 Different Websites / Identities
• As we come across different websites and
  different online services, pieces of our
  identity are distributed to all the companies
  and corporations that we have interacted
  with.
  Examples :   Apply an ID to log on to your SFU Account
               Apply an ID to log on to your CIBC Bank Account
               Apply an ID to log on to your VPL Account
               Apply an ID to log on to your AOL Account
                                           and ect.……………………

What’s Liberty Alliance
• Consumers and businesses can conduct
  multiple online transactions through one
  account while securing their privacy and
  personal information on any Liberty
  Alliance websites by using a great feature
  under Liberty Alliance – ( Single Sign-On ).
       Single Sign-On
• Single Sign-On allows a user to sign-on
  once at a Liberty enabled site and to be
  seamlessly signed-on when navigating to
  another Liberty-enabled site without the
  need to authenticate again.
• Single sign-on is supported both with a
  circle of trust and across circles of trust.

                                                           •

Single Logout provides synchronized
session logout functionality across all
sessions that were authenticated by a
particular identify provider.
