Cloud computing offers a brand new approach of service provision by re-arranging numerous resources over the web. The most important and widespread cloud service is information storage. So as to preserve the privacy of information holders, information square measure usually hold on in cloud in associate degree encrypted kind. However, encrypted information introduces new challenges for cloud information deduplication that becomes crucial for large information storage and process in cloud. Ancient deduplication schemes cannot work on encrypted information. Existing solutions of encrypted data deduplication suffer from security weakness. They can't flexibly support information access management and revocation. Therefore, few of them may be without delay deployed in follow. During this paper, we tend to propose a theme to deduplicate encrypted information hold on in cloud supported ownership challenge and proxy re-encryption. It integrates cloud information deduplication with access management. We tend to valuate its performance based on in depth analysis and pc simulations. The results show the superior potency and effectiveness of the theme for potential sensible readying, particularly for large information deduplication in cloud storage
