Is there any function for getting a fingerprint image from iPhone

I'm making a program that has a feature to sign in using ONLY! A user fingerprint image from iPhone and matches it among various fingerprint images in the database, so if there is any possible way to get fingerprint image from the user in iPhone?

(basically, I want to make iPhone works as a fingerprint scanner).

Many thanks.

    I doubt there is a way due to privacy concerns, not even developers are supposed to have access to it, and even if you could it should be hashed, in addition the API only tells if the fingerprint matches or not, not more than that.

    No, absolutely not possible. It's against the Apple policy and I would say even their core values. And it is understandable as it would potentially be a very dangerous capability.

    From the Apple documentation on TouchID:

    To maximize security, your app never gains access to any of the underlying authentication data.

    But you can use the provided authentification API (e.g., to safeguard a given sensible operation).
