>Tell me if I'm wrong, but maybe by "cross checking" with another data (e.g. another device with a second different conversion algorithm) I could finally find out what was your fingerprint! Sure, but that's not the same as reverse engineering your fingerprint from the "mathematical representation". It isn't possible for your actual fingerprint image to be reverse-engineered from this mathematical representation.
