Abstract: Trust is the biggest concern in the services provided by cloud computing. Data is completely outsourced and processed on the remote machines. Data owner could be as ingle user or organization that owns the outsourced data. Risk increases due to unknown locations and machines storing and processing the data, No physical control and no information about the processing entities decreases the confidence of data owner in cloud computing. Issues like data distribution, data access, and data management over vulnerable paths lack mechanism in the favour of the data owner.There is no such mechanism which allows the data owner to sense & control the privacy of data. The threat also increases when data is replicated at a number of machines. We are trying to improve the trust by launching improved integrity algorithms. That will increase the confidence of data owner on the cloud with the inclusion of the external entity, which is providing the assurance of security auditing and preventing the unauthorized use of data. Our experimental results are derived from the comparison of possible existing solutions.
