How can 2 werewolves (or other secret/outcasts group members) with current technology find/confirm each other without meeting each other in person? Also, this process is publicly known and voluntary (eg. a government initiative to have werewolves meet each other, while the government themselves do not know who are/aren't werewolves (nor do they really care)).
In this example I use werewolves, but can be any kind of physically or behaviorally distinct "in" group (so lets assume these werewolves are just like ordinary people and want normal lives, but they have the ability to turn into werewolves).
So here are the rules...
- A wereperson can transform into a werewolf at any time and this process happens instantly and they are fully in control of themselves in this form
- Werewolves can't kill anyone (or at least we can assume they are subject to similar human laws among werewolves surrounding murder)
- Normal people will always attack a werewolf if they ever find one and may seek them out (note attack could include just plain discrimination against the wereperson and all of this may not be prohibited by the law)
- Normal people know there are werewolves among them
My initial thought was something like Bumble, but with an additional checkbox for "werewolf" (so people can't just know that someone is a wereperson just by the fact that they are using a certain app / service), but people could lie on the checkbox to get the identity of other (honest) werewolves.
Anyone have any ideas? Perhaps there is some kind of game theory model that already addresses this problem (eg. the game "The Werewolves" has a game theory strategy, but that game is much more structured / different than this problem)?
* What would be a solution if werewolves could only change in the presence of another werewolf who is also attempting to transform at the same time?
