Decentralization of Credential Verification System using Blockchain

Abstract

After successful completion of graduation, students receive the credits of the courses in the form of certificate issued by the respective University. A Student have to produce his/her documents to the employers or the authorities for employment or higher education. Today ,as the system is centralized all the data resides on the server which can be hacked or the data can be lost if the system crushes down. However, verifying a certificate by authorities, is a time-consuming process as there is an involvement of human resources ,for validating the details of the candidate from its University. Today , with the advancement in technologies and due to the easy availability of many efficient soft wares that have led to the forgery of credentials/certificates. The lack of anti-tampering mechanisms resulted in incidents where the forged graduation certificates are often found. Also ,in case certificates are out of place , applying for duplicate certificates and its issuance by the University consumes a lot of time. Use of blockchain technology in this process will make the system decentralized as blocks as cryptographically connected and all the nodes in the network shares the entire chain .Hence the proposed decentralized certificate verification system, uses blockchain technology incorporating all the essential features in developing a DAPP. This system is proposed to address the issue of certificate counterfeiting, faster certificate verification and issuance. Putting across all the issues, the system aims at addressing the problems and provide solutions to the current Certificate Issuance, verification and Validation Process.
