Normally I'd agree with you about duplicates in a technological society, but they're not in a normal technological society any more - the colonies are back to, essentially, wilderness and the Galactica fleet have the small problem of not being able to trust most of their computers because of the Cylon's 1337 h4x0ring skillz. They also don't have access to the databases that they would've had prior to the war, since they're all destroyed.

So it's pretty easy to pass for someone else, as long as no one recognises you...
