Smart and Secure Door Lock with Dual-Factor Authentication for Critical Zones

Abstract

In recent years, the Internet of Things (IoT) technology has received a lot of attention, and almost every person wants their tasks to be done automatically and securely by using IOT devices. Due to increasing concerns about security, most traditional home locks are being replaced with IOT-based smart door lock systems. However, there is no appropriate solution to the requirements for organizations, banks, offices, and other critical locations that require more protection. As a result, smart home locks, which were primarily designed for residential use, are the only option left for organizations. As a solution, a security system is devised using Raspberry Pi based on two-type authentication involving either RFID or fingerprint identification in the first step and face recognition in the last step. Along with this, there are other functionalities, such as remote door access, a log registry to keep track of persons entering and leaving the premises, alerts for suspicious activity, and a specialized IR-based door feedback system that monitors whether the door is open or closed. The presented system aims to provide organizations with a reliable and secure means of controlling access to their premises with an average processing time of around 8 seconds.
