 rff dimension - Ryabko\, D. (INRIA\, Lille\, France)

DESCRIPTION:It was shown recently that the limit capacity of perfect stega
 nography\nsystems for i.i.d. and Markov sources equals the Shannon entropy
  of\nthe ``cover'' process. Here we address the problem of limit capacity\
 nof general perfect steganographic systems.  We show that this value\nasym
 ptotically equals the Hausdorff dimension of the set of possible\ncover me
 ssages.\n
