"The technology is not included in any playback device. The mark is completely embedded in the signal itself."Absolutely. But unless hardware recognizes this signal and does something with it, it is useless. There are many ideas on how to use a watermark, but they all require hardware support. A recorder, for example, may recognize that it is allowed to make a certain number of copies of this music.
There are already machines that monitor radio airplay of songs. These machines do not use watermarks, they actually identify the waveforms of popular songs. Watermarks are not required for this application, although Verance claims this as an important application.
I cannot predict the future, but I think the whole idea seems to be dying. Verance wants their product in every CD player, cell phone and DVD player. They want to be the worldwide solution to copy protection. I doubt any of this will happen.
