IMPORTANCE BASED SECURE STORAGE ENCRYPTED DATA DEDUPLICATION IN CLOUD

Abstract

Attribute-based encryption (ABE) has been wide utilised in cloud computing where data a information associate data provider outsources encrypted knowledge to a cloud service contribute, and that they are share the data with users possessing particular identification (or attributes). However, the standard ABE system doesn'tsupport secure deduplication, that's crucial for do away with duplicate copies of identical information therefore on avoid wasting house for storing and network metric. throughout this paper, we have a tendency to be apt to gift associate attribute-based storage system with secure deduplication in a very hybrid cloud setting, where a personal cloud is guilty for duplicate detection and a public cloud manages the storage. knowledge deduplication techniques check that that just one distinctive instance of data is maintained on storage of the cloud computing media, like disk, flash or tape.It is accustomed confidentially share information with users by specify access policies rather than sharing decodingkeys. it succeeds the standard notion of linguistics security for information confidentiality whereasexisting systems only succeed it by shaping a weaker security opinion. to boot, we have a tendency to tend to position forth a method to alter a ciphertext over one access policy into cipher text of identical plaintext but below totally different access policies whereas not informative the underlying plaintext.
