摘要
信息隐藏技术包括隐写术和数字水印技术。位图的最不重要位隐藏技术是当今流行的基于图像的信息隐藏技术。首先介绍了数字水印技术的基本原理,然后详细论述了基于最低有效位的数字水印技术的实现过程,通过实验给出了嵌入水印后的图像的效果,最后指出了这种技术的局限性。
Information hiding and information hiding analyse are widely used in many fields in recent years. Steganalysis is the attack on steganography which includes detecting, destroying and cracking. LSB embedding is the very common method to hide message in digital images. Information hiding technologies includes digital watermark and steganography. In the paper, we firstly give the basic principle of digital watermarking techniques. Then we describe the watermarks based on LSB .with the experiment ,we give the images which embedded the watermark. At last , we point out the limits of the techniques.
