The increasing adoption of hybrid cloud environments presents new challenges for ensuring the security and privacy of sensitive data. This paper introduces the Encrypted Storage with Dynamic Reverse Hiding (ESDRH) algorithm, a novel approach designed to enhance hybrid cloud security through advanced reverse data hiding techniques for encrypted storage. The ESDRH algorithm encompasses four key components: Dynamic Key Generation (DKG), Adaptive Encryption (AE), Reverse Data Embedding (RDE), and Integrity Verification and Access Control (IVAC).Dynamic Key Generation (DKG) creates unique encryption keys for each data session, reducing the risk of key compromise. Adaptive Encryption (AE) combines symmetric and asymmetric encryption methods to optimize security and performance. Reverse Data Embedding (RDE) embeds unique identifiers and metadata within encrypted data blocks, ensuring data integrity and facilitating efficient management without compromising privacy. This technique allows for the secure distribution of encrypted data blocks across public and private cloud resources, enhancing both security and access efficiency. Integrity Verification and Access Control (IVAC) mechanisms are implemented to ensure that only authorized users can access the stored data, employing multi-factor authentication and continuous monitoring. Upon retrieval, data blocks are verified for integrity and decrypted, ensuring that the original content remains intact and accessible solely by legitimate users. The ESDRH algorithm offers a scalable, user-friendly solution to the complexities of data security in hybrid cloud environments, leveraging innovative reverse data hiding techniques to significantly improve data protection, compliance, and operational efficiency. This approach represents a substantial advancement in the secure management of encrypted storage in modern cloud infrastructures.
