ABSTRACT: This paper presents an invisible watermark algorithm including embedding and detec-
tion for color image based on .NET GDI+. By visiting the web site (http://dgdz.ccee.cqu.edu.cn/
watermark/invisiblewatermarkb.aspx) and uploading the original image and watermark image, the color image
with the invisible watermark can be gained. By converting color image from RGB to YUV, the algorithm, based
on DCT domain, is carried out by
