Full Title or Meme

A means to distribute the sources of Identifiers and Attributes while giving more choice to Users.

Context

  • Decentralized ID is a somewhat different concept in that it envisions an identity which is centralized with the user rather than with a central authority.
  • The current paradigm in open identity is for each conforming Relying Party to provide a list of Identifier or Attribute Providers that the User could chose from to allow access.
    • In this model it was up to the Relying Party to establish a link and share a secret with the Identifier or Attribute Provider in advance of any transactions.
    • It also required the user to pre-register with one or more of those providers, typically one of the big social sites, like: Google, Microsoft or Facebook.
  • The current most common protocol for some sort of a Distributed Identity was OpenID Connect which included Self-issued Identity, but that concept never succeeded in the marketplace.
  • Now other organizations believe that they can succeed where the OpenID foundation failed.

Problems

  • The big problem is Trust where there are no standards or examples of any trust without a history of trusted behavior.
  • Beware of time-stamping services posing as trust anchors. Bellcore created such a service in the early 1990 and spun it off into a separate company in 1994.[1] None of these services provide any trust in the contents of the documents.
  • Proof of Persistent Identity must be provided. This can be little more than the inclusion of a public key in a blockchain, but that cannot provide any Assurance of protection of the Credential.
