enforces OS-level lockdown — fullscreen, blocked shortcuts, no copy/paste, no Game Bar — the moment an exam URL loads.
Layer two: monitored once inside
Real-time, in-browser AI face and object detection runs during the exam itself — evidence captured, reviewed by a human, never stored as video.
