It's almost impossible to use hashes for fingerprints with COTS scanners. You use templates which in most cases, if left in the open, can be used to reverse engineer and get a fingerprint to match that template. Though it does not have to be the original one.

I was under the impression that with a template all you can do is use that template to authenticate on that system or other system that use the same schema.

Could you elaborate? How you would go about it? Any links I can read up on?

No, really, any source on that?
