Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Databases are increasingly being used to store information covered by heterogeneous policies, which require support for access control with great flexibility. This has led to increasing interest in using fine-grained access control, where different cells in a relation may be governed by different access control rules. Although several proposals have been made to support fine-grained access control, there currently does not exist a formal notion of correctness regarding the query ansring procedure. ,  propose such a formal notion of correctness in fine-grained database access control, and discuss why existing approaches fall short in some circumstances.  then propose a labeling approach for masking unauthorized information and a query evaluation algorithm which better supports fine-grained access control. Finally,  implement our algorithm using query modification and evaluate its performance.
