"Understanding Windows CardSpace: An Introduction to the Concepts and Challenges of Digital Identities"


Employees with a retirement savings plan (known as a
401(k) in the United States) need to be able to interact
with their portfolio management company. Because
these portfolio management companies often handle
thousands of companies??™ employees, there is a strong
desire to have the employer authenticate the employee
and pass those credentials to the portfolio manager.
Currently, some companies douse identity federation to
allow employees to get to their accounts without authenticating
to the portfolio manager again, but this lacks the
capability for the user to know what data is shared between
the parties and requires a great deal of effort to
initially set up. A Managed Information Card provided by
the employer could be used to gain access, and thus
employees are always in control of their identities.
 Connecting to an application a business partner provides.
In many industries, employees in a company need to
connect to vendor applications across the Internet. A
good example of this is the natural gas market. Natural
gas is piped up from wells and moved through natural
gas pipelines and stations to its ?¬?nal destination. A particular
geographic area is usually serviced by a single
pipeline company, but many gas producers have wells.
