Abstract:
1. A method for trust chaining, the method comprising: generating, by a computer, a user account handle comprising a pseudonym for a user account name for an account of a given user; sharing the user account handle between a first system entity and a second system entity to create a link between the first system entity and the second system entity, wherein creating a link between the first system entity and the second system entity enables information for the user to be subsequently shared between the first system entity and the second system entity, and wherein at least one of the first system entity and the second system entity comprises an identity provider that during operation stores identity information on behalf of a plurality of users; and requesting, by a service provider, user profile data associated with the user from one of the first system entity and the second system entity, wherein the user profile data includes user data other than the user account handle and other than the user account name.
