Adding an invisible image watermark in C#?

Question

I want to insert multiple invisible watermarks into my JPEG pictures through C# code. That means that I need a .NET library that does this work and not some external batch application.

Any suggestions?

Storing "invisible" data in pictures is known as "steganography". A Google-search for "steganography .net" yields this article as its top hit - might prove useful.

Answer 2

there is a port of image magick library to c# , and it can easily perform that operation for you...
