Session Creation → Generate QR + network capture
Live Monitoring → Real-time attendance updates
Analytics Dashboard → Student insights and reports

🛡️ Admin Journey:

User Management → Approve students/teachers
Security Monitoring → Audit logs and validation reports
Predictive Analytics → At-risk student identification
Export Reports → CSV/JSON data export

🔥 KEY FEATURES FOR SIH PRESENTATION

🎯 Anti-Proxy Mechanisms (UNIQUE SELLING POINT)

// Multi-layer validation example
const validationResult = {
  proximity: {
    ip: ✅ "Same network",
    wifi: ✅ "College-WiFi-Main", 
    bluetooth: ✅ "Teacher device detected",
    geolocation: ✅ "Within 50m radius"
  },
  biometric: ✅ "Face match: 94.2%",
  security: ✅ "Session token valid",
  spoofing: ❌ "No suspicious activity"
}

🛠️ TECHNICAL IMPLEMENTATION DETAILS

Core Technologies

Frontend: Next.js 15, React 19, TailwindCSS
Backend: Node.js, Next.js API Routes
Database: CouchDB (Production), IndexedDB (Offline)
Authentication: NextAuth.js with admin approval system
Face Recognition: face-api.js with TensorFlow.js models
PWA: Service Workers, Web App Manifest

Security Implementation

// Proximity validation pipeline
export function validateProximityFactors(sessionNetwork, studentNetwork) {
  return {
    ip: validateIPProximity(sessionNetwork.ip, studentNetwork.ip),
    wifi: validateWiFiSSID(sessionNetwork.ssid, studentNetwork.ssid),
    bluetooth: validateBluetooth(sessionNetwork.ble, studentNetwork.ble),
    geolocation: validateGeolocation(sessionNetwork.geo, studentNetwork.geo),
    overall: primaryFactorsPassed >= 2 // At least 2/3 must pass
  };
}

Predictive Analytics

// At-risk student prediction
const riskScore = calculateRiskScore({
  attendanceRate: 65.2,
  trendDirection: -12.5,
  consistencyScore: 0.3,
  engagementLevel: 'low',
  lastActivity: '7 days ago'
});
// Result: 78% risk (HIGH) - Intervention needed
