Abstract: The widespread adoption of online examination systems has brought about significant challenges, including security vulnerabilities, data integrity issues, and concerns over fairness. Traditional systems often suffer from risks such as unauthorized access, data tampering, and manipulation of results, which undermine their trustworthiness. This paper proposes a novel blockchain-based online examination system that leverages decentralized ledger technology to create a secure, transparent, and tamper-proof examination environment. The system is designed with two primary modules: a student module for secure authentication and exam participation, and a teacher module for exam creation, monitoring, and result analysis. Facial recognition technology is integrated into the student module to ensure robust identity verification. By employing cryptographic hashing and custom block creation, the system guarantees data immutability and integrity. The proposed solution addresses the shortcomings of existing systems and offers a scalable, reliable, and secure platform for educational institutions.
