In present cloud storage services integrity became major problem. For these traditional researchers implemented so many approaches, but still its facing major problem of security and data owners storing data in multiple clouds. The authors implemented the security of their scheme based on zero-knowledge proof system and which can satisfy completeness and knowledge soundness and zero-knowledge properties. The performance optimization mechanisms for their scheme and in particular present an efficient method for selecting optimal parameter values to minimize the computation costs of clients and storage service providers.
