摘要
阐述了信息隐藏技术的基本原理、信息隐藏系统的一般模型和设计要求,分析了信息隐藏技术的两个主要分支—隐写术和数字水印对性能指标的不同要求,探讨了以数字图像作为载体的隐藏算法的实现方法,以及信息隐藏技术在通信保密和版权保护等方面的应用。
The information hiding technology is a new developing information security technology in recent years This paper first introduces the fundamental conception of the information hiding technology comparing with encryption, then describes a general model of information hiding system and its performance. Furthermore, analyzes the difference between steganography and digital watermark, meantime discusses several algorithms. Finally, discusses the application in secret communications and copyright protecting.
