An Identity Provider to Manage Reliable Digital Identities for SOA and the Web

This paper describes the implementation of the identity provider, based on open web service standards, which has been extended to distinguish between different qualities of identity attributes; therefore enabling a relying party to distinguish between verified and unverified digital identities. The contribution is the definition and representation of identity meta information for identity attributes on the identity provider side and the conveyance of this information as Identity Attribute Context Classes to a relying party.
