Abstract

This paper presents a novel three-dimensional (3D) object encryption scheme by combining the use of the virtual optics and the chaotic sequence. A virtual 3D object is digitally produced using a two-dimensional (2D) elemental image array (EIA) created with a virtual pinhole array. Then, through a logistic mapping of chaotic sequence, a final encrypted video can be produced. Such method converts the value of a pixel which is the basic information of an image. Therefore, it gives an improved encryption result compared to other existing methods. Through computational experiments, we were able to verify our method's feasibility and effectiveness.

본 논문에서는 집적영상에서 가상광학과 혼돈 수열(chaos sequence)을 결합하여 3차원 물체 영상을 암호화는 새로운 방법을 제안한다. 먼저 가상 핀홀 배열(virtual pinhole array)을 통하여 2차원 요소영상 배열(EIA)을 생성한 후, 이를 이용해 3차원 물체를 디지털로 만든다. 그 후 혼돈 수열의 논리적 연산을 통해 최종 암호화 영상을 만든다. 이러한 방법은 영상 데이터를 시각화하기 위한 영상의 기본 정보인 픽셀의 값을 변환시키기 때문에 기존의 암호화 방법보다 향상된 암호화 결과를 얻을 수 있다. 실험을 통해 본 암호화 방법의 유효성과 안정성을 검증한다.
