Digital Watermark Research Based on Fingerprint Feature Data
基于指纹特征数据的水印技术研究

There are two kinds of watermark data in traditional digital watermark: one is the pseudo-random sequence(one dimension),the other is binary image(two dimension).In this paper ,we propose a new algorithm to insert 256-gray-scale fingerprint images to original images through inserting watermark information to each channel of R,G,and B of the original image ,and the original image can be both gray-scale image or color image .The experiment results show this algorithm has a good robustness.
