Applications of digital watermarking

Broadcast monitoring:
Watermarks are used in broadcast monitoring by inserting watermarks in the message that is to be transmitted. This is done before signal (audio or video) is broadcasted

Secret communication:
This was one of the earliest applications of watermarking technique. It is a process of transmitted secret messages in concealed form. Specially designed programs are there to accomplish these tasks.
Copy control:
Many watermarks do not actually prevent the coping of content into which they are embedded, but serve as identification marks of the genuine owner of it. But using certain mechanisms that detect the watermarks and inhibit the copying of the information, it is possible to preserve the integrity of the information.
