A novel secure aware privacy preserved data sharing framework in an E-government system based on a consortium blockchain

Electronic government (E-government) utilises information and communication techniques for delivering services to individuals. It is termed a complicated model that requires to be distributed, privacy-preserved and secured. The failure of these can lead to economic and social loss. The blockchain method facilitates the execution of a secured and privacy-preserved model wherein transactions are done securely. This paper presents a privacy-protected model for sharing of data in an e-governance system considering consortium blockchain. The proposed privacy-protected model involves eight different phases, namely initialisation, new node creation, delegates and witnesses voting, user registration, authentication, data protection, validation and data sharing. This method helps to facilitate the security of information and privacy and concurrently increases trust in the public sector. The proposed privacy-protected model provided enhanced performance with a small computational time of 40.422s and memory usage of 38.800MB
