(The Swedish Post is currently spending a lot of money advertising their new Web services. For full access to such sensitive data as detailed wheather maps you have to enter your name, address and Person Number - for credit information, they say - and they will send you, by snail mail, a username and password; http://www.torget.se)
Actually, they say they'll send it by Registered Mail - so there is an "authenticated" binding between userID and person. (MIT did this for accounts on MIT-AI about 20 years ago.) They will also send a copy of your Swedish credit report. Since the Swedish Post is planning to get into offering services for a fee, their requirement for a means of payment seems reasonable, though I would have thought that a Visa number would be sufficient. They refused my application without sending a copy of my credit report (and without explanation), even though I provided them with my valid Swedish personal number. I may complain in person next week when I'm in Stockholm for vacation, though it seems like a dumb way to spend a vacation. Martin.
