Off-topic but still.. Is there no ONE technology that could identify a human

drawback in using iris scanners and retinal scanners is that excessive

that.

btw, you can extract the ratina from someone and use that to auth against - should the need arise and the task me of suiteable importance. however, asking someone for something that they and only they might know is something that is quite hard to duplicate unless that person tells you.

Sure, a subtle poke with the right sort of instrument in the right part of the person would mostly have that other person tell you what the password is - however, its still something they might opt out of :)

unlike an eye or a dna sample or finger or anything like that, which you can take even when the person in question has opted out.

(ok, back to watching Hostel, for me )
