Cloud Security threats have greatly hindered the development of Cloud Computing and the promotion of cloud application, so how to protect the data stored in the cloud is not only the core issue of security, but also the biggest challenge of development. As these problems above, a trust-control architecture based on the concept of Cloud Storage Service was creatively proposed. Based on the structured strategy and isolated distributed storage-framework, the architecture of cloud services can eliminate the concerns about cloud security and achieve a high degree of safe, reliable and available cloud storage. It’s rather a simple and efficient way proved by experiments.
