I want to read the fingerprint data(multiple fingerprints) using the fingerprint scanner on my phone and store this data uniquely on the cloud. Then using this stored data I want to create a Login Activity type of thing which uses the fingerprint authentication and automatically opens the appropriate activity/webpage for the concerned user.
You can't get the raw fingerprint data from the mobile's fingerprint reader. It is only to be used for authentication. You should use other methods like integrating external fingerprint readers
