Downgrade Delegated Proof of Stake Based Consortium Block Chain Espoused Anonymous and Traceable Group Data Sharing in Cloud Computing

Abstract

Group data sharing is a crucial aspect of cloud computing, enabling collaborative work and information exchange among multiple entities. However, ensuring secure and efficient data sharing within a group presents various challenges. In this manuscript, Downgrade Delegated Proof of Stake based Consortium Block Chain espoused Anonymous and Traceable Group Data Sharing in Cloud Computing (DDPS-BC-ATGDS-CC) is proposed. In this manuscript, the block chain technique uses every user in the system to rapidly and simply authenticate the shared data validity without interacting with a third-party auditor. Utilizing Downgrade Delegated Proof of Stake based consortium block chain (DDPS-BC),in construction database, which is tamper-resistant and maintained by all participants, stores the verification info for auditing. The performance metrics, like accuracy, Computation of traceability and Computation of data sharing are examined. The performance of the proposed DDPS-BC-ATGDS-CC technique provides 25.28%, 36.45%and 32.20% greater accuracy compared with the existing techniques like Secure and effective data sharing among vehicles based on consortium block chain (SEDS-BC-CC) , trusted data sharing with flexible access control based on block chain (TDS-FAC-BC)  and an Accountable privacy-preserving scheme for public information sharing systems (APPS-PISS-CC).
