S-rough sets (singular rough sets) have three forms: one direction S-rough sets (one direction singular rough sets), the dual of one direction S-rough sets (dual of one direction singular rough sets), and two direction S-rough sets(two direction singular rough sets). S-rough sets have dynamic characteristics, genetic characteristics, memorial characteristics and hiding characteristics. By using S-rough sets, the concepts of f-hiding knowledge, F-hiding knowledge, hiding degree and dependence degree were presented, hiding theorem and dependence theorem of hiding knowledge were proposed, and the applications of hiding knowledge were given.
