User-Centric Identity for Web Applications

Time: Tuesday, May 8 (half-day, morning, 8:30am to noon)

Location: Oak


Identity is foundational to Web applications. Almost all interesting Web applications use identity, even if that identity is merely psuedononymous through cookies. Good, wide-area identity systems have not been available in the past, but recent advances suggest that they are now ready for use. These systems have been termed "user-centric identity systems".

User-centric identity is about working relationships and services between individuals and retailers, employers, membership bodies, and organizations of any kind. Because user-centric identity is not about a centralized solution, or anybody's silo, it solves different problems than the familiar ones of providing authentication and authorization services within a single organization, or federation between different organizations.

This tutorial will provide a survey of recent advances in user-centric identity technologies and a hands-on demonstration of how these technologies can be used to enhance Web applications.

Prerequisite Knowledge:

None. Some programming experience will be useful for understanding the demonstration, but much of the tutorial would be useful even for non-programmers.
