+Equivalently, it can also measure uncertainty in information, and has thus 
 plenty of application in security and cryptography.
+We will cover the basic theory of information theory --- entropy --- and its 
+possible applications towards privacy.

+In particular, after this session you should be able to

+  \item \emph{analyse} relevant situations using entropy and information gain 
+    to yield insights into security and privacy.
+\end{itemize}
 
 The concept of entropy, the main part of information theory, is treated in 
-a few short texts: \citetitle{Eckersley2010apo}~\cite{Eckersley2010apo} and
