Abstract

This paper presents BlockAccess, a blockchain-based framework for secure and transparent access control in cloud data sharing. As organizations increasingly rely on multi-tenant cloud environments, traditional access control models fall short in ensuring traceability and trust. The proposed framework integrates smart contracts for dynamic access policy enforcement and uses a private Ethereum blockchain to maintain immutable logs of all data transactions. Experiments were conducted on simulated multi-user cloud scenarios, comparing BlockAccess to conventional Role-Based Access Control (RBAC) systems. The results show improved auditability, access transparency, and tamper resistance, with manageable overhead. This research demonstrates that blockchain can effectively decentralize access management and reduce unauthorized data exposure, offering a scalable and secure alternative to legacy systems in cloud computing.
