Trustworthy Blockchain Based Certificate Distribution for the Education System

Abstract

Due to increased mobility and growth in global students, as well as the current issue of diploma forgery and the sale of forged certificates, the storage and sharing of student educational records continues to present numerous privacy challenges. This paper proposes block chain-based decentralized certificate management systems in higher education. In this scheme, diploma management tasks like preserving, issuing, and verifying are implemented by the Proof of Work consensus algorithm. Encrypted data, keywords, and digital signatures are stored using cryptographic algorithms like (secure hash Algorithm) SHA-256 and (Elliptic Curve Digital Signature Algorithm) ECDSA. This system allows any individual student to be able to store and access educational certificates. College students can send their certificate hash value to verify their certificates so that organizations can verify the students' certificates using blockchain. Security and performance evaluations reveal that security and privacy preservation are possible with this proposed system. The proposed method is executed using Ethereum and the Solidity programming language. The proposed methodology can be employed by any university to tailor its education to the unique requirements of professional fields recognized by the industry's employers. Additionally, this method offers companies a platform where the employees' academic histories may be checked. This makes it simpler for students, organizations, and other sectors to get consent for student data.
