An Improved Algorithm for Hiding Sensitive Association Rules Using Exact Approach

Many algorithms are proposed by researchers to find association rules which help the users to make strategic decisions to improve the performance of the business or any qualitative organizations. The threat occurs to association rule mining when data or information is required to share to many users to get mutual benefits. Among the existing techniques the exact hiding approaches provides best solutions with minimum side effects. A modified inline algorithm is proposed in this paper to hide sensitive rules by formulating constraint satisfaction problem without any side effects with the concepts of positive and negative border sets. By adopting divide and conquer technique on constraints, the efficiency of the proposed algorithm is increased.
