Answer 1

You can't authenticate fingerprint on the server, fingerprints are stored or authenticated using Live Scan/Biometric template. Authentication is done by comparing the current scan template with previously stored templates

First of all you don't have access to these stored templates(Not provided by the OS providers/Phone Manufacturers) and If we assume that you have access to those templates, then an efficient algorithm (Image based /Pattern based ) is required to compare the current template with previously stored templates. You can't simply authenticate it by string comparison.
