In order to update k-anonymous and confidential database, the suppression based and generalization based updating protocol technique has been proposed.These protocols check whether the database inserted with the new tuple is still k -anonymous without knowing the content of the table and database respectively.But these methods will not work if initial database is empty.Also, if the incoming tuple that fails the test of these updating protocols, there is no solution for which action to be taken.So, in this paper we propose two solutions based on pending tuple set (i.e. a collection of all tuples that fails anonymous property of database) namely the private extraction of k-anonymous part of pending tuple set or kanonymization of pending tuple set by privately suppressing entries.
