Abstract

Data deduplication is one of the hottest technologies in storage right now because it enables companies to save a lot of money on storage costs to store the data and on the bandwidth costs to move the data when replicating it offsite for DR. This is great news for cloud providers, because if you store less, you need less hardware. Data deduplication is one of important data compression techniques for eliminating duplicate copies of repeating data, and has been widely used in cloud storage to reduce the amount of storage space and save bandwidth. To protect the confidentiality of sensitive data while supporting deduplication, the convergent encryption technique has been proposed to encrypt the data before outsourcing. Different from traditional deduplication systems, the differential privileges of users are further considered in duplicate check besides the data itself. Whenever the cloud users upload a file to server. While sending files if it is duplicating the server will popup it is duplication message. This access is done in private cloud key generation, the deduplicate checker system will check the file names, file format, file content and file capacity and it will compare whether it is same or matching the uploading file from the exiting file in cloud server. The stored files should be encrypted after uploaded to the cloud server and are decrypted upon the client’s request. Only public users need the key for decryption while the private user does not. The encryption algorithm provides data confidentiality and authentication to the cloud server
