A Three Layer Privacy Preserving Cloud Storage Scheme with FileDeduplication

Cloud computing has always been an inquisitive topic for discussion in terms of the recent computer science field. As the number of people using computer is increasing exceedingly at an exponential rate there is also a need to manage and store the data that is generated.These data has to be processed at a quicker rate .Cloud and fog are interconnected fog is closer to the end devices therefore more faster in terms of the response .As the number of users are growing exponentially the security for cloud also is of great importance. Data integrity of users using the cloud is of utmost importance. This work enlightens the importance as well as the proposed method for a secure data storage to safe guard and protect the users who store their data on cloud from unauthorized exploitation.
