A Secure and Adaptable Framework for Decentralized Cloud Storage by Fusion of RDH-EI and Blockchain

Abstract

The primary objective of this research is to investigate the seamless fusion of RDH-EI and blockchain, capitalizing on the inherent strengths of both paradigms. By integrating blockchain into the RDH-EI framework, a distributed ledger system is established, ensuring the confidentiality, integrity, and traceability of embedded data. The integration also introduces a decentralized governance structure through smart contracts, empowering fine-grained control over data access within the decentralized cloud storage environment. Innovatively, this research introduces dynamic parameter adaptation within the RDH-EI process, leveraging blockchain consensus mechanisms to optimize embedding parameters in real-time. This dynamic adjustment accommodates variations in network conditions and evolving security requirements, enhancing the adaptability of the embedding process. The envisioned contributions of this research include a fortified security posture for RDH-EI applications in decentralized cloud storage, dynamic adaptability of embedding parameters, a decentralized key management system, and cross-dataset generalization through extensive evaluations. As the research unfolds, it not only addresses the contemporary challenges of secure multimedia data embedding but also provides a forward-looking perspective, offering a robust and adaptable solution for the evolving landscape of decentralized cloud storage ecosystems. The outcome of this research is anticipated to shape the future of secure and efficient data embedding in the rapidly advancing domain of decentralized cloud storage.
