Cloud computing has emerged as a popular model in computing world to support processing large volumetric data using clusters of commodity computers. It is the latest effort in delivering computing resources as a service. It is used to describe both a platform and a type of application. A cloud computing platform dynamically provisions, configures, and deprovisions servers as needed. Cloud computing also describes applications that are extended to be accessible through the Internet. Data security and access control is one of the most challenging ongoing research work in cloud computing, because of users outsourcing their sensitive data to cloud providers.
