Consider the information can be used for more than just identifying you... if you have sufficient quality biometrics they can be used to _impersonate_ you, including "fingering" you for things you didn't do. Police forces have "planted" evidence for decades now, biometrics can be just another thing that can be planted. The problem is, you can't fight it, because it's absolutely unique to you (with some extreme exceptions).

This is one of _many_ reasons why biometrics need to be a personal civil liberty. The individual must have the right to say "no" to _any_ "requirement" for giving up biometric data, unless they are convicted as a criminal (IMO). Because once you deliver that information, you _cannot_ trust any other party _to actually do what they say will do and destroy said data_, and that's not even considering just poor storage of said data.

Once your biometrics are in a database, you're fucked *for life* because it's completely unrealistic to have it destroyed with absolute certainty. This needs to be a *global human right*, as hard as those are to come by still.
