Chain-based big data access control infrastructure

Technological advancements have brought about the rise of data and other digital assets in our world today. The major problems with data today are its security and management, more importantly access control. These factors when not tackled effectively can lead to many compromises. The blockchain is an effective technology that ensures utmost security, trust, and maximum access control in big data systems. However, almost all the transactions on a blockchain network are stored in the platform. This process reduces the data storage, as the storage of all transactions sometimes creates unnecessary overheads. In this paper, an off-chain-based sovereign blockchain is proposed, where a virtual container is created for parties to transact in. At the end of a transaction, and satisfying each party, the container is destroyed but the results are stored on the sovereign blockchain network. This effectively decreases the amount of data that would have been stored on the network. The effectiveness of our system is compared with other schemes, and we could infer that our proposed system outperforms the already-existing ones.
