Authorized Secure Deduplication in Cloud Computing

R. V. Argiddi | Prachi Sontakke

Abstract: A service model where data is provided to many users over the world, is called as Cloud storage. Data in this model is stored in several logical pools. Cloud storage is a concept of storage beyond an interface where the storage is controlled and managed on demand. This technology gives benefits by many features like data backup and archival, no need of maintaining hardware resources, greater data accessibility, etc. Data deduplication is an important feature in cloud storage. Deduplication process recognizes and gets rid of the repeated data in the backup storage, indirectly improving the network bandwidth. Providing security along with the deduplication process is a challenging task. In this paper, we survey the Ontologies related to deduplication techniques to give future direction. The key aspects used for maintaining security in cloud is convergent encryption. To overcome certain drawbacks in this encryption technique, we will describing new techniques- cryptographic tuning and domain separation. Maintaining the authorized access for the users confidential data, the concept called Proof of Ownership is used for recognizing the respective user along with his access privilege.
