+Other steganalysers than the ones used in this document will be
 examined for the sake of completeness. Finally, the
 systematic replacement of all the LSBs of edges by binary digits provided
 by the BBS generator will be investigated, and the consequences of such a 
 replacement, in terms of security, will be discussed.
+Furthermore, we plan to investigate information hiding on other models, high frequency for JPEG encoding for instance.
