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 identical copies of repeating data and it is used in the cloud storage for the purpose of reduce the storage space as well as save bandwidth. To retain the confidentiality of sensitive data while supporting the deduplication, to encrypt the data before outsourcing convergent encryption technique has been proposed . This project makes the first attempt to formally address the problem of authorized data deduplication giving better protect data security, Different from the traditional deduplication system, distinctive benefits of the user are further considered the duplicate check besides the data itself. Hybrid cloud architecture having various new deduplication constructions supporting authorized duplicate check. The proposed security models contain the illustration of security analysis scheme. As a proof of concept, contains the implementation framework of proposed authorized duplicate check scheme and conduct experiments using these prototype. In proposed system contain authorized duplicate check scheme sustain minimal overhead compared to normal operations.
