Can anyone help me with that if can program it through Arduino or not
It is possible.
No idea what a STM32F7691 is.
How are you going to get all the voters fingerprints..
Never mind just see if the fingerprint has been detected before.
IF you mean the Arduino IDE, then This video seems to show how to begin. Check with Google from your location.
i am gonna make data file with all pre-stated fingerprint data which will be used to authenticate later
How big will that database become? Searching for a known fingerprint is the task of a computer, not a small Arduino.

i am trying to achieve it with iot
A block diagram of your proposed project would help us understand a whole lot!

I think most of the Arduino-compatible fingerprint sensors only handle a very limited number of "known" fingerprints.
Actually, you can probably make that "most electronic fingerprint sensors" - uniquely identifying one out of thousands of people by their fingerprint is a much harder problem, using (local) machines in the $20k range connected to a much more expensive database - new AFIS systems are budgeted in the $10M range.
Edit: Also Fingerprints :
Through the AFIS gateway, users receive the results of their checks very quickly:
- For individuals who are unknown in the database, this takes only a few minutes (automatic search)
- For individuals known in the database, this takes about an hour (semi-automatic search)
Just a bunch of fingerprints is not very useful. You write of authentication. Are you also looking at a data base of names AND fingerprints? Or do you need names and addresses?
