Cloud computing is an emerging technology which has been envisioned as the next generation information technology enterprise architecture. It manages application software and databases to centralized large data centers where the services may neglect to keep the files which are rarely accessed. This paper studies the problem of ensuring the integrity of user data stored in the cloud server. Here the author considers the task of allowing a Third Party Auditor (TPA), to check the integrity of data stored in the cloud on behalf of the cloud user.
