This dissertation is mainly concerning digital image watermarking problems. In Chapter 2, a detailed survey on digital image watermarking is presented. In Chapter 3, an optimal scheme is proposed to use Human Visual System model to compute masking function. It will be used to control the strength of watermark signal for optimal embedding. In Chapter 4, we propose a novel watermarking scheme based on lattice vector quantization.

本文讨论了数字图像水印及其在多媒体安全中的应用，主要围绕下列问题进行研究和创新： 1、优化的水印嵌入模型：本文对基于直接序列扩频技术的水印算法进行了改进，根据人类视觉系统感知模型，提出了优化的水印嵌入模型，在不可感知性条件的限制下，使水印的鲁棒性达到最高。
