Wireless networks, at a personal level have a lot of potential and are under rising interest, with applications like contact tracing for health protection.
This applications have a large impact on privacy, but also a large potential for establishing peer to peer networks based on proximity based on mutual trust.
For example, if I enter a supermarket, the kind of interaction triggered by presence is very different from when I enter my company, or mi kids' school. Different roles, different communication channels, different level of trust.
Every association is based on mutual trust, rights to send information and rights to request information which are allowed from the individual to the to the individual. location and from the location to the individual.
These problems are largely uninvestigated and there is no standard protocol to regulate these interactions in a secure and privacy respecting way.
