报告摘要：

With the advent of Big Data, there has been a rising trend of outsourcing data management to cloud service providers, which provide query services to clients on behalf of data owners. While the cloud model is appealing in terms of scalability, elasticity and self-manageability, it brings about new challenges to query processing. In particular, the service provider can be untrustworthy or compromised, thereby returning incorrect or incomplete query results to clients, intentionally or not. Therefore, empowering clients to authenticate query results is imperative for outsourced databases. In this talk, we will start by a review of representative query authentication techniques. Then, we will present some of our recent efforts on authenticated query processing with privacy preservation requirements and in multi-source settings. We will also discuss some possible future research directions.
