Abstract: Data deduplication is a data storage saving method which has been used in cloud servers for deleting duplicate data files. It stores only one copy of the identical data file on the cloud server instead of storing number of similar data files and offers their users infinite storage space. On cloud servers, most of times users save the same data files, so same data files take huge space. Repetitious copies of data files prevented by deduplication and retain one copy of the data files. It works with encryption technique to provide security to data files before uploading to cloud server. The Cost of storing and transferring data can be greatly reduced by data deduplication. The intention of this paper is to address the problem of authorized data duplicate check and analyse security of stored sensitive data using hybrid cloud architecture which made up of public cloud and private cloud. Data confidentiality is strengthened by this hybrid cloud arrangement .Thus users protect the sensitive data and outsourced to the cloud storage securely.
