Cloud storage is one of the important services provided by cloud computing. It helps cloud users to overcome the drawback of limited resources usage, so that they can increase their storage capacity without enhancing their devices. In order to ensure the privacy and security to the data user, data is encrypted before uploading it in cloud. If we store a encrypted data in the cloud it consume more storage space. It is a difficult task to share encrypted data among the authorized users. Many schemes have been introduced to manage the storage space and access to the encrypted data in the cloud. The existing Heterogeneous Data Storage Management (HDSM) scheme introduced a authorized party with data owner to manage the data access control based on their interest. There is no option to add a new user to access for the file already exists in cloud. This process cannot achieve deduplication process and security efficiently. To address the limitations of the existing scheme a Dynamic Data Access Control and Secure Deduplication in Cloud (DDACSDC) has been proposed that provides dynamic data access permission to the new data user by verifying them based on their request. This new technique helps to improve system efficiency by performing better data deduplication process, minimize the cloud storage space utilization and reduce the data uploading time. To make system more secure and maintain data privacy Identity-based Proxy Re-encryption Scheme (IB-PRE). The performance analysis shows that the proposed scheme provides better security and improves system efficiency as compared to the existing scheme.
