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

??? Who is the IP in that scenario? The natural choice is the
employer. After all, purchases within that application happen in
the context of the company-supplier partnership, and it is only
natural that the latter will restrict the service to employees only.
Hence, the employee??™s identity must be issued by the employer.
The employer, however, might not actually know what the
spending limit of the employee is. What if the value ?¬‚uctuates
following some business rules speci?¬?c to that vendor? The
agreements between the two parties may state that there??™s a
monthly buffer, and beyond a certain threshold only managers
are allowed to make expensive purchases. Sure, the employer
may incorporate those business rules in its IT system; however,
that would not scale at all because it would have to do so for
every partnership it entertains and differentiate all expenses as
they are made as opposed to keeping a single bucket sorted out
at invoicing time. It is much easier, and far more natural, to
leave that function to the supplier. The hardware vendor knows
how much the employer spent so far because it has a good business
reason for knowing it. It has yet to invoice it.
