We propose to develop a design for a reliable distributed relational database management system to safeguard sensitive information. Each day, increasingly more highly sophisticated computer attacks are occurring in the information storage systems of financial institutions, eCommerce businesses, universities, hospitals and government agencies. We urgently need to develop a secure and dependable way to safeguard our information repositories and storage systems. In this research, we propose to develop a highly robust, dependable and secure relational database management system to prevent sensitive information from being lost, stolen or corrupted. The basic idea is to (i) include a (k, n) threshold-based secret sharing scheme (k ≤ n) to provide privacy and durability in order to prevent sensitive information from being lost or stolen, (ii) incorporate an efficient distributed database management design to enhance system performance and minimize interfered accesses contentions, and (iii) integrate private information storage (PIS) schemes to reduce communication overhead and improve robustness of the system.
