Re: A Moment of Silence #Foremembrance Today, TraceTogether

Folks,

First I am happy to see some positive insights coming from this 
discussion after the initial sniping.  Thanks @joe for comments 
regarding taxation and identity.

I live in Singapore and use the TraceTogether app.  It is opt-in and 
decentralised.  The contact data is only stored on the owner's device, 
in encrypted form.  According to design and packet sniffing by testers, 
there is no beacon or phone home capability.

I'm not aware of any actual trace backs done yet - the app was only 
launched a week ago.  But in theory the way it works is the owner of the 
device grants permission to the MOH to decrypt the data, which reveals a 
list of phone numbers.  At that point, either these are correlated with 
other tracing data or used by MOH to make direct contact with 
individuals possibly exposed to Coronavirus.  Keep in mind that those 
contacted would have already opted in to the application and sharing of 
data.

Asians are generally quite acquiescent to such disclosures provided they 
trust the counterparty, even where there have been data breaches in the 
past.  Government and telcos are widely trusted in Singapore.
