摘要
随着信息安全研究的深入,数字水印算法已成为一个研究热点。本文提出了一种基于空间域的数字水印算法。该算法利用了人眼视觉系统和BMP图像的特性,将任意类型的水印图像信息分散嵌入于宿主图像每一个字节的最低位,尽可能低地影响宿主图像,达到最佳的隐藏效果。在水印检测的过程中不需要原始图像,通过嵌入到图像中的信息位,提取水印图像。
With the deepening of the research on information security,digital watermaking has become a hotspot.This paper puts forward a method based on space domain watermaking alagorithm is proposed.This algorithm using the human visual and BMP image characteristics,and random type watermark image information will be embedded in the host image at the lowest position of each byte,affecting the host image as far as possible to attcin the best concealing effects.In the watermark detection process does not require the original image.It thorough the embed the image of bits of information to extract watermark image.
