Tor Anomaly Detection
Rewrite & Demo Visualization
Select a country from the drop down to get started.
Click on a green or red dot in a graph to get links to possible censorship events on that date.
This is a
new interactive data-visualization
of the Tor projects
anomaly-based censorship-detection system.
I took on this side-project after hearing that multiple statisticians had attempted to update the code, but had given up because the
existing code-base was complex and badly documented.
I focused on making the existing code cleaner and comprehensively documented. I used the high-performance data analysis library pandas in the rewrite which speed up the data analysis considerably and allowed me to integrate previously external “preparation” scripts written in R directly into the code.
