Certificate Verification System Using Blockchain

The large number of counterfeit certificates in circulation is a huge problem that has been prevalent for a long time. Issuing of such certificates has become a business stemming from the need/want of the people for employment. Hard working people with legitimate degrees/certificates have to suffer the consequences of this phenomenon since they are denied what could have been theirs by the holders of these fake credentials. It a lot of cases this can prove extremely dangerous for example, consider a surgeon operating on the basis of a fake degree. It is situations like these that highlight the need for a system which can provide verification and authentication of the certificates, its issuer and the holder. In this paper, leveraging the tamperproof and non-repudiation property of blockchain, we propose and implement a certificate issuing and verifying model.
