A new patent application published by the USPTO (via MacRumors) shows some more detail around Apple’s use of Touch ID and the fingerprint sensor in the iPhone 5s. Apple has been mostly quiet about the specifics of how the tech works, while generally asserting that the fingerprint information never goes to a server, and only remains on the phone itself in a “secure enclave” which isn’t accessible by the rest of the system or third-party devs.
