DESCRIPTION: \nThe Web has evolved into a complex ecosystem -- visiting on
 e website may actually involve a large number of other third party domains
  such as advertisers and analytics companies\, which place cookies in our 
 browsers. Many of these third parties are present on several common websit
 es\, and are therefore able to track users' visits across websites and gai
 n visibility into their browsing patterns. We have created a browser exten
 sion that helps users understand how their privacy may be compromised by t
 hird parties. Over 2000 users across the world have deployed this extensio
 n\, of whom 565 users have shared their data with us. Based on this\, we p
 resent an analysis of the current state of privacy on the Web in 65 differ
 ent countries. We find\, for example\, that Chinese users fare better than
  users in countries like UK\, US and Canada. We also develop a metric call
 ed `tangle factor'\, to quantify the interconnectedness of independent fir
 st party websites\, and use this to measure and compare the efficacy of di
 fferent privacy measures (e.g.\, ad blockers). Finally\, we examine the im
 pact of GDPR and find that this does not seem to have had an appreciable i
 mpact\, perhaps because users are choosing default suggestions for allowed
  cookies.\n\nBio: Nishanth Sastry is a Professor of Computer Science at Th
