Good Watermarking as a subset of steganography should work even if you
know the algorithm. Since it should be nearly seamless, depending on
some external key to be meaningful and robust to a number of conversion
procedures (think about fair use, low qual encoding or small sampling
deletes the watermark, doing high quality reencoding preserves it)
