Now-a-days, the authors can outsource data backups offsite to third-party cloud storage services (Jelastic cloud) by which they can reduce data management costs. However, they need to provide security guarantees for the outsourced data, maintained by third parties. In this paper, they design and implement FADE, a secure overlay cloud storage system which is able to achieve fine-grained, policy-based access control and file assured deletion. It associates the outsourced files with file access policies, and assuredly deletes files to make them unrecoverable by anyone upon revocations of file access policies.
