De-identified records are common in medical research, where applicable.
The problem is that for effective epidemiological research the
self-generated ID you propose must be applied in a lot of databases
outside of health care. The epidemiologist wants to know when you
were born, when you give birth or die or buy liquor, your income,
standard of living, grade of radon contamination in your house,
what Web-pages you access etc etc. (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)
So in the end you haven't really gained much by creating your own
ID - it will be just as useful to the State as if they had
given it to you.
