Cloud computing enables highly scalable services to be easily consumed over the Internet on an as needed basis. A major feature of the cloud services is that users' data are usually processed remotely in unknown machines that users do not own or operate. In this paper, the authors address the construction of an efficient PDP scheme for distributed cloud storage to support the scalability of service and data migration, in which they consider the existence of multiple cloud service providers to cooperatively store and maintain the clients' data. Offering strong data protection to cloud users while enabling rich applications is a challenging task.
