This paper applies a divide-and-conquer approach to achieve confidentiality control in Cloud Computing. We sketch how a Redundant Array of Independent Net-storages (RAIN) for Cloud Computing can be designed using techniques originally intended for other purposes. The RAIN approach splits data into segments and distributes segments onto multiple providers. By keeping the relationships between the distributed segments private, the original data cannot be re-assembled. Further, with each segment small enough, each segment discloses no meaningful information to others. Hence RAIN is able to ensure the confidentiality of data stored on clouds.
