Secure Academic Credential Management using Blockchain-Based Self-Sovereign Identity

Digital identity management and verification of educational credentials have grown increasingly difficult in today's

times. Conventional practices tend to include centralized systems that are vulnerable to breaches and inefficiencies. Realizing the

existing difficulties in identity management, we suggest a decentralized SSI-enabled model to overcome these difficulties. The

model facilitates SSI-enabled operations such as user sign-up, issuing decentralized identifiers (DIDs) with public/private keys

created upon sign-up, issuing and creation of verifiable credentials (VCs) in the form of digital certificates of student

information, academic records, and issuer signatures and credential validation facilitated by decentralized blockchain-based

ledger. Educational institutions issue and create verifiable credentials associated with students ID. The system enables learners

to obtain and hold verifiable credentials (VCs) for their digital proof of certificate. The issued credentials would be retained offchain and hash value of the credential would be maintained in blockchain ledger. The model uses cryptography such as hashing

and digital signature to check data integrity and authenticity and issuance of the credential, storing and verifying will be handled

by Smart Contract. An easy-to-use interface that provides management, request, and document verification. An integrated system

based on blockchain, decentralized storage, and cryptographic algorithms ensures a privacy-oriented and consistent system for

handling academic documents.
