    To verify the data integrity and third party auditor at user side in cloud computing
    (Central University of Punjab, 2014) Goyal, Renuka; Sidhu, Navjoot
    Now-a-days the concept of Cloud Computing is one of the major theories in the world of IT. Its services are now being applied to several IT scenarios. Cloud Computing is the Internet based computing which provides users with a number of services. One of the services provided by the cloud computing is data storage. Users store their data in the cloud without the burden of local data storage. But as every technology has some drawbacks, cloud computing also has some drawbacks. The main drawback of cloud computing is the security issues that are associated with it. The security issue with which this dissertation is dealing is the threat to data integrity. As the user no longer has physical possession of data so the integrity of data stored on cloud server become the major concern in the cloud computing. Data stored on the cloud server may be getting corrupted and sometimes even the cloud service provider for his own benefit like for more space on data centre can discard the user data which is not used for a longer time. In order to maintain the integrity of data, the user takes the assistance of a Third Party Auditor (TPA). The Third Party Auditor checks the integrity of data on user demand and the released audit reports not only helps the user to evaluate the risk of their services but also helps the cloud service provider to improve their security mechanism. As a part of verification it is assumed that Third Party Auditor is reliable and independent which does not mean that there is no space for the Third Party Auditor to cheat. So there is need to check the integrity and Third Party Auditor at user side. This dissertation highlights the basics of cloud computing, general model and different approaches used for Third Party Auditor. The model to verify the data integrity and Third Party Auditor is implemented in this dissertation and the results found are good according to the user data.
