  This is a common misconception about what's happening. Google and Apple aren't jointly releasing a contact tracing app. They're creating an API that public health apps can use. Which means you still need to figure out a way to get people to download a 3rd party app. Very hard. ht…

• @moxie Moxie Marlinspike on x

  Second caveat is that it seems likely location data would have to be combined with what the device framework gives you. Published keys are 16 bytes, one for each day. If moderate numbers of smartphone users are infected in any given week, that's 100s of MBs for all phones to DL.

• @moxie Moxie Marlinspike on x

  All that aside, these APIs are novel in terms of what becomes possible from the app layer. I'm not super optimistic about opt-in contact tracing becoming a major factor, but I do kind of anticipate that someone will end up using this for some other interesting thing.

• @moxie Moxie Marlinspike on x

  3) Your device keeps track of all “proximity IDs” it sees. 4) If someone tests positive, they choose to publish their (previously secretly) “daily tracing keys.” 5) Your device frequently DLs all published daily tracing keys and KDFs to see if they match recorded proximity IDs.

  Just today, I wrote about why Bluetooth-based contact tracing is a flawed solution. - Hard to get population-wide adoption. Singapore managed to get 12%. - BLE data collection is not granular to the level of 6 feet. Can lead to many false positives. https://www.theverge.com/...

  There's been a lot of writing recently about the use of apps to help us track exposure to COVID-19. I talked to public health experts this week who explained why they're unlikely to be effective https://www.getrevue.co/... https://twitter.com/...
