1. Match in database

You cannot match fingerprint in database, please read this : https://en.wikipedia.org/wiki/Fingerprint_recognition

You have to match templates, thanks to a specific algorithm. To match on server, you need AFIS solution: https://en.wikipedia.org/wiki/Automated_fingerprint_identification

2. Extract fingerprint in Android or iOS

It's not possible to obtain fingerprint data (image or template) from Android or iOS except with an external fingerprint reader with specific SDK.
