Can the TouchID information be retrieved and compared to the fingerprint database?
From Apple doc
Touch ID does not store your fingerprint images. It only stores the mathematical representation of your fingerprint. It is impossible for someone to reverse engineer your actual fingerprint image from this mathematical representation. The chip in your device also includes an advanced security architecture called the Secure Enclave, which was designed to protect your password and fingerprint data. The fingerprint data is encrypted and protected only by the key to the Secure Enclave. Fingerprint data is only used by the Secure Enclave to ensure that your fingerprint matches the registered fingerprint data. A protective enclave walled from the rest of the chip and the rest of the iOS. Therefore iOS and other apps never access your fingerprint data,it is never stored on Apple servers, and it has never supported iCloud or anywhere else.Only the Touch ID uses and it cannot be used to match with other fingerprint databases.
