"How would a Galileo-based road pricing scheme fit into the code of practice requirement of a direct relationship with the user?" Good fucking question. We've got David Smith, the deputy information commissioner, and among others Richard Clayton of the Cambridge Computer Lab's security engineering group - that's right, the guy from Light Blue Touchpaper - to argue the point.
Clayton: "We mistake data protection for privacy and vice versa. We mistake statistical data mining for precise knowledge of events. Most of all, the politicians and the systems builders must realise that when it matters, people cheat."
Now, Bowden asks a question from the floor regarding user notification on behalf of Ben "Badscience" Goldacre, thus soaring in my estimation.
