摘　　要：利用二值图象的边缘处嵌入数据,并根据所能嵌入数据的位置的行列数来决定嵌入的数据是1还是0.基于Matlab的仿真实验结果表明,载体图像与原始二值图像相比没有明显降质,嵌入的数据可以无损恢复,原始图像也可以无损恢复.该算法是脆弱的,嵌入的数据量不大,但可以作为一种数据隐藏的手段,也可以用来检测图像是否被改动过.A simple binary image data hiding algorithm is proposed in this paper. In this algorithm,we embed data at edge of binary image,and decide the value of embedded data which is 1 or 0 by the position of the image pixel. The experimental results based on Matlab show that the embedded data is invisible and moreover may be completely recovered. This algorithm is fragile and can only embed a small number of data,but it may be taken as a mean of data hiding,and can also be used to detect whether the carried image has been modified.
