Innovative IoT Smart Lock System: Enhancing Security with Fingerprint and RFID Technology

Abstract

Security concerns in residential and working environments are more critical than ever, yet traditional door locks that rely on physical keys still hold significant vulnerabilities. Those key risks include loss, misplacement, or copying and may result in unauthorized access. Moving into Industry 4.0, there is great potential to integrate IoT technology to create a far more sophisticated and resilient door access system to handle such concerns. This paper analyze the design and development of a new IoT-based smart lock system enhancing security with fingerprint recognition, RFID technology, and application control via Wi-Fi as an additional to conventional lock such as kill switch and also front desk switch. In the discussed system, the ESP8266 microcontroller is used for wireless communication. Then, Virtuino IoT applications provided the function for real-time monitoring, while HiveMQ MQTT broker secured data transmissions. Therefore, the electromagnetic locking mechanism at the door was improved by using multi-layer access control. As mentioned, the methodology would provide an integration of critical hardware parts, such as NodeMCU ESP8266, Arduino Uno and electromagnetic locks, with robust software solutions in terms of secure communication and control. Once developed, the system architecture will be simulated and tested for its effectiveness in achieving better security and operational efficiency. The opted multi-layered security system can be beneficial to residential and working environment and is designed to overcome the limitations of conventional locks. Thus, enhancing the implementation of IoT-based security solutions in everyday life.
