Method of verifying whether an on-line user is a member of an organization unrelated to a company

摘要

An on-line company unrelated to an organization which has a domain name provides a service to an on-line user when the company confirms that the on-line user is a member of the organization. The organization establishes a sub-domain of the domain name of the organization, and then sets the IP address of the sub-domain to be equal to the IP address of the on-line company. The company then verifies membership by checking a cookie placed on the computer of the on-line user by the organization.
