【Abstract】 Considering the character of human visual system (HVS) and the actual demand in information protection,this paper describes a method to embed a digital watermark into a digital image in the spatial domain.At the same time,it provides a number of experimental results about the scurity and robustness of the digital watermark in the watermarked image.The results indicate that it is available to embed digital watermark in spatial.This spatial domain method is visible,simple and easy to control the pixels change happened in the image.The research and experiment results in this paper have a high value both in further studying digital watermark and developing a computer software concerned.更多还原
