Re: Digital Watermarking

I was told that stenography (Shortened from Steganography) uses a different method of invisibly embedding ownership and copyright information into a bit stream, and even printed images, that is extremely resilient.

Yep, that’;s what your printer (probably) does.

Can they be used effectively without compromising the quality of the media stream ?

In my opinion, yes. Video and audio solutions express a small amount of data over a long period of time, so the effect can be robust and unperceivable.
