Main focus of database security research is maintaining data security and providing timely data services. Toensure security, inference attack and aggregate attack are the problems, which should be solved. But these will leavevolumes of data to discover some useful knowledge, and some data mining methods used in this field will bring forthsome positive or even negative results. In this paper, we survey what data mining has done on database security andpresent some open problems and possible future research directions.
Being an important part of Information System, Database Security has absorbed much attention fordecades. First, we bring forth the Database Security's contents, properties of data: sensitivity, integrity and availabil-ity. Several access control models to guarantee these properties are described in this paper. Due to the challengesbrought by advanced DBMSs such as OODBMS and ADBMS, we also discuss some security topics in these fields. Atthe end of this paper, the encryption control and inference control are reviewed together with some trend of thedatabase security technology in the future.
