Abstract

Due to the development of hologram display technology, various studies are being conducted to provide realistic contents for augmented reality. In the case of the HMD for hologram, since augmented reality objects must be rendered by a small processor, it is necessary to use a low-capacity content. To solve this problem, there is a need for a technique of rendering resources by providing resources through a network. In the case of the existing augmented reality system, there is no problem of contents modulation because the resources are loaded and rendered in the internal storage space. However, when providing resources through the network, security problems such as content tampering and malicious code insertion should be considered. Therefore, in this paper, we propose a network rendering technique applying security techniques to provide augmented reality contents in a holographic HMD device.

홀로그램 디스플레이 기술의 발전으로 인하여 증강현실에 대한 실감형 콘텐츠를 제공하기 위한 다양한 연구들이 진행되고 있다. 홀로그램용 HMD의 경우 소형의 프로세서에서 증강현실의 객체를 랜더링하여 제공하여야 하기 때문에 저용량의 콘텐츠를 사용해야하는 문제점이 있어 이를 해결하고자 네트워크를 통해 콘텐츠의 리소스를 제공하여 랜더링하는 기술이 필요하다. 기존의 증강현실 시스템의 경우 내부 저장 공간에서 리소스를 불러와 랜더링하기 때문에 콘텐츠 변조의 문제점이 없으나 네트워크를 통해 리소스를 제공할 경우 콘텐츠의 변조, 악의적인 코드 삽입 등 보안의 문제점을 고려해야 한다. 따라서 본 논문에서는 홀로그램 HMD 디바이스에서 증강현실 콘텐츠를 제공함에 있어 보안 기법을 적용한 네트워크 랜더링 기법을 제안한다.
