| 摘 要： | 从数字水印算法与数字媒体交易协议相适配的视角,根据最新的数字图像交易协议的特点及其对数字图像水印算法的基本要求,对现有的一种小波域数字图像水印算法进行了多方面实质性改进研究,提出了一种新的基于提升小波变换的彩色图像交易水印算法。该算法实现了版权标识水印和消费者数字指纹的同时嵌入,因而具有版权认证和盗版追踪的双重功能。仿真实验表明,该算法比原算法在不可感知性等方面具有更好的性能。

| Abstract: | In view of that digital watermarking algorithms have to accord with the basic requests of digital media marketing protocol, this paper presents a buyer-seller watermarking scheme for color images based on lifting wavelet transformation. The algorithm embeds a seller＇s copyright watermarking and a buyer＇s digital fingerprinting in the same color image, so it can combine an appropriate buyer-seller watermarking protocol to identify who holds the legal copyright of the work and trace the illegal reseller. In our scheme we improve a wavelet domain algorithm essentially and get better performance in the aspect of imperceptibility. |
