A Framework for Secured Access Control of Cloud Data Using Blockchain Technology

Abstract

Cloud computing provides a scalable storage, but ensuring data security and access control are still challenging areas of research. The present work proposes an efficient framework for secure access control of cloud data using blockchain technology. The framework leverages blockchain’s decentralized nature to enhance trust and transparency. Smart contracts automate access control, policy for ensuring access of authorized users. Cryptographic technique is used to secure data transmission and storage. The system eliminates reliance on third-party entities, reducing vulnerabilities. Experimental results show improved performance in terms of security and access efficiency. The computed results are presented in the form of table and graph.
