Enhanced Data Security in Cloud Computing with Third Party Auditor
Cloud computing is environment which enables convenient, efficient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Cloud is kind of centralized database where many organizations/clients store their data, retrieve data and possibly modify data. Cloud is a model where user is provided services by CSP (Cloud Service Provider) on pay per user base. Means here Client has to pay for what he is using or being served. Data stored and retrieved in such a way may not be fully trustworthy so here concept of TPA (Third Party Auditor) is used.
