| 摘 要： | 1 引言近年来,随着数字技术的发展,传统的媒体技术已从模拟化向数字化转变。但数字媒体的易于拷贝和拷贝的保真特性,使版权保护更加困难,从而使数字媒体中隐藏版权信息的研究,成为信息隐藏技术中的数字隐秘术最成功的应用领域。此类技术主要包括两种:水印(Watermark)和指纹(Fingerprint)。它们的区别在于用途不同:水印技术是在数字媒体中嵌入人感官上难以察觉的版权信息,这些信息在数字

| Abstract: | Information Hiding Technology has a long history. With the development of Digital Technology, it has become a newly evolved discipline and a hot research area. Since the first Information Hiding Workshop held in 1996,the technology has been widely applied to areas such as multimedia .signal processing and protection of software Intellectual Property,but the research work in secure communication is relatively fewer. Based on success of developing a steganography tool for communication, this article summarizes the current progress in the research of Information Hiding Technology systematically, and analyzes possible countermeasures against various Information Hiding techniques. |
