Residential access control system using QR code and the IoT

Abstract

This paper presents a residential access control system (RACs) using QR codes and the internet of things (IoT) to improve security and help house owners. The contribution of this paper is that it proposes two mechanisms in the authentication phase and the verification phase, respectively, to enhance residential access control. The main idea is using cryptography between smartphones and access control devices. The cryptography compares secret codes on the key server via the internet. The RACs can notify a user of the residential access status through the LINE application and show the statuses of devices through the network platform for the internet of everything (NETPIE) in real-time. We compare this system’s performance with that of the current access control methods in terms of security and access speed. The results show that this system has more security and has an access speed of 5.63 seconds. Moreover, this system is safer and more flexible than the comparative methods and suitable for contactless authentication.

Automatic face recording system based on quick response code using multicam

“…The use of quick response (QR) codes is now widely found, such as for attendance systems, and validation systems [1], [2]. Incorporating a QR code application with a face detection application is important to produce a system that is able to automatically save faces and read QR codes in the workplace at the same time.…”
