Abstract

The fingerprint door locker is a biometric security system designed to enhance access control by using fingerprint recognition. The system replaces traditional keys with a fingerprint sensor to grant access only to authorized users, reducing the risks of unauthorized entry. It offers a secure, convenient, and efficient alternative to conventional locks, suitable for various applications like homes, offices, and institutions. The project we have worked on is a fingerprint-operated door lock system. The motive behind this project is to create a prototype of a technology-based door lock system that in the future can be a successful market-available product at an affordable price. This project is operated using ARDUINO UNO and an application, LOCKER 24 through which Bluetooth connection with ARDUINO UNO is made and further fingerprint is scanned for lock operation. The lock used for the project requires a 12V supply. The supply can be given using a DC source 12V battery or using an adapter. The C program for ARDUINO UNO is given using Aurdino IDE. Once the program is saved in ESP32, the solenoid lock can be operated and controlled using the LOCKER 24 app.

1. Introduction

In today’s fast-paced and interconnected world, security has become a primary concern for individuals, both at home and in professional spaces. Traditional security measures such as passwords, keycards, and manual locks often fall short due to their inherent vulnerabilities. Passwords can be hacked, keycards can be lost, and manual keys can be misplaced or stolen, creating a constant sense of insecurity and inconvenience. Additionally, delays caused by unavailable caretakers or forgotten keys further highlight the need for a more reliable and efficient solution.

The rise of networked systems and the increasing risk of information theft amplify the urgency to adopt advanced personal identification methods. Among the many options available, biometric systems, particularly fingerprint recognition, stand out for their unmatched reliability. Unlike passwords or cards, fingerprints are unique to each individual and cannot be replicated, making them an ideal solution for preventing unauthorized access.

A fingerprint door lock system addresses these challenges by offering a secure, user-friendly, and technologically advanced alternative. It eliminates the need for remembering passwords or carrying physical keys, ensuring seamless access for authorized individuals. With fingerprints being unique and immutable, this system significantly reduces the risk of breaches, providing peace of mind to users. The growing integration of fingerprint recognition in everyday devices such as smartphones and laptops further emphasizes its practicality and trustworthiness as a modern security measure.

 

2. Problem Identification

The problem with traditional locking systems lies in their vulnerability and inconvenience, such as the risk of lost keys, forgotten passwords, or stolen keycards, which can lead to unauthorized access and security breaches. Manual locks can be easily tampered with, and reliance on caretakers for key management often causes delays. Even smart card systems are not foolproof, as cards can be lost or misused. These challenges highlight the need for a more secure and efficient solution, such as a fingerprint door lock system, which eliminates the dependence on physical keys or passwords and ensures reliable access control through unique and immutable biometric identification.

 

3. System Overview

The fingerprint door lock system is a secure and efficient access control solution that uses biometric technology to enhance security. It consists of a fingerprint sensor, an Arduino Uno microcontroller, and a locking mechanism controlled by a relay. When a user places their finger on the sensor, the system captures and compares the fingerprint data with pre-stored authorized fingerprints. If a match is found, the Arduino triggers the relay to unlock the door; otherwise, access is denied. This system eliminates the need for keys or passwords, offering a reliable, user-friendly, and tamper-resistant solution for modern security needs.

1) The Arduino Uno: Arduino Uno is the core microcontroller in the fingerprint door lock system, processing inputs from the fingerprint sensor and controlling the lock. It compares captured fingerprints with stored data, unlocking the door via a relay if a match is found. If the fingerprint is unrecognized, access is denied, ensuring secure and efficient access control.

2) Solenoid Lock: A 12V solenoid lock operates as an electromagnet, using a coil to pull a metal slug into the centre when energized. This lock is ideal for cabinets, safes, or doors, remaining locked without power. When 9-12V DC is applied, the slug retracts, allowing the door to open. It features a slanted slug, and adjustable orientation, and requires a relay module and a reliable power supply for use with an Arduino, as it draws about 500mA of current. Avoid using a 9V battery to power it.

 

3) 9 Volt Adapter: The 9V DC 2A power adapter is a high-quality, reliable power supply suitable for various applications like CCTV cameras and wireless networks. It features over-voltage, over-current, and short-circuit protection, with high efficiency and low energy consumption. Designed for Indian sockets, it includes a 2.1x5.5mm jack, LED indicator, and stabilized output with minimal ripple. Compact and lightweight, it ensures consistent performance with input voltage ranging from 100-240V AC.

 

4) Relay: A relay is an electrically operated switch and like any other switch, it can be turned on or off, letting the current go through or not. It can be controlled with low voltages, like the 3.3V provided by the ESP32 GPIOs and allows us to control high voltages like 12V, 24V or mains voltage.There are different relay modules with a different number of channels. You can find relay modules with one, two, four, eight and even sixteen channels. The number of channels determines the number of outputs we'll be able to control.

5) Machinery used for making of project: 1) Wood cutting machine. 2) Laser cutting machine.3) Soldering machine. 4) PCB milling. 

1)       Working:

 Process of Work: The purpose of this experiment is to implement a door-locking mechanism that opens or closes the lock on the door automatically with a key code. There are two work processes for this experiment which are:

Case 1: The lock will open:

In this system, the user will enter their fingerprint in the LOCKER 24 app which is connected via Bluetooth to the ARDUINO UNO latch through the microcontroller. After scanning the print, the system runs its database and looks for a match. If any match is found, the latch opens and thus the door gets unlocked. The same thing happens when the user wants to lock the door. A correct fingerprint makes the latch close, locking the door behind the user.

Case 2: The lock will not open:

If the fingerprint is wrong, the lock will not open allowing the door to remain locked and the user has to retry until the door is opened. Scanning the wrong fingerprint will automatically instruct the user to start again from the beginning.

6. Future Scope

 The future scope of fingerprint door lock systems is vast, with potential applications in residential, commercial, and industrial settings to enhance security and convenience. Advancements in biometric technology could enable faster recognition, multi-user authentication, and integration with IoT devices for smart home automation. These systems can be combined with mobile apps for remote monitoring and control, adding features like access logs and real-time alerts. Furthermore, developments in AI and machine learning could enhance fingerprint accuracy and detect attempts at unauthorized access, making these systems even more secure and reliable. As security needs evolve, fingerprint door locks are poised to become a standard feature in modern infrastructure.

7. Conclusion

In conclusion, the fingerprint door lock system is a modern, secure, and user-friendly solution that addresses the limitations of traditional locking mechanisms. By leveraging biometric technology, it ensures that only authorized individuals gain access, eliminating the need for keys or passwords. Its reliability, efficiency, and integration potential with smart technologies make it an ideal choice for enhancing security in homes, offices, and other facilities. As the demand for advanced and tamper-proof security systems grows, the fingerprint door lock system stands out as a practical and innovative approach to safeguarding personal and professional spaces.
