Data deduplication or intelligent compression is a method for eliminating duplicate copies of redundant data, and has been widely used in cloud services to decrease the amount of storage space and upload bandwidth. Sometimes we have to store duplicate data in cloud storage for confirmed data retrieval during critical situation, in other words to implement fault tolerance mechanism. This proposed system addresses Authenticated Deduplication with Security measures. In this system all users are having their own privilege and the user who is uploading the file for the first time can fix the Access Privilege and Deduplication Privilege. Based on these setting other users can access the file as well as check if the same file is already uploaded. This system uses Hybrid cloud approach to provide better security. All the files uploaded into the cloud have to undergo two processes. First is the Encryption process for data Security and next is the Tag Generation Process to identify the file presence in the cloud. In this system all the keys with privilege are stored in Private Cloud server and encrypted data is stored in Public Cloud.
