✅ Completed Features

Authentication

• Google OAuth 2.0 only — No email/password login exists
• Role-based access control — Student, Teacher, Admin roles strictly enforced
• Pre-registration required — System never auto-creates users
• Unauthorized email rejection — Clear denial message with email shown
• JWT session management — 8-hour session timeout
• Audit logging — Every login attempt logged with timestamp

Student Portal

• Mobile-first, minimal dashboard
• QR code scanner (camera-based + manual code entry)
• 4-step attendance flow: QR → Roll Number → Face + GPS → Confirmation
• Roll number cross-validation against database profile
• Live selfie capture for face verification
• Real-time GPS location capture
• Geofence validation (configurable radius, default 100m)
• Duplicate attendance prevention
• Attendance history with filter (all/month/week)
• Attendance trend chart (Chart.js)
• Below-75% attendance warning
• Fraud alert notifications

Teacher Dashboard

• Sidebar navigation with all sections
• QR Session Management — Create, rotate (60s), end sessions
• Auto-rotating QR codes every 60 seconds
• Geofence configuration with GPS capture
• Live Overview — Real-time stats: Present, Absent, Total, %
• Roll-wise attendance grid (color-coded: green/red/yellow)
• Live activity feed (updates every 15s)
• Present/Absent split view
• Full attendance table with GPS, face score, fraud flags
• Fraud alerts with resolve functionality
• Student roster view
• Analytics: session charts, status distribution, at-risk students
• Report generation (preview + CSV export + print)
• Session history table

Admin / Developer Panel

• Secure admin-only auth wall (Google OAuth)
• User Management — Add, enable/disable, delete users
• Role assignment (student/teacher/admin)
• User search and filter by role
• CSV user export
• Session monitoring with force-end capability
• Full attendance records with multi-filter
• Bulk CSV attendance export
• Fraud Detection Center with resolve
• Audit Logs — Every action logged with user, action, status
• System Configuration (QR interval, geofence, thresholds, OAuth)
• Global Analytics (daily trend, user distribution, fraud summary)
• Live session monitor

AI Fraud Detection

• Device fingerprinting (detects same-device multi-submission)
• GPS validation (geofence breach = fraud flag)
• QR token expiry enforcement (60-second rotation)
• Duplicate attendance blocking
• Fraud alert creation and teacher notification
• Roll number vs. login email cross-validation
• Behavioral pattern logging
• At-risk student prediction (below 75% threshold)

Security

• No passwords in the system (Google OAuth only)
• Backend token verification flow
• Session expiry (8 hours)
• Role isolation (student can't access teacher routes)
• All sensitive actions logged
• CORS-safe client-side architecture
• Zero demo/mock data policy enforced

🚀 Setup Instructions

1. Configure Google OAuth

1. Go to Google Cloud Console
2. Create a project → Enable "Google Identity Services"
3. Create OAuth 2.0 Client ID (Web Application)
4. Add your domain to authorized origins
5. Copy the Client ID and paste in js/config.js:

const APP_CONFIG = {
  googleClientId: 'YOUR_REAL_CLIENT_ID.apps.googleusercontent.com',
  // ...
};

2. Add First Admin User

Use the Table API or Admin Panel to insert the first admin:

{
  "id": "admin-001",
  "email": "admin@yourinstitution.com",
  "name": "System Administrator",
  "role": "admin",
  "is_active": true
}

3. Add Teachers & Students

Through the Admin Panel → User Management → Add User

Students must have:

• Valid institutional email matching their Google account
• Unique roll number
• Active status

4. Deploy

Use the Publish tab to deploy your project publicly with one click.

🔒 Security Notes

• Never share admin credentials — all logins are via Google OAuth
• QR codes expire in 60 seconds — screenshot sharing is impossible
• GPS geofencing prevents remote attendance marking
• All actions are audit-logged — full accountability
• Device fingerprinting prevents multi-device fraud
• No demo data — system only shows real entries from real users

---

📋 Next Steps / Recommended Enhancements

• Integrate real face-api.js facial recognition with stored face descriptors
• Add Firebase/WebSocket for true real-time push updates
• Email notifications for fraud alerts and low attendance
• Mobile app (React Native) for native QR scanning
• Batch student import via CSV upload
• Multi-institution / multi-tenant support
• Advanced ML model for behavioral fraud detection
• Push notifications via Web Push API
• Automated attendance reports via email schedule
• Integration with LMS systems (Moodle, Canvas)
