Task Description
This task involves enhancing the existing LMS module in MEDPlat by implementing a secure QR code–based attendance marking system for learners. Instructors or authorized users should be able to generate a session-specific QR code for a particular course or module session. The QR code must automatically refresh every 2 minutes, generating a new secure, time-bound token to prevent misuse such as screenshot sharing or link forwarding.
When learners scan the QR code, they should be redirected to a unique, short-lived attendance link where they can mark their attendance. Users must be authenticated before submitting attendance. The system should enforce geo-fencing validation and apply IP-based restrictions (one attendance per IP per session) to reduce malpractice. The design must be modular, scalable, and fully integrated with the existing LMS architecture.
Key Outcomes:
- Dynamic QR code generation per session with automatic refresh every 2 minutes.
- Time-bound secure tokens with immediate invalidation of expired QR codes.
- Authenticated attendance submission (only logged-in users).
- Single attendance per user per session enforcement.
- Geo-fencing validation with configurable radius control.
- IP-based restriction allowing only one attendance per IP per session.
- Attendance audit trail capturing timestamp, IP address, geo-coordinates, and device metadata.
- Role-based access control (only instructors/admins can generate QR codes and view reports).
- Session-wise attendance reporting and anomaly detection (duplicate IP, geo mismatch, repeated attempts).
- Scalable and modular architecture aligned with the existing LMS module.
