Abstract

A Pseudonym Server provides credentials for pseudonyms to clients, which can then use those credentials in interactions with other clients. The credentials are based on proof of right to use a pseudonym, attestations, identity verifications, and/or aggregations. Communication between clients can be over a wide variety of media.
