\chapter{Landmark Privacy} \label{ch:lmdk-prv} In this chapter, we propose a novel configurable privacy scheme, \emph{\thething} privacy, which takes into account significant events (\emph{\thethings}) in the time series and allocates the available privacy budget accordingly. We propose two privacy models that guarantee {\thething} privacy. To further enhance our privacy method, and protect the {\thethings} position in the time series, we propose techniques to perturb the initial {\thethings} set (Section~\ref{sec:theotherthing}). \input{problem/thething/main} \input{problem/theotherthing/main} \input{problem/summary}
