Role Based Encryption with Efficient Access Control in Cloud Storage

Cloud is nothing but the platform where large amount of data can be stored virtually. As the concept says that cloud provide many types of services to the users. Extra resources can be extended virtually so that there is no need to fix any extra resource physically. For example, there is no need to bring the extra RAM for dedicated server. In this concept if hybrid cloud is used. So that, better authentication can be provided. Owner can outsource data to the cloud by attaching policies to that data. Role manager is responsible for adding and revoking roles of a particular user. Admin works as a central authority to the private cloud. Like this admin is responsible for verifying the integrity of data which is stored in the cloud. This system provides better access control because of the hybrid cloud concept.
