Description

A sensor network is a group of specialized transducers with a communications infrastructure for monitoring and recording conditions at diverse locations. Cloud computing has been envisioned as the next generation architecture of the IT enterprise due to its long list of unprecedented advantages: on-demand self-service, ubiquitous network access. In proposed system, the system proposes a new cloud storage scheme in proof of retrievable for cloud storage, in which a trustworthy audit server is introduced to preprocess and upload the data on behalf of the clients. On the other side we improve the semi-honest trust worthy and ensure dynamic data process in cloud. And This system develops a strengthened security model for considering data security against data leakage attack in cloud and the storage server in the upload phase of an integrity verification scheme. And presents an efficient verification scheme for ensuring remote data integrity in cloud storage.
