Secure Examination Paper Distribution System

Creating a secure examination paper distribution system is essential to maintain the integrity and confidentiality of exams.

Core Features

1. User Authentication and Authorization

  • Secure login system for different user roles: administrators, examiners, and invigilators.
  • Role-based access control to ensure data privacy and security.

2. Secure Paper Upload and Management

  • Paper upload by administrators and examiners.
  • Encryption of papers upon upload to ensure confidentiality.
  • Version control to manage updates and revisions to papers.

3. Access Control and Distribution

  • Granular access control to ensure only authorized personnel can access specific papers.
  • Scheduled distribution of papers to ensure they are available only at the specified times.
  • Logging of all access attempts for audit purposes.

4. Exam Paper Viewing and Download

  • Secure interface for authorized users to view and download examination papers.
  • Watermarking and tracking to prevent unauthorized sharing.
  • Time-limited access to downloaded papers to ensure they are only accessible during the examination period.

Tech Stack

  • Backend: Node.js, MongoDB
  • Frontend: React
  • Cloud Services: Amazon AWS (for storage, hosting, and other services)
