Abstract: Digital watermarks have been proposed as a method for discouraging illicit copying and distribution of copyrighted material, and to create secure digital image libraries by adding to images copyright and userright information. Using a robust digital watermark to detect and trace copyright violations has therefore lot of interest. This paper describes an approach to embedding a digital watermark using the Fourier transform. The paper also addresses the difficult problem of oblivious watermark... (Update)

...itself may be falsely decoded. Some alternate schemes consist of using cross correlation as in [20, 22, 5] or Bayesian models as in [11]. The advantage of using the template is that it is much more robust than the watermark itself since we concentrate a significant...
