We will try -to take into account the least significant bits too during all the -stages of the algorithm, hoping by doing so to be closer to the HUGO scores against -steganalyzers. Other steganalyzers 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. - \bibliographystyle{plain} \bibliography{biblio}
