+We use the matrices $\hat{H}$
+generated by the integers given
+in table~\ref{table:matrices:H}
+as introduced in~\cite{FillerJF11}, since these ones have experimentally
+be proven to have the best modification efficiency.
+For instance if the rate between the size of message and the size of the host is
+1/4, each number in $\{81, 95, 107, 121\}$ is translated into a binary number
+and each one consitutes thus an column of $\hat{H}$.
