Video Digital Doorlock System for Recognition and Transmission of Approaching Objects

Abstract

Current digital door lock systems are mainly designed for users' convenience, so they have weakness in security. Thus, this paper suggests a video digital doorlock system grouped with a relay device, a server, and a digital doorlock with a camera, sensors, and communication modules, which is detecting or recognizing objects approaching to the front of the door lock system and sending images and door-opening information to users' smart devices. Experiments showed that the suggested system has 96∼98% recognition rate of approaching objects and requires 17.1∼23.9 seconds for transmission on average, depending on network systems. Therefore, the system is thought to have enough capability for real time security response by monitoring the front area of the doorlock system.

Security and Usability Improvement on a Digital Door Lock System based on Internet of Things

“…Various studies [3][4][5][6][7][8][9][10][11][12][13][14][15] for enhancing the security and convenience of digital door locks have been proposed. Their summarized features are shown in Table 1.…”

“…[3] studied convenient digital door lock functions, such as remote control via the integration of mobile devices and key sharing. Lee et al [4] proposed a method for detecting an accessing object and transmitting the object image. Kwak et al [5] studied a method for opening and closing the door lock using voice recognition, without using a network.…”

“…To reduce the burden on the network, the proposed system transmits an image only when the input pass-code fails, unlike [4], which transmits a video of all accessing objects. In addition, it provides basic functions, such as remote control access and viewing all incoming and outgoing information that has been recorded on the system.…”
