[WM]: Any real-world use of informed / Costa watermarking schemes ?

["Frank Hartung \(AC/EDD\)" <frank.hartung@ericsson.com>]

Dear watermarkers,

I know about the theory of informed watermarking schemes (aka Costa schemes, QIM, binning schemes etc.). I have understood it has
been theoretically shown they perform better than the old-fashioned blind schemes (spread spectrum and the like).

I have however a feeling that in practical, "real-world"  applications, blind embedding schemes like spread spectrum are still
mainly used. Or am I wrong ? What I would like to find out is where informed schemes (Costa schemes, QIM schemes etc) are used in
real deployments, i.e. who can tell me about research or even commercial applications using such schemes ? Any information
appreciated. 

Thanks, best regards, Frank
