Multicloud storage systems have become integral for organizations seeking scalable and resilient data solutions. However, ensuring provably secure data possession in such distributed environments remains a critical challenge. This research addresses this concern through the integration of identity-based distribution techniques into multicloud storage architectures. We propose a novel system that leverages identity-based mechanisms to enhance the security of data possession, providing verifiable assurances to data owners. The paper presents a comprehensive analysis of the proposed system, evaluating its effectiveness in mitigating security threats inherent in multicloud storage. Experimental results demonstrate the robustness of the identity-based distribution approach, showcasing improved data possession security without compromising system performance. This work contributes to the ongoing discourse on secure data management in multicloud environments and opens avenues for further exploration in identity-based solutions for distributed storage systems.
