Re: Too much egg?
Yeah, I thought the same at first but I think in suggesting a hash, you're assuming that the biometric will generate the same one each tiime --- and this is the problem --- our physical characteristics change enough over time that if you record too much information (and generate a hash based on it), then the hash is different each time your biometric is scanned, but if you take less information, then different individual's biometrics generate the same hash and you get collisions... and this is yet another reason why the whole thing can't work.
