   I‘ve been wondering whether the contact tracking features introduced for Covid 19 could be used to verify that pictures of an event where taken by people who were actually around the scene. That way you‘d have some reassurance that a given picture was actually from the event. Combined with pictures from different angles from different people and some kind of verified photography should make alterations harder.

      Too much potential for revealing the identities of others there.

         The functionality included time-based rotation of the identifier that supposedly at least notably increased the effort to identify/track people over a longer time frame. I never dug into the details, but I figure that works better with short-term contacts and may break if you are in contact with many people over a longer time frame. Also, like contact tracking, it should be opt-in, so that you explicitly could act as ‚eyewitness‘.
