How are users identified in the system? The choices range from not at all to full identification that can be correlated by anybody to the user’s real-world identity.
We found the following implementation choices:
- User is anonymous
- The App does not identify its users
- User has a single global pseudonym
- The App identifies its users by pseudonym that is the same everywhere
- User pseudonyms can be resolved by the systems operator
- While other users only see user pseudonyms, the system operator knows the real-world identity of all users
- User has a different pseudonym in each relationship
- The App identifies its users by pseudonyms that are unique to a relationship
- User is fully known
- The App identifies its users by their real-world name
