웨이블릿 트리 기반 워터마킹 알고리즘은 저작권 보호 및 소유권 확인을 위해 웨이블릿 계수 에너지 차이를 사용합니다. WTQ(Wavelet Tree Quantization) 알고리즘은 에너지 차이를 워터마킹에 활용하는 대표적인 기술이다. WTQ의 암호 분석에 따르면 보호된 이미지에 삽입된 워터마크를 성공적으로 제거할 수 있었습니다. 본 논문에서는 웨이블릿 트리 그룹 변조 구조, 즉 WTGM(Wavelet Tree Group Modulation)을 기반으로 하는 새로운 차동 에너지 워터마킹 알고리즘을 제시합니다. 호스트 이미지의 웨이블릿 계수는 분리된 슈퍼 트리(각 슈퍼 트리에는 두 개의 하위 슈퍼 트리가 포함됨)로 나뉩니다. 서브슈퍼 트리의 에너지가 가까워지도록 그룹 전략을 사용하여 상대적으로 높은 주파수 성분에 워터마크를 삽입합니다. 웨이블릿 트리 구조, 부분 집합 합계 및 포지티브/네거티브 변조를 사용하면 WTQ 방식의 불안정한 단점을 효과적으로 개선할 수 있습니다. WTGM용 HVS(Human Visual System) 통합은 워터마크 이미지에 더 나은 시각적 효과를 제공합니다. 실험 결과는 견고성과 민감성 측면에서 우리 알고리즘의 효율성을 보여줍니다.

Abstract: Wavelet tree based watermarking algorithms are using the wavelet coefficient energy difference for copyright protection and ownership verification. WTQ (Wavelet Tree Quantization) algorithm is the representative technique using energy difference for watermarking. According to the cryptanalysis on WTQ, the watermark embedded in the protected image can be removed successfully. In this paper, we present a novel differential energy watermarking algorithm based on the wavelet tree group modulation structure, i.e. WTGM (Wavelet Tree Group Modulation). The wavelet coefficients of host image are divided into disjoint super trees (each super tree containing two sub-super trees). The watermark is embedded in the relatively high-frequency components using the group strategy such that energies of sub-super trees are close. The employment of wavelet tree structure, sum-of-subsets and positive/negative modulation effectively improve the drawbacks of the WTQ scheme for its insecurity. The integration of the HVS (Human Visual System) for WTGM provides a better visual effect of the watermarked image. The experimental results demonstrate the effectiveness of our algorithm in terms of robustness and imperceptibility.
