Ask HN: How to map human interaction networks via BT-smartphones

Re: Coronavirus. Hi HN, a member of the mexican CDC team here (non-programmer).

Aim: to map human interactions through bluetooth, GPS and WiFi with anonymity and privacy-conscious solutions. Requirements. 1. Able to build time-space network of interactions in anonymous, non identifiable way 2. Able to send messages to the network if person becomes potential or confirmed case of COVID-19 3. Able to collect geolocalization data, surveys, without compromising user´s identifiability.

Is there anything built yet? privacykit fails to have a few of these requirements.
