초록

스테고(Stego) 이미지 분석 측면에서 스테고-분석(Steganalysis) 툴의 기본적인 공격 목표는 데이터 은닉에 의한 스테고-미디어의 통계적으로 비정상적인 부분을 찾음으로서 데이터 은닉의 존재를 탐지 하는 것이다. 본 논문에서는 디지털 이미지를 위해 (7, 4) 해밍코드를 개선한 방법으로 데이터 은닉 스킴을 제안하였다. 제안한 방법은 원 영상이미지에 9비트 마다 6비트의 데이터를 은닉하는 방법이다. 실험결과 제안한 방법은 0.67bpp의 데이터 은닉 성능을 보이며 기존의 방법들에 비해서 스테고 영상의 질이 평균적으로 약간 더 좋은 것으로 나타났다.

The primary goal of attack on steganographic images, termed steganalysis, is to detect the presence of hidden data by finding statistical abnormality of a stego-media caused by data embedding. This paper proposes a novel steganographic scheme based on improving the (7, 4) Hamming code for digital images. The proposed scheme embeds a segment of six secret bits into a group of nine cover pixels at a time. The experimental results show that the proposed scheme achieves a 0.67bpp embedding payload and a slightly higher visual quality of stego images compared with the previous arts.
