摘　　要：针对信息隐藏领域的隐秘技术和数字水印技术,以最低有效位、离散余弦变换等为理论基础设计了几个信息隐藏技术实验。实验主要采用Matlab工具,结合信息隐藏知识要求,从实验目的、实验内容、实验步骤和实验扩展等方面说明了信息隐藏技术的原理。与传统信息安全课程实验设计相比,实验方案设计简单明了,弥补了传统信息安全实验课程中信息隐藏实验的缺失。Information hiding is one of the important parts in modern information security. It is a very important tool for training students ＇ practical ability. In order to strengthen the students ＇ understanding of theoretical knowledge and handling ability,we design some experiments for two main points in information hiding： steganography and watermarking based on least significant bits（ LSB） and discrete cosine transform（ DCT）. According to the information hiding knowledge,these experiments include experimental purpose,content,process and extension based on Matlab toolbox.Compared with the traditional experimental design,the proposed experiments are easy to understand,and can enrich the knowledge structure of the students.
