QUESTION PAPER LEAKAGE PROTECTION USING BLOCKCHAIN

Abstract: Question paper leakage has emerged as a serious challenge in modern educational systems, undermining the credibility of examinations, creating unfair academic outcomes, and eroding public trust in assessment processes. Traditional paper distribution methods, often centralized and lacking robust safeguards, are highly susceptible to insider threats, data tampering, and unauthorized access. To address these vulnerabilities, this project proposes a blockchain‑based solution that leverages decentralization, immutability, cryptographic encryption, and smart contracts to securely manage question papers. The system ensures that all papers are encrypted, stored in a tamper‑proof distributed ledger, and made accessible only through time‑locked, identity‑verified mechanisms. Every access attempt and distribution event is recorded immutably, providing full traceability and eliminating the possibility of undetected leaks. By combining strong security mechanisms with transparent audit trails, the proposed platform not only prevents question paper leakage but also restores examination credibility, minimizes manual handling, and offers a scalable framework for secure academic operations.
