System for Secure Storage and Auditing of Cloud Data

Cloud computing is compilation of existing technique and technologies, packaged within a new infrastructure paradigm that offers improved scalability, elasticity, business agility, faster startup time, reduced management costs, and just-in-time availability of resources. Cloud computing is an Internet-based computing and use of computer technology which provides access to resources as a service such as storage, network, server and processors etc. By moving data into the cloud offers great ease to users. In general, data center in cloud holds information that users have stored on their computers. The security concerns arises because the outsourced data is used by the user. Cloud computing is the growing field now a days. The platform provides help to reduce the cost as well as make the effective utilization of the hardware as well as software. Data storage is the main most desirable aspect of the cloud computing, but it comes with some security challenges too. The end users store their data on cloud server are always in worry that either their data stored is secure or not As the data stored is large enough so users can not check its integrity periodically. Sometimes cloud service providers may behave unhonestly and delete customers data Or they fail to make changes on the data which is updated by the users frequently. So to overcome these challenges the Trusted Third Party Auditor plays the vital role on behalf of customers. As they assure to customers that the data hosted on the server is secure. TPA provides more easier and affordable way for users to their storage correctness in cloud, which also helpful for the cloud service providers to improve their cloud based service platform. In other way we can say auditing scheme play a significant role in establishment of secure cloud platform in users mind and increase the cloud economy, where users accesses the risk and apply their trust in the cloud to store data more precisely.
