A Flexible Database Security System Using Multiple Access Control Policies
TLDR
We propose a database security system that can individually control user access to data groups of various sizes and is suitable for the situation where a user's access privilege to arbitrary data is changed frequently. Expand

Decision Tree Classifier for Multiple Abstraction Levels of Data
TLDR
This paper shows that multiple abstraction levels of data can cause undesirable effects in decision tree classification. Expand
Database Security System supporting Access Control for Various Sizes of Data Groups
TLDR
We propose a database security system that can individually control user access to data groups of various sites and is suitable for the situation where the user`s access privilege to arbitrary data is changed frequently. Expand
A Flexible Database Security System using Improved Role Hierarchy
Decision Trees for Multiple Abstraction Levels of Data
TLDR
The proposed method accommodates the generalization/specialization relationship between data values in both of the construction and the class assignment phases of decision tree classification. Expand
A flexible database security system using multiple access control policies
Due to various requirements for user access control to large databases in hospitals and banks, database security has been emphasized. There are many security models for database systems using a wide… Expand
