Hi Tom

I thought the requirement was a 40% take-up of the app.

Yes. I tried to keep a previous post short but there is no reason the app can 
not be fully accessible for scrutiny if it periodically polls a secure server 
for new anonymous IDs. There is no secret squirrel stuff in the app itself.

The legislation only needs to define security requirements on the announcement 
server and who has authority to release anonymous IDs to that server. Nothing 
more.

With that transparency, I'd install the app and I'm sure others could be 
encouraged to as well. If the app was installed on 90% of phones and 
effectiveness (false positives or missed contacts in Bernard's post) was even 
say 50% wouldn't that still achieve the 40% figure above?

My thought was that this moves the tracking app from surveillance architecture 
to a human centered design.

All the best
