The last decade has seen the rising of cloud computing and storage services. With a small cost or even free, data owners can simply upload their databases to a cloud and let it manage the data and process queries on their behalf. By releasing data owners from day-to-day management of software and hardware, cloud services have the potential to save them significant operation cost. Data owners, however, are facing with difficulty in fully trusting cloud services. After all, the data is in the hand of a third party that is beyond their own dministrative domain. A cloud may be compromised by outside hackers or corrupted by malicious insiders, thus sending users wrong answers, unintentionally or intentionally. In this talk, we discuss the challenges of enabling users to verify the query results they received from a cloud is indeed correct and present a number of solutions.
