Abstract

In modern times, many IoT products are being used as all things and devices are connected to the Internet and IoT products become easily accessible through the network. For the convenience of users, IoT products can be remotely operated automatically without manual operation. Various research and development are underway to improve the convenience of users by using IoT products. However, since only the convenience of the users is pursued, in terms of security, there is a serious problem that exposes the user's personal information. This paper has proposed a method to apply $moir{\acute{e}}$ technology to IoT products in order to improve the performance of security, and a method to increase the safety of IoT products using user face authentication based on shadow $moir{\acute{e}}$ as a $moir{\acute{e}}$ phenomenon method, and the projection $moir{\acute{e}}$. When comparing the existing IoT products and IoT products applied with $moir{\acute{e}}$ technology, IoT products applied with $moir{\acute{e}}$ technology are safer in terms of security.

현대에는 모든 사물, 기기들이 인터넷으로 연결되고 네트워크를 통해 IoT 제품을 쉽게 접하면서 IoT 제품을 사용하고 있다. 사용자들의 편리성을 위하여 원격으로 IoT 제품을 직접 조작하지 않고 자동으로 조작할 수 있다. 사용자들이 IoT 제품을 이용하여 생활의 편리성을 향상하기 위한 다양한 연구개발이 진행되고 있다. 하지만 사용자의 편리성만을 추구하다 보니 보안적인 측면에서는 사용자의 개인정보 노출이 되는 심각한 문제가 발생하고 있다. 본 논문에서는 IoT 제품에 무아레 기술을 적용하는 방법을 제안하여 보안의 성능을 향상하고, 무아레 현상 방법인 그림자식 무아레, 영사식 무아레를 이용한 사용자 얼굴 인증으로 IoT 제품의 안전성을 높이는 방법을 제안한다. 기존의 IoT 제품과 무아레 기술이 적용된 IoT 제품을 비교해 보면 무아레 기술이 적용된 IoT 제품이 보안적인 측면에서 안전하다.
