    if your viewer proviedes the possibilty to access the source code this helps viewing. but it is not necessary to copy svg-files... you just need the right URL!

      Wondering if anyone from Adobe who might be watching this list can comment?  
      It is possible to digimarc register raster images.  Are there any plans to
      build a digimarc facility into SVG data in the future?

      Hi Steven,

      My $0.02 is that it isn't possible to effectively do anything like "digimarc"
      SVG data.

      At the present time with the Adobe SVG Viewer and the Batik viewer it is
      possible to access the SVG source code.

      For the "digimarc" to be present in the raster image which the viewer renders
      the "digimarc" would also have to be present as part of the well-formed XML
      (i.e. SVG in this case) source code.

      To remove the "digimarc", assuming access to the source code, would simply be
      a matter of deleting the appropriate <digimarc> (or whatever) element in the
      source code and any comments which might also hold original copyright
      information.

      I am not defending that (possible) practice, simply pointing out that as far
      as I can see there is no practical, foolproof way of absolutely protecting
      SVG images from copying.

      Thus we have the real, practical issues thrown up such as the question which
      Penny raised.
