 When enterprises outsource their data to third-party cloud storage providers, they can save storage infrastructure investments and furthermore reduce administration costs tremendously. However data privacy and integrity are hindering their data migration steps to flexible and cost effective cloud storage. And traditional security schemes can provide data protection for this complicated cloud environment by sacrificing convenient operations, such as searching and sharing, which conflicts the flexibility and availability of cloud environment with multi-services for multi-tenants. This raises the demand for innovative and secure searching schemes to protect data privacy, data storage and retrieval process, and to access data flexibly on cloud storage. In this paper, we proposed a privacy preserved data sharing scheme on cloud storage to protect data privacy without sacrificing the cloud flexibility and accessibility: 1) Privacy Preserving Data Searching scheme to provide secure and efficient searching and sharing on privacy hidden data on cloud storage; 2) Policy based access control provides flexible yet data access ability on the privacy protected data.
