Ml based secured voting system

This is basically ML learning + IOT based security system for voting, in this, we have to provide security
1. voter enter and input his voter id then we check in DB this id is there or not, if yes then we take fingerprint input and match with stored voter details and if matches then we take face and using ml algorithm we match with stored face and if all three matches then,
2. authorized voter display on display and shows ward no of that user and opens the gate of that ward particularly, if not matches then display unauthorized voter and buzzer is there with exit gate opens.
we have stored all the voter's details before and in that we store face and fingerprint and then further use it.
