Improving Performance of Efficient Data Dynamics in STaaS using FMT
N Sridhar Babu · 2014
Storage as a Service (STaaS) is the service offered by cloud computing over the Internet where user data is stored and maintained remotely without the burden of local data storage and maintenance. However, the users will no longer have physical possession of the outsourced data brings new challenge towards the integrity of the data. The introduction of TPA eliminates the involvement of the client through the auditing of whether his data stored in the cloud are indeed intact. Moreover, user frequently wants to update the data they store. The support for data dynamics via the most general forms of data operation, such as data insertion, deletion and modification is also very important, since services in Cloud Computing are not just store static files. Experimental a nalysis shows how to construct an elegant verification scheme which preserves privacy. To achieve efficient data dynamics, the existing storage models is manipulated by using the Fractal tree traversal technique. The Fractal tree construction and traversal greatly improves the performance of data dynamics where user’s time taken to insert, update and delete the content of the file is reduced significantly.
