基于置乱变换的DCT域数字水印改进算法
A DCT domain watermarking algorithm based on scrambling transforming
摘要
Abstract
We propose a DCT domain watermarking algorithm, which is consistent with Kerckhoff principle. This algorithm transforms the watermark image before the watermark embedding and embeds watermark images by key vector, which improves the robustness and security greatly. The experiments indicate that the program has a better robustness on Gaussian low-pass filtering, white noise, JPEG compression, image shearing, and other kinds of attack and a better security.关键词
