Data deduplication is the important technique to eliminating the duplicate copies of repeated data in the cloud to reduce the storage space and save bandwidth in the cloud. Instead of taking number of similar files, it store only single copy of file. In several organizations,storage system contain many pieces of duplicate data. For instance, the same file may be stored in several different places by different users. Deduplication eliminates these extra copies by saving just one copy of the data and relocating the other copies with pointers that lead back to the original copy. It is data compression technique for bandwidth efficiency enhancing and storage usage.Data deduplication most widely used in cloud computing. It make the data management scalable & storage issue in cloud computing. Data deduplication assure the confidentiality of sensitive information.data deduplication works with convergent encryption technique to encrypt the data before uploading. Companies commonly use deduplication in backup and disaster recovery applications.In this paper we apply authorized deduplication check, together with convergent encryption for providing security to sensitive data using hybrid cloud computing.
