是否可以获取 TouchID 信息并与指纹数据库进行比较？
Is it possible to get TouchID information and compare to a fingerprint database?
我知道使用 LocalAuthentication，可以轻松地将 TouchID 嵌入到 iOS 应用程序中。
但是有没有可能得到TouchID信息并与其他指纹数据库进行比较？

Touch ID doesn't store any images of your fingerprint. It stores only
a mathematical representation of your fingerprint. It isn't possible
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 developed to protect passcode and fingerprint data.
Fingerprint data is encrypted and protected with a key available only
to the Secure Enclave. Fingerprint data is used only by the Secure
Enclave to verify that your fingerprint matches the enrolled
fingerprint data. The Secure Enclave is walled off from the rest of
the chip and the rest of iOS. Therefore, iOS and other apps never
access your fingerprint data, it's never stored on Apple servers, and
it's never backed up to iCloud or anywhere else. Only Touch ID uses
it, and it can't be used to match against other fingerprint databases.
