In this paper, we proposed an effective technique that greatly improves the security of the watermark by concealing the multiple-encrypted watermark in the LSB of the image pixel. Even if multiple encrypted watermark hidden in the LSBs of an image pixel are extracted, it is impossible to decrypt them, so the security of the watermark is maintained very high. If the watermark is multiple encrypted and hidden in the image using the proposed technique, the visual quality of the watermark-hidden image is very high, making it impossible to distinguish between the original image and the resulting image in which the watermark is hidden. The original watermark data can be completely extracted without loss, according to the procedure of the proposed technique, from the resulting image that the watermark is encrypted and hidden in the original image. The performance of the proposed technique was analyzed mathematically and the superiority of the proposed technique was confirmed through experiments. The proposed technique is an excellent image watermarking technique that greatly improves the security of the watermark hidden in the image compared to the existing technique.

본 논문에서는 다중으로 암호화한 워터마크를 영상 픽셀의 LSB에 은닉하여 워터마크의 보안성을 크게 향상시키는 효과적인 기법을 제안하였다. 영상 픽셀의 LSB에 은닉되어 있는 다중 암호화된 워터마크를 추출하여도 이를 해독하는 것이 불가능하기 때문에 워터마크의 보안성이 매우 높게 유지된다. 제안된 기법을 사용하여 워터마크를 다중으로 암호화하여 영상에 은닉하면, 워터마크가 은닉된 영상의 시각적 화질이 매우 높아 원본 영상과 워터마크가 은닉된 결과 영상의 구별이 불가능하다. 워터마크를 다중으로 암호화하여 원본 영상에 은닉한 결과 영상으로부터, 제안 기법의 절차를 따라 원본 워터마크 데이터를 손실 없이 온전히 추출할 수 있다. 제안된 기법의 성능을 수학적으로 분석하고 제안된 기법의 우수성을 실험을 통하여 확인하였다. 제안된 기법은 기존의 기법에 비하여 영상에 은닉된 워터마크의 보안성을 크게 향상시킨 우수한 영상 워터마킹 기법이다.
