从带水印的图像生成密码
问题描述：
我正在使用c＃进行隐形数字图像水印的项目。在该项目中，我想完成一项任务：在将水印图像嵌入到封面图像中之后，必须生成密码（类似于水印图像信息嵌入到封面图像中的特定像素中）以帮助提取过程。我是水印的新手。请给出有价值的建议来实现这个目标吗？

你想要的可能是隐写术：https://en.wikipedia.org/wiki/Steganography [ ^ ]。
要获得一些特别的帮助，你需要指出什么您想要使用的UI类型。对于System.Drawing，解决方案将与WPF或其他内容不同。无论如何，你会在CodeProject上找到很多信息，所以从一些搜索开始： http://www.codeproject.com/search.aspx?q=steganography+%28.NET+OR+C% 23 + OR + VB.NET％29& doctypeid = 1％3b2％3b3％3b13％3b14％3b5 [ ^ ]。-SA
Probably what you want is steganography: https://en.wikipedia.org/wiki/Steganography[^].
To get some particular help, you would need to indicate what kind of UI you want to use. ForSystem.Drawingthe solution would be different from WPF, or something else. Anyway, you will find a lot of information on CodeProject, so start with some search: http://www.codeproject.com/search.aspx?q=steganography+%28.NET+OR+C%23+OR+VB.NET%29&doctypeid=1%3b2%3b3%3b13%3b14%3b5[^].—SA
