Abstract
Fine Grained Access Control (FGAC) provides a row-level security mechanism that's built-in to the Oracle database engine. FGAC allows to granularly specifying the exact information elements that each user may access. Several proposals have been made for fine grained access control which has resulted in information leakage and redundancy of a query. So we have proposed a query evaluation algorithm which supports fine grained access control. There are several models for fine grained access control but major of them follow a view replacement model in which these two problems occur. First is the redundancy of data as data is masked from one level to other second is leakage of information through the error and exception message. In our paper we have proposed our own algorithm for the disclosure policy of data residing in the database that avoids the leakage of information and controls the redundancy of data.
