A Private Blockchain-based Distributed Ledger Storage Structure for Enhancing Data Security of Academic Documents

Initially the Blockchain technology was used to implement different digital currencies. Nowadays blockchain is adopted as a common technology to be used in various business applications. Blockchain based solutions have underlying features like security, tamper proof, transparency and consensus. Apart from that, history of data can be maintained on a blockchain network that can be retrieved from any place and at any time. Blockchain provides immutability which is a solution to avoid faking of certificates. This Paper presents a blockchain based solution to issue certificates and prevent fake certification by using digital signature to enhance the data security long with proof of validity smart contract is used to access the blockchain network with valid key. The proposed permissioned blockchain based academic certificate repository system provides and manages degree certificates as assets for educational institutes. Academic certificates and e-certificates can be securely shared and distributed by students and learning institutes through this application.
