“HailStorm,” is a set of user-centric XML Web services that enable developers to build solutions that work seamlessly with one another over the Internet to deliver a more personalized and consistent user experience.
Passport itself is simply an authentication service. It isn't doing anything to indicate back to the Web site what information this particular user might be authorized to access; that is something that the Web site itself would be responsible for setting up. When HailStorm becomes available, it will also use Passport as the authentication service, and then HailStorm will implement its own authorization schema on top of this in order to provide the user with security over their data.
The Liberty Alliance Project was an organization formed in September 2001 to establish standards, guidelines and best practices for identity management in computer systems. It grew to more than 150 organizations, including technology vendors, consumer-facing companies, educational organizations and governments. It released frameworks for federation, identity assurance, an Identity Governance Framework, and Identity Web Services.
The group was originally conceived and named by Jeff Veis, at Sun Microsystems based in Menlo Park, California. The initiative's goal, which was personally promoted by Scott McNealy of Sun, was to unify technology, commercial and government organizations to create a standard for federated, identity-based Internet applications as an alternative to technology appearing in the marketplace controlled by a single entity such as Microsoft's Passport. Another Microsoft initiative, HailStorm, was renamed My Services but quietly shelved by April 2002. Sun positioned the group as independent, and Eric C. Dean of United Airlines became its president
