[edit] Watermarking vs Steganography
Watermarking is not a form of steganography. mahendra kumar dewangan
Watermarking has the objective to embed data in a document in a way, so that it:
- is hard to remove
- cannot be forged by someone else
In general it is not necessary that the watermark can not be detected. In contrary the goal of steganography is to hide data undetectable in a document.

There are many ways to make the spatial watermarking robust to cropping or translation. In fact, there are really no differences between adding something in the frequency domain over adding something in the space domain.

[edit] Wikipedia
Are images with digital watermarking generally not allowed on Wikipedia? Shawnc 02:10, 10 July 2006 (UTC)
- If you mean those visible notices, generally they're against Wikipedia style, though maybe they occur in some fair-use images where they mustn't be removed. Phr (talk) 17:11, 11 July 2006 (UTC)

According to Cox, Miller, Bloom in "Digital Watermarking" applications include broadcast monitoring, owner identification, proof of ownership, transaction tracking, content authentication, copy control and device control. The article only seems to focus on authentication. MatthewKarlsen 17:47, 18 September 2006 (UTC)
