🔒 Screenshot Blur Detector

A small experimental React app that blurs content when a screenshot attempt is likely — based on user keypress behavior.

🛡️ System-level screenshot events are intentionally blocked by browsers to protect user privacy and security.
This project explores a creative heuristic-based workaround using a custom React hook.

🧪 Workaround Experimented

• Predicts screenshot intent based on key combinations like Cmd+Shift (Mac) or PrintScreen (Windows)
• Applies a blur effect on sensitive content when such actions are inferred
• Uses keydown, keyup, and contextmenu events to monitor common triggers
• Built using a custom React hook for easy integration into any component

ℹ️ Note

This is an experimental workaround — browsers do not support direct screenshot detection, as system-level events are intentionally restricted to uphold user privacy and security.
The approach here explores how far we can go using available browser events.
