 An Architecture for a Public Identity Infrastructure Based on DNS and
                             OpenID Connect


   The following document describes an architecture for an open, global,
   federated Public Identity Infrastructure (PIDI), based on the Domain
   Name System (DNS) and on the OpenID Connect framework built over the
   OAuth protocol.

1.  Introduction

   How to deal with online identities is one of the great unsolved
   problems of today's Internet: each Internet user has to authenticate
   for hundreds of different online services, all of which require some
   personal information that he or she has to provide and maintain
   separately; and this leads to severe usability and security issues.

   This document describes an architecture for a Public Identity
   Infrastructure (PIDI), an identity management framework, building on
   existing protocols and on new extensions, that can provide the three
   basic functions of online identity management - authentication,
   authorization, and management of personal information - and do so in
   an open, global and federated manner, creating a single interoperable
   personal identity space that can be shared by the entire Internet,
   while at the same time preventing any centralized control of all
   online identities and empowering users rather than identity

2.  Requirements Notation and Conventions

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   document are to be interpreted as described in [RFC2119].

   Throughout this document, values are quoted to indicate that they are
   to be taken literally.  When using these values in protocol messages,
   the quotes MUST NOT be used as part of the value.

3.  Key features

   In the PIDI architecture described in this document, people and other
   entities identify themselves in their online activities by using a
   DNS-style label, located inside an existing and valid domain name, as
   an identifier.  Such identifier allows users to log into any Internet
   service using a single account associated to their identifier.

   Identifiers are jointly managed by two complementary entities, acting
   together as the identity provider; users are able to choose the
   managers of their identifier among any number of compatible
   providers, or to host one themselves.

   Users can employ their identifier to log into any website or online
   service supporting this architecture, even without prior
   registration; on first access to that specific service, the service

   If the user consents to this access, the requested information will
