The Proceedings of the 13th International Information Hiding Conference (Prague, Czech Republic, May 2011) are available online for all to see. Much of the fine content, however, is hidden . . .
It will be revealed (in largely unreadable form) if you click the orange text reading ‘Information Hiding 13th International Conference, IH 2011, Prague, Czech Republic, May 18-20, 2011, Revised Selected Papers’ HERE (use the scrollbars to view several hundred pages of obscurantised blur) .
Note : The 14th Information Hiding Conference will be held in Berkeley, California, May 15-18, 2012.
