摘　　要：文章研究了基于LSB图像信息隐藏技术的图片无损水印。该方法所嵌的载体图片,在水印写入时以随机间隔法嵌入,其间隔距离以伪随机数来控制,伪随机数的种子作为密钥;在需要还原载体图片时,只需输入嵌入时所设置的密钥,就可以通过该方法还原成原来的载体图片。经过PSNR(Peak Signal to Noise Ratio,峰值信噪比)测试得出,该方法能很好地还原载体图片,实现图片的无损水印。The image lossless watermarking studied in this paper is based on the LSB image information hiding technology.The carrier picture embedded in this method is embedded by random interval method when the watermark is written,the interval distance is controlled by pseudo-random number,and the seed of pseudo-random number is used as the key;When the carrier picture needs to be restored,just input the key set during embedding,and then the original carrier picture can be restored by this method.The PSNR(Peak Signal to Noise Ratio)test shows that this method can well restore the carrier picture and realize the lossless watermarking of the picture.
