摘　　要：介绍了隐写术和反隐写术,说明了隐写术的原理及隐写术在文本、图像、音频中的应用。从隐写系统的绝对安全性、检测隐写消息的低效性和隐写算法的复杂多变性等方面阐明了反隐写所面临的挑战。最后指出反隐写术只能证明隐写信息的存在性而不能破译隐写信息的不足;同时简要阐明了反隐写的发展趋势。The authors introduce in this paper steganography and anti-steganography and illustrates the principle of steganographic methods and their applications in the text, images, and audio. It is illustrated that anti-steganography faces challenges from absolute safety of hidden writing system, inefficiency of detecting to complexity of steganographic algorithms. The authors point out that the anti-steganography can only prove the existence of the steganographic information, but not crack it. This paper briefly explains the trend of anti-steganography.
