+Tracking methods have been actively researched in the past. Survey papers
+commonly focus on one aspect of the tracking ecosystem.
+\citet{mayerThirdPartyWebTracking2012} focus on third party tracking and policy
+surrounding this issue. \citet{cahnEmpiricalStudyWeb2016} and
+\citet{englehardtCookiesThatGive2015} research cookies and their impact on
+privacy online. \citet{chaabaneBigFriendWatching2012} focus on how social
+networks are able to track users.
+\citet{roesnerDetectingDefendingThirdparty2012} study the tracking ecosystem and
+potential defenses built into the browser. \citet{belloroKnowWhatYou2018}
+discuss new methods and the extent to which they are used for tracking purposes.
+\citet{schelterUbiquityWebTracking2016},
+\citet{englehardtOnlineTracking1MillionSite2016} and
+\citet{gonzalezCookieRecipeUntangling2017} perform a large-scale analysis of
+third party tracking using one million and more web sites.
+\citet{papadopoulosCookieSynchronizationEverything2019} are concerned with
+cookie synchronization and its impact on tracking on the web.
+
+\citet{yuTrackingTrackers2016} survey popular browser addons for their tracking
+protection capabilities and \citet{xuUCognitoPrivateBrowsing2015} focus on the
+private browsing mode implemented by most modern browsers. Because browsers
+often do not provide the necessary protection,
+\citet{vlajicAnonymityTORUsers2017} take a closer look at the Tor Network and
+Browser. \citet{merzdovnikBlockMeIf2017} are concerned with blocking tools such
+as \emph{AdblockPlus} as defense against tracking on the Internet.

-  abstract = {Many anonymous communication networks (ACNs) with different privacy goals have been developed. Still, there are no accepted formal definitions of privacy goals, and ACNs often define their goals ad hoc. However, the formal definition of privacy goals benefits the understanding and comparison of different flavors of privacy and, as a result, the improvement of ACNs. In this paper, we work towards defining and comparing privacy goals by formalizing them as privacy notions and identifying their building blocks. For any pair of notions we prove whether one is strictly stronger, and, if so, which. Hence, we are able to present a complete hierarchy. Using this rigorous comparison between notions, we revise inconsistencies between the existing works and improve the understanding of privacy goals.},
