摘要：Life has been incredibly busy. Therefore the need for data gradually increases over the time. Users require data to be stored somewhere and retrieved easily, whenever needed. Taking these factors into consideration the concept of cloud is now from the fact. It had been the place where one can store the data of different varieties and could be retrieved at any place, at any time. Also, it provides services to its users which include Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). It substantially becomes effective to a large extent in serving clients, thanks to its properties such as scalability, flexibility, transparency, cost saving ability and eco-friendliness. Each technology had been enforced for making life easier, they’ll continuously persist some problems that had to be delineated with. The technology of cloud also had such issues. The field of cloud computing had been facing the issues associated with data integrity such as replaces, replay and forge attack. The continuous need had emerged out for solving such problems, to keep original user data intact. The proposed system presents a Third Party Auditor (TPA) that could solve these issues by shouldering transparency. The paper discusses methods such as Simple Auditing and Dynamic Auditing for solving above mentioned problems. Both the methods use the Tag Generation technique for doing auditing. TPA neither supports Cloud Service Provider nor did Data Owner hence act as monitoring agent. Auditing is carried through logical operations, without a single copy of an original data, to maintain confidentiality. It takes its auditing decisions based on the generated results providing opportunity to Cloud Service Provider, for improving Cloud’s services. Auditor warns data owner about prohibited activities of Cloud, boosting the quality of the services. The methods of this paper help in improving auditing services to some extent, along with the above mentioned issues related to data integrity.
