With the advent of technology, it is hard to find such field where technology has not appeared. One of the most citable area where technology is applied is security. Door access system is one of the major concern of home security. It has been enhanced with the days using different techniques such as, mobile application, real-time authentication system (e.g. audio and video processing), Bluetooth and other technological inventions. Later, Internet of Things (IoT) has been introduced to this field as well. This paper illustrates, an IoT and Wi-Fi based door access control system, where a user can control the access to the door using his phone remotely within the coverage area provided by the wireless Access-Point that is situated inside the home. This system takes advantage of Biometric feature of the Android phone which is used to validate authorized user and a cloud based server as the medium of user verification. The strong point of our system is multiple layered automated security system where authentication is performed on both ends (mobile application and door access controller) beyond user's perception which prohibits unauthorized access or manipulation. We have used Raspberry Pi as the door access controller and other state-of-the art devices to create testbed of the system and verified its use in practical environment. |
