'''Hidden Watermark''' by mchall (Mike Hall) is an open source C# program that embeds a hidden watermark in an image using a blind DWT-DCT approach. Unlike steganographic methods, this hidden watermark is resistant to various forms of attack. Limited to a black and white 32x32 watermark image.


Image can be resized, recompressed, blurred, etc and still be able to recover the watermark.
