Enhancing the Security of Statistical Databases with a Question-Answering System and a Kernel Design
Gültekin Özsoyoğlu, Francis Y. L. Chin · IEEE Transactions on Software Engineering · 1982
The security problem of a statistical database is to limit database use so that no private information is deducible. This paper discusses the advantages of using a Question-Answering System and a security kernel to enhance the security constraints at the conceptual model level. An SDB design with the goal of helping the DBA in specifying certain security contraints is proposed.
