Stefan Brands on User-Centric Identity Management and Privacy

A very nice presentation (and short summary) on the dangers of the current frenzy of "user-centric" ID-management. Stefan looks at how

the data subject is in essence contributing to “super-federation”,

thereby weakening instead of improving privacy and user control. He provides a number of criteria to assess if any identity-management system actually protects privacy. It's one of the best pieces on the subject I've seen so far. Stefan should re-formulate his criteria into the "laws of privacy-friendly identity", as they are much more to the point that the Ontario ones.
