Cloud computing is a promising computing model that enables convenient and on-demand network access to a shared pool of configurable computing resources. In cloud computing, data owners host their data on cloud servers and data consumers can access the data from cloud servers. This new paradigm of data storage service also introduces new security challenges, because data owners and data servers have different identities and different business interests. Therefore, an independent auditing

Moreover copyright protection is not provided. In this paper, we define specially a provable data possession model for multimedia file, and present a framework based on digital watermarking for multimedia data storages audit service, in which we analyze the security features of audit service for multimedia data outsourcing and the corresponding properties of digital watermarking. Moreover as an example, we present a provable data possession scheme based on double function self-embedded digital watermark, which integrate image content audit service and copyright protection. We define specially a PDP model for multimedia file, and present a framework based on digital watermarking for multimedia data storage audit service: Defining the security features of audit service for multimedia data outsourcing and the corresponding properties of digital watermarking. We propose a special provable data possession scheme based on multi-function digital watermark, which integrate image content audit service and copyright protection through a double function self-embedded watermarking scheme. It is worth noting that the presented scheme is very efficient compared with the previous PDP schemes, since only watermarking is required.
