A block chain-based approach using proof of continuous work consensus algorithm to secure the educational records

Nowadays, academic records are converted into digital form, but there are two major challenges that remain unresolved. First is achieving secure and reliable academic record storage; second is recognising academic record sharing and confirming the security of sharing process. In this research work, Proof of Continuous Work (PoCW) consensus algorithm fostered blockchain (BC) system is proposed for securing students educational records (PoCW-BC-SSED). It consists of three process, institutions joining process, blockchain-enabled secure data storage and blockchain-enabled secure data sharing. For institution joining procedure, new institution tries to link the BC network to create its public along with private keys. BC-Enabled Secure Data Storage is based on PoCW blockchain algorithm. The academic records are maintained in independent data centres of the institutions as well as shared with other universities as part of the BC-Enabled Secure Information Sharing process. The shared data is kept on file in BC. The proposed method protects the records on the storage server with maximal security and reliability using consistency check protocol. The proposed method is executed using Ethereum. The efficiency of proposed method is estimated with the help of several performances metrics.The proposed method attains 19.67%, 22.38%, 27.45% higher accuracy; 28.92%, 25.83%, 19.46% higher precision while compared with existing methods such as BC-based approach with academic information protected storage and transmission scheme(EduRSS-BC-SSED), blockchain-based models for securing student information systems that develops the highly trusted ledger for storing the vital information(MOOC-BC-SSED) and BC base proof of work approach for developing the trust in ubiquitous higher education(BC-PoW-SSED) respectively.
