My understanding is that Apple will store fingerprint information as a list of characteristics, scrambled with a one-way hash function. This way, even if the stored data is accessed, you'll have a hard time reconstructing the original fingerprint characteristics, and it'll be pretty much impossible to regenerate the fingerprint itself.
