Abstract: P-sets(packet sets) are set pair combined with internal P-set XF (internal packet set XF) and outer P-set XF(outer packet set XF) , or(XF, XF) is P-sets. Dynamic P-sets are obtained by improving cantor set, dynamic characteristic of P-sets. I3y using the outer P-set XF，the concept of F-camoufladge carrier,F-camoufladge surplus were given. By using the concept,F- information camoufladge generation and F- information camoufladge structure were given,F- information camoufladge measure was given, F- information camoufladge ring theorem and F- information camoufladgering separation theorem,F- information camoufladge reduction theorem,F- information camoufladge identification were given. I3y using the results, the application of F- information camoufladge in information transfer was given. Information camoufladge is a new branch of studying information system.

Key words: P-sets, F- information camoufladge, Camoufladge measure, Camoufladge ring theorem, Reduction theorem, Camoufladge identification, Application
