Dear watermarkers,

I have a doubt regarding the capacity to embed the watermark.
=A0
There is a general belief that applying the watermark beyond the =
embedding capacity degrades the quality of the marked image. Now if
the watermark is applied far within the limits of the capacity, a room =
is left for the attackers to apply his/her own watermark on
the image and claim his ownership.
The point I would like to bring to the discussion is=A0watermarking =
using SVD(sing value decomp) leaves a lot of=A0 room for the
attackers to apply their watermark since applying watermark using svd =
underutilizes the embedding capacity.
So far I did'nt find any papers claiming the attacks on svd watermarking =
algos.
=A0
I would like to know if there has been any attacks on the svd =
watermarking algos in the recent past, If so may i have the reference
or site providing the information.
=A0
with regards
milind.
