Moving user data on cloud provides convenience
and avoids the complexity and hardware management for the
user. However, the cloud concept brings many challenges
which influence the system on various factors such as
usability, security, reliability, scalability and overall system
performance. User who is storing the data on cloud server
has to check the integrity of the data which becomes an
overhead every time. This task is outsourced to another
public auditor. These parties may not be trustworthy. To
mitigate this possibility and to alleviate the integrity checking
and computation overhead we proposed a system. Proposed
system does the integrity checking and preserves the privacy
of the data from the Third Party Auditor.

This paper describes importance of the cloud for storage,
challenges in using cloud as storage and prior works to
solve those challenges. Paper addressed the lack of privacy
preservation in existing system and proposed a system
which provides Public Integrity verification, Privacy from
public auditor and cloud storage server, Dynamic Data
modification.
