I don't think such a list would be that long:
1. It's not unreasonable to have some approximate concept of location (e.g. "New York City and surroundings")
2. A contract tracing app is only useful when the number of new infections is low enough, such that all possible contacts can be tested.
3. For a tracing key 32 bytes would suffice. Even for 15,000 relevant infections you're only looking at 0.5 MB of data.
- donarb 7y agoThe "location" data would be self size limiting since its based on the users who are using the app provided by a local public health agency, like a city or county.
- rburhum 7y agoThanks for the answer. Now, I am not sure your tracing key gets updated as far as I understood. Isn't the individual 15-minute long identifiers that get updated? Also, not sure you can limit to surroundings just yet... people are still moving too much.
