Doc comments on Esther Dyson’s Release 1.0 piece on identity management (executive summary is available for free download following registration) and PingID.
What’s cool about PingID is that it’s an identity infrastructure (open source at the bottom, so it qualifies for ubiquity) that proceeds outward from the individual, rather than one that’s imposed from the outside by a company like Microsoft (with Palladium) or by an organization like the Sun-led Liberty Alliance ˜ yet is compatible with those schemes and others like them.
Also, on this subject of identity management, the Security Management weblog has a useful pointer to a chapter of Phil Greenspun’s work on the more traditional approaches to user registration and management.
