Abstract: Most of the IT industry heading towards the cloud –based storage services .cloud storage is witnessed to weak in security and privacy for public cloud environments .To tackle these security challenges ,we propose a new deduplication at client side for secure data storing and data sharing among the cloud users through public cloud .our proposal is mainly concerned on the owner of the file is encrypted the data that he intended to upload to the cloud by applying per data key, so data access controlled by data owner and log file which contains retrieval rights of the cloud users ,an authorised user can decipher an encrypted file with his private key.

Keywords: convergent encryption, cloud storage, deduplication, privacy, Merkle-tree
