Abstract: Cloud computing provides resources sharing and to handling applications on internet without having local or personal devices. This paper strength the Proof of Retrievability model (PoR) of dynamic data integrity verification on distrusted and outsourced storages on cloud computing. The Outsourced Proof of Retrievability (OPoR) system focuses on cloud storage server for prevention of retune attacks and malicious operations of servers. In Public verifiability the security monitoring is taken by cloud audit server for reducing over head on clients. There is also need to strengthen the secure process of cloud audit server (CAS). This can be provided by generating unique temporary key for each update or modification of file from user. The reset attacks of CAS and cloud storage server (CSS) secure by unique temporary key and deleting the local host replica after verifying the uploaded proof tags of CAS and CSS. And reduce the cost of memory and process time using Elliptic curve cryptography The proposed system strengthening the proof of retrievability (SPoR) model will toughen the resistant of retrievability on upload and update of file operations on cloud computing.
