Ethereum-Based Certificate Creation and Verification Using Blockchain

Abstract

Certificates are signals of achievement or membership. A web-based system for secure verification of academic certificates and a blockchain system for storing academic weblogs are proposed in this paper. Certificates are created digitally using QR and search to find the certificate from the database. Any modification in the certificate can be identified by the Base64 image comparison. The environment is less complex to design because hyperledger is not a coin (“token”) based blockchain. A transaction on hyperledger does not require a virtual currency transfer, in contrast to bitcoin or Ethereum. The application has two main components: Webserver and Ethereum. The disadvantage of storing information on a blockchain-based application is that it cannot store image files; instead, it uses weblogs for storage. When proposing a digital way of handling certificates, give utmost importance to how it eliminates counterfeit certificates from the system. Making such a digital system will eventually lead to questions regarding the security of the digital content (i.e.) certificates. To ensure that the digital certificates are stored in a secure way such that a malicious attacker or a user cannot change the content of these certificates. When a member tries to exploit the system and make sure that they are removed from the system without causing much damage to the overall functioning of the system. The proposed digitally created certificate can be verified by anyone with high security.
