基于DWT的抗RST攻击鲁棒性数字水印
Robust Digital Watermark Resistant to RST Attacks Based on DWT
摘要
Abstract
Aiming at the problem that existed digital image watermark method lacks of enough robust to geometrical transform attacks, this paper proposes a novel digital watermark method based on Digital Wavelet Transform(DWT). The DWT is utilized to transform the image, and the digital watermark is embedded into the low frequency subband. The watermark detection is implemented by determine images' invariant moments. Since these moments are invariant to rotation, ,scaling and translation transforms, this method is robust to geometrical transform attacks. Simulation experimental results show this method is robust to adding noise, filtering, JPEG compression attacks and RST transforms.关键词
