Third Party Auditing (TPA) For Secure Cloud Storage With Secret Sharing Algorithm

A scalable data storage service can be offered at a much lower cost by cloud storage providers. Users can be used cloud storage to remotely store there data. It will be helpful for the user to freed from extra load of storage space for data storage and manipulation of data but cloud storage also leads to invite the risk of no longer having physical possession of the data theft. Necessary efforts has been taken to build trust amongst use using different approaches for data security on cloud. Our main approach is also one step towards reducing this risk. In this approach access based privacy preserving authentication protocol (APPAP) is used. It will definitely address above privacy issue for cloud sharing and storage.
