The Exposure Notification FAQ: https://covid19-static.cdn-apple.com/applications/covid19/cu...

Relevant quote from the FAQ doc: There will be restrictions on the data that apps can collect when using the API, including not being able to request access to location services, and restrictions on how data can be used.

AFAIK in my jurisdiction the QR codes are a simple number, which the app reports along with the names of the people who have checked in or you are checking in. The number represents all the data that UK code is trying to convey. Not sure why the UK code needs all of that within itself rather than having a lookup table of some sort the number points to.

If the lookup table was stored on the server, requesting the data would effectively provide the user location to the central server. This is the part that isn't allowed. I suspect the lookup table is too big to store on the device itself.

Why would the app need to do a lookup? Store the numbers, and if/when you test positive then submit them along with your bluetooth keys.

Seems to me like a lot of these problems go away if governments stop making things more complicated than they need to be.

Well that's possible, but doesn't add any additional security and has the negative effect that users can't see where they have scanned into on their device (e.g. on the NHS app you can go to 'venue data' and see where you have logged into).

If one of your user stories involves users being able to see the names/addresses of venue's they have visited, you will either need to store the venue name in the QR code or do a lookup.

In this specific case, I'm really glad they're exercising their power, because they seem to be doing it in the best possible way, and have forced governments to do the right, privacy-preserving thing. And I think having this power is OK - nobody should be forced to help the government implement something unethical. There may be scenarios where this goes horribly wrong, but the contact tracing framework is a case wher…

> nobody should be forced to help the government implement something unethical Nobody is forced to install the app at all (at least in the UK's case). And if they do, they're not forced to share their location anyway. On the other hand, anyone who has an Android phone is forced to share tons of data with Google. And the cost of not having one is much higher than the cost of not having the government's app.

I'm talking about tech companies being forced to help governments distribute large scale mass surveillance tools.
