Of course there is the case of a rogue terminal surreptitiously saving your fingerprint or photo, but even before we had automated facial recognition at border crossings, you'd still have to hand in your passport to be scanned (to read the MRZ) and stamped, so a rogue terminal could have been saving photos all along.
* That is, of course, what the law says. I have no reason to believe "the government" is breaking that law, but no way to verify either. It would probably be discovered and leaked very quickly if they were though.
Although the crackdown on illegal immigration means that I now need to prove my right to work in the UK whenever I take a new job. I'm not sure how I'd do this if I didn't have a passport.
