With the growing popularity of cloud computing, more and more enterprises and individuals tend to store their sensitive data on the cloud in order to reduce the cost of data management. However, new security and privacy challenges arise when the data stored in the cloud due to the loss of data control by the data owner. This paper focuses on the techniques of verifiable data storage and secure data deduplication. We firstly summarize and classify the state-of-the-art research on cloud data storage mechanism. Then, we present some potential research directions for secure data outsourcing.
