[WM]: Random walk

[Faiza Younas <fa1zaunus@yahoo.com>]

Hi all,
   
  I am new in digital watermarking field.. Can someone explain how a random walk over the image (the image to be watermarked) helps
in distortion free watermarking?(.means invisible watermark)..
   
  i know its a basic question and most of you must be wondering at the question.. But the fact is, I simply want to know the answer.
   
  Thanks for your explanation in advance!
   
  Regards
   
  Faiza
