Hi watermarkers,
  
  Regarding to image watermarking techniques in frequency domain using FFT, I found that there are lots of algorithms for embedding
on the magnitude coefficients of FFT, but just a few papers for the phase ones, although phase is more important than amplitude. I
know two papers using phase FFT: one was by Ruanaidh
1996 and the other using phase modulation by Alturki 2000.
  
  I wonder if any of you can recommend me other papers/algorithms that make use of the phase of FFT for image watermarking? I'd like
to discuss on this.
  
  Thanks in advance.
