Radius divergence optimized round hash index blockchain-based transaction-secured unified data in smart environment

In the guise of numerous mobile gadgets and IoT devices associated to the Internet a huge amount of data called, unified data structure is generated in different forms. With the intention of coping with the coercion of storing and assessing tremendous amounts of unified data both locally and globally, data owners generally store them in cloud servers. However, the data owner will lose control of this unified data and it will be at the fear of being vandalized with and deleted. To address on these issues, in this article, a Radius Divergence-optimized and Round Hash Index Blockchain-based (RD-RHIB) transaction-secured unified data is proposed. The RD-RHIB transaction-secured unified data model is split into two sections, namely optimization and transaction security. First, Shannon Information Radius Divergence-based Unified Storage Optimization is applied to the unified stored data to ensure optimal unified data storage for further analysis. Second, Round Hash Index Asymmetric Key Blockchain-based transaction security model is designed. To this end, unification employs blockchain ledger for efficiently transmitted access permissions that grant exchange of data instead of the transfer of data itself. Followed by which complicated mathematical problems are to be solved to group validated transactions into blocks and include them into blockchain ledger. Upon successful meeting of the conditions, transaction is said to be executed and recorded on the blockchain. A suite of experiments are validated and analyzed to verify the proposed RD-RHIB method’s service availability, reliability and scalability. According to the results of the performance analysis, our RD-RHIB method has the highest data confidentiality with an improvement of 38%, data integrity improvement of 28% when compared to other conventional methods.
