An improved network architecture employs a super authority having an identity catalog to direct login authentication tasks to appropriate authorities.

In an embodiment of the invention the identity catalog comprises a listing associating account IDs with appropriate authenticating authorities.

Why it's free to use
- Filed July 30, 2004 and granted February 11, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 30, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 30, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
