Secure Multi-Cloud Storage Architecture Using Blockchain Technology
Abstract
Data security and trust management remain major concerns in multi-cloud environments. This paper introduces a blockchain-enabled secure storage architecture for multi-cloud systems. The proposed framework integrates distributed ledger technology with encryption mechanisms to provide secure data sharing, integrity verification, and decentralized access control. Smart contracts automate authentication and permission management among cloud users and providers. Results indicate improved transparency, resistance against data tampering, and enhanced reliability compared to conventional cloud security models. The study highlights the potential of blockchain in strengthening future cloud storage ecosystems.
