Research Topic - Database Security

1) We started to work in Database Security in 2001. Security is critical to any computing system. We aim to focus on designing techniques to protect data/databases. We have focused on several aspects over the years, ranging from storage design (steganographic file systems) to securing data streams. In the past two years, we have studied data authentication in outsourced databases. Here, we focused on the completeness issue which has not been previously addressed in the literature. Essentially, we designed a scheme that enables users to verify that results obtained from third party publishers are complete without violating user access control. We are also the first to look at verifying multi-dimensional data.
