Implement Security using smart card on Cloud

Cloud is a concept of accessing the data from their own datacenters such that the chances of eavesdropping have been reduced and storage cost is reduced. Here in this paper we are giving a brief survey of various cloud based technique implemented so far. A lthough there are various techniques implemented so far for the cloud computing but here we are giving a survey of not only cloud based techniques but also the concept of smart cards for the authentication between one cloud to another cloud.
