A Survey On: Secure Data Deduplication on Hybrid Cloud Storage Architecture

Abstract

Data deduplication is one of the most important Data compression techniques used for to removing the duplicate copies of repeating data and it is widely used in the cloud storage for the purpose of reduce the storage space and save bandwidth. To keep the confidentiality of sensitive data while supporting the deduplication, to encrypt the data before outsourcing convergent encryption technique has been proposed .To better protect data security, this project makes the first attempt to formally address the problem of authorized data deduplication .Different from the traditional deduplication system, differential benefits of the user are further considered the duplicate check besides the data itself. Hybrid cloud architecture contains several new deduplication constructions supporting authorized duplicate check. The proposed security models contain the demonstration of security analysis scheme. As a proof of concept, contains the implementation framework of proposed authorized duplicate check scheme and conduct testbed experiments using these prototype. In proposed system contain authorized duplicate check scheme incurs minimal overhead compared to normal operations.

Different Secure Data Deduplication Approaches for Cloud Storage: A Review

“…After the information encryption and key age process clients hold the keys and send the cipher text to the cloud. Since the encryption activity is determinative and is gotten from the information content, comparable information duplicates will produce the same united key and thus the same cipher text [4]. Presently a day's cloud turns into an appealing pattern toward the general population.…”
