Touch ID doesn't store any images of your fingerprint, and instead relies only on a mathematical representation. It isn't possible for someone to reverse engineer your actual fingerprint image from this stored data.

> Your fingerprint data is encrypted, stored on device, and protected with a key available only to the Secure Enclave. Your fingerprint data is used only by the Secure Enclave to verify that your fingerprint matches the enrolled fingerprint data. It can’t be accessed by the OS on your device or by any applications running on it. It's never stored on Apple servers, it's never backed up to iCloud or anywhere else, and it can't be used to match against other fingerprint databases."

This both reaffirms my previous understanding of biometrics and reassures my apprehension with current implementations. It was my understanding that biometrics, at least fingerprinting but also Face ID currently, used a numerical, or more appropriately described, mathematical representation. The fact that the operating system can't access this information is reassuring. This, of course, still doesn't keep a malicious actor from accessing the device from coercion but if that's a security risk someone should probably be prepared for torture.
