Apple said they are talking to fingerprint scanner and the a7 directly.
If ios7 jailbroken or grant root access, will it be possible for apps to access or peek at fingerprint data.
My understanding is that Apple will store fingerprint information as a list of characteristics, scrambled with a one-way hash function.<p>This way, even if the stored data is accessed, you'll have a hard time reconstructing the original fingerprint <i>characteristics</i>, and it'll be pretty much impossible to regenerate the fingerprint itself.
Well, I'm far from being an expert but as soon as the phone grants a root access I think there is a possibility to get it.<p>Since it's stored on the phone, the print or the print informations are somewhere in your device. Encrypted or not I'm pretty sure someone is going to find out how to retrieve what he wants.
