摘要
首先介绍了一种基于LSB算法的信息隐藏方案,在该方案中信息嵌入到根据密钥随机选取的图像像素的最低k位,接收方无需原始图像就可将隐藏信息提取出来;然后用MATLAB工具实现了方案,实验结果表明该方案简单,容易实现,具有失真度小、隐藏量大、准确性高、良好的不可见性和安全性等特点。
A data-hiding method based on image LSB is firstly introduced,in which data are hidden in the LSB of image pixels selected from image according to a key and retrieved without the original image, and then the method is implemented with MATLAB software, results of the experiment show that the method is simple, easily implemented, and of low distortion,large number of hidden-data, high accuracy, better imperceptibility, safety and so on.
