A Complexity Approach for Steganalysis
  In this proposal for the Journ\`ees Codes et St\'eganographie 2012, we define a new rigorous approach for steganalysis based on the complexity theory. It is similar to the definitions of security that can be found for hash functions, PRNG, and so on. We propose here a notion of \emph{secure hiding} and we give a first secure hiding scheme.
