Build a Face Recognition Login System using Python

Introduction

In recent years, face recognition logins have become more and more popular. This technology provides a secure and easy way to confirm users’ identities. The technology in these systems has improved a lot, making them more accurate and reliable. Nowadays, many businesses and organizations are using this authentication method.

The basic concept behind a face recognition-based login system is simple: instead of requiring users to enter a password or PIN code, the system uses facial recognition technology to verify their identity. The system captures an image of the user’s face and analyzes it to determine if it matches the stored image of the user’s face. If the two images match, the system grants the user access.

So, get ready for an exciting journey! In this tutorial, we’re going to develop such a Face Recognition Login System using Python and MySQL. Pay close attention to every step—we’ve got the key ingredients for a successful project launch on your system. Stick with us until the end for the full experience!

The Project Details

This project features Tkinter library in the front end and MySQL database in the back end. It offers a user-friendly interface that’s not only easy to use but also visually appealing.

In the image above, you’ll notice the main window featuring four buttons on the right side, each serving a different purpose. The initial button, ‘Login,’ is designed for accessing the system. Upon pressing it, a voice in the background will prompt, “Please center your face before the camera and wait.” Following this, a window will open, capturing the video stream via the webcam. If the displayed face matches the stored faces and the corresponding Face ID is found in the database, another voice will announce “face detected.” Simultaneously, the video stream window will close automatically, revealing the login time on the screen.

The ‘Register‘ button, the second one, opens an admin login panel. Only an admin will have the authority to register a new employee in the system. Before doing so, the admin must log in through the panel using their own credentials.

The next two buttons have the same objective as their names. The ‘Clear‘ button is for clearing all the widgets from the left frame and the ‘Exit‘ is just what it does.

Requirements and Installations

If Python isn’t already a resident on your system, fear not! Grab the latest version from their website (https://www.python.org/). Once settled, remember to install the following libraries using the provided commands.

Note that, before installing the face_recognition library, it’s necessary to install two other libraries—namely, cmake and dlib.

pip install tk
pip install PyMySQL
pip install opencv-python
pip install cmake
pip install dlib
pip install face-recognition
pip install playsound

Create a Database and Tables

To successfully launch the project in your system, first, you must create the following database, tables and declare some default data there. Assuming the MySQL server is installed in your system and you know the basics. Now move forward step by step once more.

Create a database

Let’s create a database named “employee_management”.

create database employee_management;

Create a table

Now create a table named “employee_register” under the “employee_management” database.

create table employee_register(
f_name VARCHAR(40) NOT NULL,
l_name VARCHAR(40) NOT NULL,
uid Int NOT NULL AUTO_INCREMENT,
email VARCHAR NOT NULL,
designation VARCHAR NOT NULL,
contact BIGINT NOT NULL,
dob DATE NOT NULL,
join_date DATE NOT NULL,
gender char(15) NOT NULL,
address VARCHAR NOT NULL,
PRIMARY KEY ( uid )
);

Run this command

In the previous section, we have set the user id as Integer type with auto Increment. Here, we will set a base value for it so that the counting starts from that range.

ALTER TABLE employee_register AUTO_INCREMENT=1000;

Create the ‘admin’ table

Here, we will create a separate table named ‘admin’ under the “employee_management” database.

create table admin(
username VARCHAR NOT NULL,
password VARCHAR NOT NULL,
PRIMARY KEY ( username )
);

Insert default value into the ‘admin’ table

By default, we will set a default username and password for the admin access of the Login System. Before finalizing the settings, be sure to customize these credentials according to your preferences.

INSERT INTO admin (username,password) VALUES ('Your Username Here','Your Password Here');

Summary

In this article, our topic of discussion was a Face Recognition Login System using Python. This Login System is crafted with the Python Tkinter library and MySQL database. Instead of traditional methods like typing User ID and Password, users can effortlessly log in by presenting their faces to the camera. Notably, administrators also have access to register new employees through this Login System.

Every single step is important to launch this project successfully on your system. To better understand how this face recognition login system works I would suggest you read the entire article as well as watch the Output Video above so that you don’t miss any point.
