An Autonomous Security Storage Solution for Data-Intensive Cooperative Cloud Computing

In order to reduce untrustworthy between cloud users and the underlying cloud storage platform, a novel cloud security storage solution is proposed based on autonomous data storage, management, and access control. The roles of users are re-evaluated, and the knowledge provided by the users is incorporated into the cloud storage model. Both the superiority of the public cloud in large scale data storage and the advantages of the private cloud in privacy preserving can be obtained. The main advantages of our approach include avoiding the superposition of complex security policies and overcoming the mistrust between the users and the platform. Furthermore, our security storage service can be easily integrated into the cooperative cloud computing environment. A prototype system is developed, and a use case is also presented.
