Limiting Disclosure of Sensitive Attribute Values: An Active Approach

As computer and other technologies advance and various data and information are pervasively available, preservation of private information embedded in volume data are facing more and more challenges than ever before. Although there are available mechanisms in database management systems limiting access to some sensitive and private information, some inference techniques might still be able to bypass the access control mechanisms to acquire these unauthorized information inappropriately. This paper will propose an active approach to limiting disclosure of sensitive and private information.
