摘要：Cloud computing have brought great convenience for data sharing and data storage. The large no. of participants are sharing data in cloud. security issues like integrity, efficiency and privacy of the user should maintained while sharing the data in cloud. In cloud storage services, managing data is a major challenge as data is increasing continuously. For the management of data, deduplication is a well - known technique of data compression to remove duplicate copies of data in storage over a cloud. Data deduplication provides lot of benefits in cloud for security and privacy of data. Deduplication highly used in cloud storage to minimize storage space. In traditional deduplication used convergence encryption which provides confidentiality but do not check duplicates with some differential privileges. In this paper secured deduplication implemented to prot ect data security with differential privileges of user. The files are encrypted with differential privilege keys to provide robust security. Only the marked files are allowed to duplicate check by the user. The third party auditor can audit the data and ve rify the users presence of file deduplication in cloud. Auditor audits and verifies the uploaded file on a time .This paper useful for user and storage provider by auditing technique and deduplication technique respectively
