The inference problem is the major problem in securing the sensitive data in the secured database. In the inference problem the user tries to access the sensitive data from the secured database by giving series of queries with the non-sensitive fields. Inference problems affect the securities in the database and peculiarly in the Multilevel secure databases in which the data and users are differentiated into different levels. The authors' approach provides the control over the inference problems in the single as well as multi level database. They are provided with a trust based system which results in more efficiency when compare to the other techniques.
