Development of a Secure Online Examination Platform with Browser Lockdown Capabilities

The client faces challenges in ensuring exam integrity during online assessments due to potential cheating, privacy breaches, malware threats, and security incidents. Existing online exam systems require enhanced security mechanisms to enforce strict test environment controls and prevent unauthorized actions such as copying, window opening, or application switching, especially across multiple web pages.

A mid to large-sized online education provider delivering examination services across various medical disciplines, requiring robust security measures to prevent fraudulent activities during online assessments.

• Implement a secure, encrypted handshaking protocol between the main examination system and the security browser extension to prevent cheating attempts.
• Design and develop a browser lockdown add-on that disables opening new windows, copying/pasting, screen sharing, and access to other applications during exams.
• Ensure the system can launch security modules across multiple web pages dynamically with minimal code modifications.
• Achieve high system reliability and compatibility, avoiding virtualized environments where the security addon does not function properly.

• Secure handshaking mechanism utilizing encryption (e.g., BFECB mode) for communication between system and security add-on.
• Browser extension capable of disabling window opening, copy/paste functionality, screen sharing, and access to other applications during exam sessions.
• Ability to initialize and toggle lockdown features dynamically across multiple web pages.
• Self-study exam creation capabilities with detailed question explanations and multiple-choice formats.
• Compatibility with popular browsers and deployment on physical machines for testing.

• Encryption modules for secure communication
• Exam content management system
• User authentication and access control systems

• Encryption in BFECB mode with minimal latency to ensure real-time lockdown enforcement
• System must operate reliably on physical machines; virtualized environments are not supported
• Secure handling of cookies and encrypted tokens during handshake procedures
• Scalability to accommodate increased exam volumes without performance degradation

The implementation of a secure, browser-lockdown online examination platform is expected to significantly reduce cheating incidents, ensuring fair assessment. This system will enable the client to provide credible and objectively measured exam results, thereby enhancing reputability and maintaining compliance with examination integrity standards. It is projected to support large-scale deployment, improve exam security, and facilitate seamless, tamper-proof testing environments.
