Cloud computing is a new computing model which enables individuals and organizations to gain access to huge computing resources without capital investment. It does mean that users can utilize computing resources in pay per use fashion. With virtualization technology the commoditization of computing resources has become a reality. The world is experiencing the advantages of cloud computing as industry giants like Microsoft, Google, Amazon etc. are providing cloud computing services. However, the cloud environment is considered in trusted as it is accessed through Internet. Therefore people have security concerns on data storage security of cloud computing. Many techniques have been proposed in the literature for ensuring data storage security in cloud computing. This paper presents the details of three most recent techniques that came into existence to protect clients data stored in cloud. The empirical results of these papers proved that they are effective and can be used in real time cloud computing.
