基于LSB算法的数字水印实现方法,可自由潜入和提取水印文件-LSB algorithm based on digital watermarking method, and be free from sneaking into the watermark paper

LSB算法简单，实现容易，同时可以保证数字水印的不可见性，由于可以在最低位的每个像素上都插人数字水印信息，因此有较大的信息嵌入量-The LSB algorithm is simple, easy to implement, and can ensure the watermarking invisibility, because can insert watermarking information of each pixel in the low, therefore a high embe
