| Summary: | 碩士 === 國立交通大學 === 資訊工程研究所 === 83 === Most access control mechanisms state views as access control
objects. These mechanisms consult permissions tables to
determine whether a query should be allowed. Access control
mechanisms cannot prevent individuals from inferring
unauthorized information, and therefore, we proposes an
inference control model. This inference control model analyzes
a given set of views to determine the information that a user
can infer,thereby preventing disclosure of unauthorized
information.
