You are having a great deal of fun at the intersection of probability and statistics. :-)
There are great books on issues of identity, from a non-rigorous standpoint. There is a famous medical case of a man who took an iron bar through his skull. Upon removal, he was "himself", but had a different (and far more irascible) personality.
The old man is the infant, in terms of identity. Because of continuity. The weaknesses of security (as I said above, what you have, are or know) is that all of them can be disrupted. You can lose your key, lose a hand or fingerprint, or forget a rarely used password.
(People know my father-in-law for his incredible roller-blading abilities. But thanks to Parkinson's, he hasn't strapped on skates for a decade. Is he still the same identity?)
