      A thread about fear of surveillance in times of COVID-19: A lot of the discussion seems weird to me. The cellphone companies have your (tower) location data, and people with unfettered access to SS7 do, too. Foreign SIGINT has this data (telco networks are prime targets...

      ...while not being terribly well-defended). The advertising giants have much more granular data to help sell you more cruises. Odds are that your free fitness tracker app sells this data, or leaves it in an open S3 bucket.

      If you live in a free democracy, granting access of this data *provided* the WHO has declared pandemic status (and not otherwise) poses little political risk in non-pandemic times - a single gov can't force the WHO.

      I have no idea whether geolocation-based contact tracing is helpful, but a lot of the worriers about surveillance seem willfully ignorant of all the data that is already collected AND monetized. It shows how much society is in denial about the loss of privacy since...

          The current state of privacy has long since entered the "we have to rely on legal limits of use" territory. The "if it's collected, it will be seen by every bad actor and all of everyone's worst fears will be de facto realized" mentality is unproductive at best, harmful at worst

          There is a far cry of difference between "cell phone companies have it" and "feds have it for increasingly arbitrary purposes". Because things can always get worse when authorities have increasingly unfettered access to location info.

          We have looked at this question, and to the best of our knowledge, absolute geolocation data (cell triangulation or GPS) is not useful for contact tracing. It is too inaccurate and has relatively large error margins on top. Bluetooth and/or ultrasound *may* work.

          And above the question on effectiveness, absolute location data is simply not needed if contact tracing is the goal. You care about who you met, not where you met them. Record the proper data (relative proximity) for the question, and not anything more.

          on the „will it help“ question, I found the below paper interesting. also contains references to previous work on manual contact tracing:https://github.com/BDI-pathogens/covid-19_instant_tracing …

          The flaw in your arguments is that you pretend there's only one way forward, that more surveillance is inevitable. I am not using free fitness trackers, try to prevent ad tracking as much as possible and am thankful for everyone fighting for more privacy in the digital realm. ->

          Should privacy advocates stop criticising further expansion of tracking and stop.fighting against the existing methods? Raising the general level of privacy for anyone should be the goal instead of giving in to further erosion of rights, just backed by broken present conditions.
