基于信息隐藏技术的数字水印系统模型设计

摘要

At present the digital watermarking technology is widely used,but the index calculation and the evaluation mechanism are not perfect.This paper establish a digital watermarking system model with basic function for the practical application.Based on information hiding technology,comprehensive digital watermarking algorithms are used in this model,combined with relevant technical means, which could be completed a relatively complete digital watermark generation,embedding,detection and extraction functions.Finally,a simple example is used to verify the good performance of this digital watermarking system in multimedia copyright protection and application.%针对数字水印技术应用广泛但指标计算及评价机制普遍不够完善的现状，本文在研究常用算法的基础上建立了一个能够满足实际应用的数字水印系统基本功能模型，完成了对数字水印的指标计算及评价机制。该模型基于信息隐藏技术，综合运用了多种数字水印算法，结合相关的技术手段，完成了相对较为完善的数字水印生成、嵌入、检测和提取功能。最后通过一个简单的实例应用验证了本数字水印系统在多媒体版权保护及应用上的良好特性。
