CLOUD STORAGE DE-DUPLICATION AND ENCRYPTION

Joshi Vinay Kumarmr, V Ravi Shankar

Abstract: De-duplication is one of the latest trend technologies in the current market because of its ability to reduce costs. But it comes in many different indication and organizations need to understand each one of them if they are to choose the one that is best for them. De-duplication can be applied to data on primary storage, backup storage, cloud storage, LAN and WAN transfers.Organizations frequently use de-duplication in backup and calamity recovery applications as well to avoid duplicate of similar data for savage of space in cloud.In this paper we attempt Data de-duplicationcombined with methods of implementing de-duplication, HASH BASED DE-duplication,Erasure Code, Threshold Proxy Re-encryption technique.

Keywords: de-deuplication; erasure code;threshold re-encryption technique; homomorphism; hash based DE duplication
