Abstract—Protecting confidential examination question papers is a major challenge for educational institutions, especially when digital systems are used for storage and access. This paper presents the Secure Paper System, a web-based application developed to improve the security of question paper management through multi-layered authentication and blockchain support. The system combines email-based One-Time Password (OTP) verification with MetaMask wallet authentication so that only verified and authorized users are allowed to access sensitive content.

After successful OTP validation using Node.js and Nodemailer, the user is required to connect a blockchain wallet to complete the second level of authentication. Question papers are encrypted before storage and uploaded securely to the InterPlanetary File System (IPFS). Important details such as the IPFS hash, authorized wallet address, and access conditions are maintained through smart contracts deployed on a blockchain network. This design helps ensure tamper resistance, controlled access, and improved data integrity.

The backend of the system is implemented using Express.js, while the frontend is developed with HTML, CSS, and JavaScript to provide a simple and user-friendly interface. By combining OTP-based verification with blockchain-enabled protection, the proposed system reduces the risk of unauthorized access and offers a practical security solution for handling confidential examination data.
