Cloud computing offers a replacement approach of service provision by re-arranging various resources over the net. the foremost necessary and well-liked cloud service is information storage. so as to preserve the privacy of information holders, data are often hold on in cloud in associate encrypted type. However, encrypted information introduce new challenges for cloud information deduplication, that becomes crucial for giant information storage and process in cloud. ancient deduplication schemes cannot work on encrypted information. Existing solutions of encrypted information deduplication suffer from security weakness. they can't flexibly support information access management and revocation. Therefore, few of them is promptly deployed in apply. during this paper, we propose a theme to deduplication encrypted information hold on in cloud supported ownership challenge and proxy re-encryption. It integrates cloud information deduplication with access management. we have a tendency to judge its performance supported in depth analysis and pc simulations. The results show the superior potency and effectiveness of the theme for potential sensible readying, particularly for giant information deduplication in cloud storage.
