        abstract = {Cloud storage has become an important part of modern data management, but security and privacy concerns remain critical challenges. Traditional cloud security mechanisms rely on centralized models, making them vulnerable to single points of failure, insider attacks, and unauthorized access. To address these challenges, this paper present a Decentralized Multi-layer Security Framework that integrates Hyperledger Fabric and Homomorphic Encryption to enhance the confidentiality, integrity, and availability of cloud-stored data.
The proposed framework leverages Hyperledger Fabric, a permissioned blockchain, to decentralize access control, enforce security policies through smart contracts, and ensure tamper-proof auditability. Simultaneously, Homomorphic Encryption allowing computation on encrypted data without decryption, preserving data privacy even during processing. The multilayer security approach combines blockchain-based identity management, cryptographic access control, and encrypted computation to mitigate risks such as unauthorized data breaches, collusion attacks, and malicious modifications. Experimental results demonstrate the framework’s efficiency in reducing latency while maintaining high security standards. Performance evaluations show that the approach outperforms conventional cloud security models in terms of data confidentiality, integrity verification, and resistance to insider threats. The proposed solution provides a scalable and practical safety model for safe cloud storage in domains like healthcare, finance, and IoT.},
