Human like fingerprints for robots

Human like fingerprints for robots, if we can make it then from where we will match it against human fingerprints database.

Some questions on this:

- So where is human fingerprints database, does it exist somewhere?

- What if that database does not exist and we make a fingerprint that already exist in a existing human

- Also what happen if that newly generated fingerprint is to be used by someone (or the one who give this fingerprints in human) will add it in future i.e. if it is reserved for future use then what?
