Blockchain E-Certificate System with Ethereum Network and IPFS

The certificate system is essential for academic organizations to provide proof of study or the level of skills and education. However, simply providing a physical cert or a virtual cert can be easily forged, and it will be difficult to be verified and authenticated. Many techniques are proposed to protect certificate’s authenticity such as Digital Watermarking Technology, RSA Digital Signature. Furthermore, there are also Blockchain approaches such as integration of existing system and private blockchain. However, those systems have weaknesses such as the vulnerability to be cracked and efficiency in verification of the certificate. The aim of this research is to provide a system that is capable of securing certificate authenticity from activities of certificate fraud. In this research, we proposed a blockchain e-certificate system for academic organization and public to issue and verify e-certificate with a simple web-based user interface. By combining the advantages of using decentralized ledger for key information and utilize IPFS to store the certificate file, it can solve the problem of the vulnerability of the existing system.
