Inspiration 💡

During the pandemic, we witnessed firsthand the struggles of educational institutions trying to maintain academic integrity in online assessments. Traditional proctoring solutions were either too invasive, requiring extensive software installations, or ineffective at preventing academic dishonesty. We wanted to create a solution that respects student privacy while ensuring test integrity, making online education more trustworthy and accessible for everyone.

What it does 🎯

ProctorAssessment.ai is a browser-based AI proctoring platform that:

Monitors student behavior in real-time using advanced facial recognition
Detects multiple faces, tab switching, and suspicious activities
Provides immediate alerts to instructors about potential violations
Runs entirely in the browser without requiring any software installation
Ensures student privacy by processing all data client-side
Scales seamlessly to support thousands of concurrent test-takers

How we built it 🛠️

We created a full-stack solution using modern web technologies:

Frontend:

- React.js + TypeScript for robust UI
- TensorFlow.js + face-api.js for face detection
- WebRTC for real-time video processing
- Tailwind CSS for responsive design

Backend:

- Node.js + Express for API endpoints
- MongoDB Atlas for secure data storage
- Socket.io for real-time communications
- JWT for authentication

AI/ML Pipeline:

- Custom ML models for behavior analysis
- Real-time face tracking algorithms
- Pattern recognition for suspicious activities
- Audio environment monitoring

Challenges we ran into 🤔
