Abstract
To address these challenges, this paper proposes ExamShield, a hybrid blockchain-based examination system that ensures the integrity and security of exam processes. By integrating a Flask and SQLite backend with Ethereum smart contracts, the system stores cryptographic hashes of MCQs on the blockchain, making them tamper-proof. Additionally, dynamic question randomization using a candidate-specific paper hash and strict device fingerprinting help prevent collusion and unauthorized access, while maintaining efficient real-time performance.
