That is why, damage or loss of certificate is needed to be safe and, forge in graduation document must be prevented and secured as well. To overcome above drawback of paper certificate, this paper proposed to issue digital graduation document by utilizing blockchain technology as an enhancement of information security. In this work, we examine a basic understanding of what blockchain technology is and how it can achieve security with its immutability feature. Moreover, by using off-chain storage, digital graduation documents are no longer needs to be hosted the personal information on blockchain and computational performance become efficient.
