Anatomy of the Third-Party Web Tracking Ecosystem
The presence of third-party tracking on websites has become customary.
However, our understanding of the third-party ecosystem is still very
rudimentary. We examine third-party trackers from a geographical perspective,
observing the third-party tracking ecosystem from 29 countries across the
globe. When examining the data by region (North America, South America, Europe,
East Asia, Middle East, and Oceania), we observe significant geographical
variation between regions and countries within regions. We find trackers that
focus on specific regions and countries, and some that are hosted in countries
outside their expected target tracking domain. Given the differences in
regulatory regimes between jurisdictions, we believe this analysis sheds light
on the geographical properties of this ecosystem and on the problems that these
may pose to our ability to track and manage the different data silos that now
store personal data about us all

IOT Network Behaviours and Dependencies
Many current claims suggest that many of these sources will arise from deployment of off-the-shelf Internet-of-Things (IoT) sensors in buildings and infrastructure at scale. In this paper we take an early look at some baseline data gathered from a set of such sen- sors. We perform some simple analysis of the types and rates of data these sensors will generate and distribute, the supporting ser- vices they will invoke, and the resulting infrastructure dependen- cies they take. We consider a wide range of sensors from environ- mental sensors (e.g., temperature, CO2) to some more immediately sensitive sensors (e.g., video cameras).IoT infrastructure, Scalabilit
