摘要：Cloud computing has brought a new way that organizations store and manage their data, due to reduced cost, robustness and ubiquitous nature. It offers the promise of massive cost savings along with increased IT agility. But the storage and access of sensitive data in cloud computing is an important issue to consider. Still many organizations are not fully confident to have the benefits of the cloud, pointing problems regarding data loss and unauthorized access, and are reluctant to give faith on cloud providers to solve these challenges. This paper discusses some mechanisms and techniques which are used to preserve the privacy in cloud computing.
