> There are huge privacy implications for the first route, however

In the Netherlands, when you want to request (removal of) your data as per our privacy and person registration laws, you need to send a scan of your passport or ID card as proof of identification to the data-collecting corporation as well (which makes sense).

Fortunately you can block out and mangle large parts of this scan and they still have to accept it. It's not waterproof, but:

- you can block out or blur your photograph

- same for your social security number and the passport serial number

- place coloured letters diagonally over the scan stating that "THIS SCAN IS INTENDED TO PROVE MY REAL NAME TO GORGLE PLUS yyyy-mm-dd" (so that whoever receives it cannot use the scan for a different purpose)
