- W2088272023 abstract "시각암호는 복잡한 암호학적 연산 없이 분산된 영상을 중첩함으로써, 인간의 시각에 의해 비밀영상을 직접 복원할 수 있는 방법이다. 최근까지 시각암호 분야는 크게 복호화 된 영상의 해상도를 향상시키기 위한 비밀 분산법, 분산된 영상의 크기가 변하지 않는 비밀 분산법 그리고 크기조절에 강인한 비밀 분산법 등에 관하여 연구되고 있다. 시각암호 그 자체는 단순히 분산된 영상만 이용하기 때문에 공격받기 쉽다. 따라서 비밀영상을 안전하게 공유할 수 있는 시각암호 구조가 필요하기 때문에 본 논문에서는 실제 사용될 수 있는 기본적인 시각암호 구조에서 커버영상을 이용해 개선된 시각암호 구조를 제안한다. 제안된 방법은 커버영상의 변조를 줄임으로써 steganalysis를 어렵게 하여 확률적으로 높은 안전성을 제공한다. 또한 잡음을 생성하지 않고, 비밀영상을 온전히 복원할 수도 있음을 보였다. Visual cryptography is a scheme that recovers secret image through human vision by overlapping distributed share images without cryptographic operations. Distribution methods are still being developed for improving quality of shared images keeping size of images invariant and enhancing robustness against resize of images. Since visual cryptography only uses shared images, this fact is exploited to attack. From this fact, a scheme safe for sharing distributed images is needed. In this paper, a new visual cryptographic scheme using cover image is proposed. This scheme reduces the chance of detection against steganalysis and increases security. In addition, this paper shows that the proposed scheme can completely decrypt secret image without creating noise." @default.
