Securing University Diploma Management through Blockchain and InterPlanetary File System

Abstract

The pervasive issue of degree fraud poses a signif-icant challenge to the credibility of academic credentials, neces-sitating innovative solutions to ensure the integrity of diploma verification processes. This paper proposes an integrated solution leveraging Blockchain, InterPlanetary File System (IPFS), and Advanced Encryption Standard (AES) encryption technologies to establish a secure and transparent diploma management system. IPFS offers a decentralized approach to file storage and distribution, eliminating reliance on centralized authorities and enhancing data availability and accessibility. Similarly, Blockchain technology provides a tamper-resistant ledger for storing diploma data, ensuring transparency and immutability through distributed consensus mechanisms. Ethereum, with its smart contract functionality, facilitates the automation of trans-actional processes, further enhancing the system's efficiency and reliability, finally, AES ensures the confidentiality of certificate contents through strong encryption, preventing unauthorized access to sensitive information. The loading process for university diplomas involves encrypting PDF files with AES encryption, uploading them to the IPFS cluster, and recording their unique hash values on the Ethereum blockchain. Subsequently, the verification process requires accurate specification of both the file and transaction hash values, ensuring the authenticity of diplomas through blockchain-based verification. The implemen-tation of the proposed system demonstrates its efficacy in securely uploading and verifying diplomas, utilizing technologies such as MetaMask for Ethereum authentication and AES encryption for data confidentiality. By ensuring the integrity and authenticity of diplomas, the system mitigates the risk of fraud and upholds the integrity of educational qualifications.
