I agree totally!!! I'm really reticent to give out any personally identifying info, whether physical or otherwise. In England you are captured on camera every seven seconds (or so I read) and I'm not convinced the right controls are in place on biometrics or any of the other surveillance systems that make their usage fair and controlled.

I have an idea though to make it harder for anyone who did want to steal my identity - redundant data. My passport has my old name on, my driving licence an old photo. I let credit cards lapse, play swopsies with supermarket loyalty cards and let false (benign) data roam freely (I'm a 92 year old who likes puppies according to my bank!*) Although of course this makes it really hard to prove you are who you say you are.
