Contact Tracing System
Do we really think this is the way to go?
The whole thing seemed like a big privacy issues to me initially, but some deeper analysis, Google/Apple's implementation is fairly reasonable from a privacy standpoint. Your phone would receive a code from everyone you come in close proximity to. If someone tests positive, they are added to the database of known infections, and your phone checks the database periodically and looks to see if you have been in proximity to anyone on the list during the time they were infected.
So, it isn't storing everywhere you went and everyone you came in contact with in some big database, although we know your phone company, Apple, google, Facebook, and everyone else seems to already have the location data and other countries are just using that to cross reference everyone for contact tracing.
Also, through some fun cryptography tricks, the code given to your phone can't be traced back to the individual, but when someone is added to the sick database, they add daily codes for the days they were infected. The daily codes can be used to determine if the codes your phone received are a match, but can't be used to identify the individual either as there is another layer of crypto to get back to the identifying code for the phone,
Finally, it appears the intent is for people to voluntarily identify as infected. Probably has to be that way because of medical privacy laws, but if we don't have most people voluntarily identifying, then it won't do much good.
