디지털 이미지에 정보를 숨기는 새로운 방법이 제안되었습니다. 우리의 방법은 장치의 신호-휘도(감마) 특성에 따라 특정 장치에서 세심하게 조정된 색상의 혼합에 정보가 숨겨져 있다는 점에서 기존 기술과 다릅니다. 이러한 재생 특성은 일반적으로 장치마다, 심지어 모델마다 다르기 때문에 커버 이미지를 다른 장치에서 볼 때 숨겨진 정보가 나타나므로 숨김 속성은 장치에 따라 다릅니다. 이를 실현하기 위해 우리는 동일하게 보이는 두 개의 체커보드 패턴을 사용하여 표지 이미지를 변조하고 숨겨진 정보에 따라 로컬로 전환했습니다. 이 두 패턴을 다른 장치에서 동일하게 재현하는 것은 어렵습니다. 우리 방법을 적용할 수 있는 방법은 이미지를 화면에서만 볼 수 있지만 인쇄할 때 경고 메시지가 나타나는 보안 인쇄입니다.

Abstract: A new method for hiding information in digital images is proposed. Our method differs from existing techniques in that the information is hidden in a mixture of colors carefully tuned on a specific device according to the device's signal-to-luminance (gamma) characteristics. Because these reproduction characteristics differ in general from device to device and even from model to model, the hidden information appears when the cover image is viewed on a different device, and hence the hiding property is device-dependent. To realize this, we modulated a cover image using two identically-looking checkerboard patterns and switched them locally depending on the hidden information. Reproducing these two patterns equally on a different device is difficult. A possible application of our method would be secure printing where an image is allowed to be viewed only on a screen but a warning message appears when it is printed.

AB - A new method for hiding information in digital images is proposed. Our method differs from existing techniques in that the information is hidden in a mixture of colors carefully tuned on a specific device according to the device's signal-to-luminance (gamma) characteristics. Because these reproduction characteristics differ in general from device to device and even from model to model, the hidden information appears when the cover image is viewed on a different device, and hence the hiding property is device-dependent. To realize this, we modulated a cover image using two identically-looking checkerboard patterns and switched them locally depending on the hidden information.
