Abstract

In a multilevel secure database management system, users cleared at different security levels access and share a database with data at different sensitivity levels. A serious threat to database security, not adequately addressed at present, is the inference problem. That is users acquire unauthorized information from the responses that they legitimately receive. It is the inferencing capability and deductive power of intelligent database systems that could provide viable approaches for handling the inference problem. The author describes secure query processing in intelligent database systems. The types of database systems that are considered are augmented relational systems, fuzzy relational systems and object-oriented systems
