Also, I think that counting users by IP is still a fine way to do it (absent the privacy issue that PCSA tries to address). I was just stating that my understanding based on talking to the Tor Metrics people is that the plan is to handle the privacy issue by moving to per-connection country

Re: [tor-dev] Anonymous Local Count Statistics Using PCSA - GSoC

Sorry, I should have been more clear there. Tor Metrics estimates the total number of users by counting the number of directory downloads and dividing by an estimated expected number of directory downloads per user per day (10, I believe). This statistic is in the graph under the “Relay Users”

Re: [tor-dev] Anonymous Local Count Statistics Using PCSA - GSoC

Aaron, I think Jaskaran explained it well - basically, we compute statistics other than requests per country, and one of those stats is unique clients, which we can use PCSA for. The `format_client_stats_heartbeat` function in `/src/or/geoip.c` is where we actually compute the unique clients and

Re: [tor-dev] Anonymous Local Count Statistics Using PCSA - GSoC

Hi Aaron, These statistics not just tell about the user's country but also keep a track of unique IP addresses connecting from each country. This is needed so as to present more realistic stats. If we increment counter on any IP address instead of unique IP address then the statistics would also

Re: [tor-dev] Anonymous Local Count Statistics Using PCSA - GSoC

Hi Samir, It is my understanding that the Tor metrics team plans to handle this problem in a different way. IPs are kept in memory to provide statistics about users’ countries, and so they will instead just keep the country statistics directly. That is, a counter will be kept for all

Re: [tor-dev] Anonymous Local Count Statistics Using PCSA - GSoC

Hi Samir, this sounds like an interesting summer project. Since you are interested in using PCSA, our work on privacy-preserving statistics, which actually develops a privacy-enhanced version of PCSA, might be helpful. We also propose it as a way to collect distributed statistics. In our
