一种用于数字图像新颖的可逆认证水印算法，把可逆水印技术用于数字图像认证。-A reversible watermarking algorithm for digital image novel, the reversible watermarking technology for digital image authentication.

基于直方图平移和差分直方图的可逆水印 是个很好的文章，我虽然没仿真出来，但思想还是蛮新的-Histogram-based pan and reversible watermarking difference histogram is a good article, although I did not simulate it, but the idea is still pretty new
