-\begin{abstract}
-Information hiding security is often expressed as a probability problem.
-However, various classes of attacks cannot currently be addressed,
-due to strong hypotheses not compatible with a probabilistic approach.
-In this work, a complementary theoretical framework is presented to
-improve security. Contrary to existing ones, it is not based
-on probability theory, but on mathematical topology.
-It addresses thus security issues in classes of
-attacks that are not currently studied.
-It can also be used to reinforce the
-confidence in a new scheme.
-In this paper, first the theoretical framework of the study is presented,
-then some concrete examples are detailed in order to show how our approach
-can be applied.

-\section{Chaos for Data Hiding Security}
-\label{section:Chaos}
-
-This section starts with a state of the art in chaos-based information hiding
-(Sec.~\ref{subsection:ChaosInComputerScience}).
-It reminds the readers of the theory of chaos as introduced by Devaney
-(Sec.~\ref{subsection:Devaney}).
-Other qualitative and quantitative properties are next introduced
-(Sec.~\ref{subsection:properties}).
-Their application to information hiding concludes this section (Sec.~\ref{subsection:links}).

-\section{Chaos-Security of two Data Hiding Schemes}
-\label{CS}
-
-To check whether an existing data hiding scheme is chaos-secure, we
-first write it as an iterate process $X^{n+1}=f(X^n)$
-defined on the set $\mathcal{X}$, with $X^0$ as the initial
-configuration of the machine.
-Let then $\mathcal{T}(S)$ be the iterative process of a data hiding scheme $S$
-and $\tau$ be a topology on the topological space $\mathcal{X}$.
-If $\mathcal{T}(S)$ has a chaotic behavior on $\mathcal{X}$,
-as defined by Devaney, $S$ is said
-to be \emph{chaos-secure} on $(\mathcal{X},\tau)$.
-
-This section studies two classes of
-data hiding schemes in the perspective
-of chaos theory.
