Abstract: Cloud computing is the long dreamed vision of computing as a utility. Besides all the benefits of the cloud computing security of the stored data need to be considered while storing sensitive data on cloud. Cloud users cannot rely only on cloud service provider for security of their sensitive data stored on cloud.  To achieve optimal usage of storage resources, many cloud storage providers perform de-duplication, which exploits data redundancy and avoids storing duplicated data from multiple users. System proposes a new approach to achieve more efficient deduplication for (encrypted) large files. Our approach, named Block-Level Message-Locked Encryption (BL-MLE), can achieve file-level and block-level deduplication, block key management, and proof of ownership simultaneously using a small set of metadata. The  BL-MLE method can be simply completed to hold confirmation of storage, that  makes it multi-purpose for secure cloud storage.

Keywords: Third Party Authenticator, AES Algorithm, RSA Algorithm, SHA 512 Algorithm, deduplication, Block-Level Message-Locked Encryption.
