Apple and Google Are Launching a Joint COVID-19 Tracing Tool (techcrunch.com) 80

Posted by msmash from the how-about-that dept.
Engineering teams at Apple and Google have banded together to create a decentralized contact tracing tool that will help individuals determine whether they have been exposed to someone with COVID-19. From a report: Contact tracing is a useful tool that helps public health authorities track the spread of the disease and inform the potentially exposed so that they can get tested. It does this by identifying and 'following up with' people who have come into contact with a COVID-19 affected person. The first phase of the project is an API that public health agencies can integrate into their own apps. The next phase is a system level contact tracing system that will work across iOS and Android devices on an opt-in basis. The system uses on-board radios on your device to transmit an anonymous ID over short ranges -- using Bluetooth beaconing. Servers relay your last 14 days of rotating IDs to other devices which search for a match. A match is determined based on a threshold of time spent and distance maintained between two devices.

            Both Google and Apple passively track where you are constantly, it's in their privacy policies, for similar reasons. The most obvious thing they use this for is traffic data. Ever wondered how Google knows there's a traffic jam? Because it sees a whole lot of phones moving slowly down the road.

            They also track you for "Internet of Things" reasons: both iOS and Android allow you to run IoT presets based on your current location. How do they know where you are? They track you.

          • unless you leave your GPS on. You would notice the battery drain if they were. Now, if you leave your GPS on then yes, they are probably tracking you. You have to turn off a lot of the Map features to avoid being tracked while the GPS is turned on.

            Personally getting free GPS software in exchange for my privacy is worth it. There are much, much easier ways to oppress me than tracking my movements.

That polling data is archived and make it very easy for historical location of the device with very good accuracy. The data transferred by polling contains signal strength and quality data for all or servers polling the mobile address and that's just a simple example.

      You may want to read the protocol specification first :-)

      - Location is not tracked, only proximity to others
      - Your proximity history never leaves your phone, only some keys do in case you are tested positive

      If this is done right, all privacy-critical data remains on your phone.

      PS: Of course one may argue that there might be more going on behind the scenes. But in that case I wonder why people with that kind of reasoning do use a smartphone at all

      • Location is not tracked, only proximity to others

        A distinction without a difference. I believe the majority of users have enabled location on their phones, and if I'm tracked as "in proximity" with user X whose location is known, then my location is known. And I don't believe for a minute that Google will let a tool that lets them add tracking for the black sheep that disable location on their phones just fall by the wayside...

          A distinction without a difference. I believe the majority of users have enabled location on their phones, and if I'm tracked as "in proximity" with user X whose location is known, then my location is known.

          Read the published specification. For that matter, read the post you replied to: "Your proximity history never leaves your phone". That means no one gets it, not Google, not anyone else.

      • Yes. Oddly the "if you test positive" prerequisite for sending the data to a server is missing in the summary.

        I had considered starting my own log of position whenever I went out so that I could hand it over if I happen to test positive at some point, but this seems better. (I have google position history turned off and have google play services denied position access on my phone. I would be using OsmAnd for the position log, the openstreetmap client for android.)

      From TFA, location data is not used. Data is not even shared unless you opt-in a second time to do so. The only data used is randomized 'keys' of other phones you have been near. That data is then just published as "the owner of this device has it." Your phone checks the list and tells you, "hey, we were near that person on this day for X minutes." Because of that, it won't help in the contaminated doorknob case.

        • You don't understand the nature of how "tracking" using Anonymous data is still not anonymous at all. Given enough "random" anonymous data, a profile can be built that does indeed reveal specifics.

          Yes, all from Anonymous Sources.

          And that's a problem. It isn't one source, it is all of them together. Digital Fingerprint of my phone is unique, and links directly back to me, eventually. The fact that it looks innocuous at first glance gives false sense of security.

      The only data collected is a set of randomly-generated keys, not linked to any account or device, and those keys are only collected (by the local health authority, not Apple or Google) when someone who has tested positive voluntarily provides them. Then the collected keys are distributed to all other users of the app, which allows their app to look through its own logs and determine if values derived from those keys were ever received via BLE. If so, the app of the undiagnosed user knows that they were in

No options look attractive.

Will you pay an extra 10% of your income to cover vaccine research, universal healthcare, quarantines for people who may or may not be sick, etc, etc?

        The app is actually very careful about your privacy. Unless you test positive and authorize the release of the information, it never does anything other than collect a local database of BLE-beaconed values, as well as transmit your own beaconed values for other devices to collect. The values change every 10 minutes (+- a fuzz factor) in lockstep with your bluetooth MAC address.
