This issue consists mainly of a Special Section on “Content Protection and
Forensics” with four papers edited by Sabu Emmanuel, Mohan S. Kankanhalli,
Shih-Fu Chang, Regunathan Radhakrishnan, Fulong Ma and Li Zhao. For a detailed
introduction of these four papers, please refer to the Preface written by
the organizers following this text. In addition, there is a regular paper by Xiang
and Kim entitled “Histogram-Based Image Hashing for Searching Content-
Preserving Copies.”
We hope that this issue is of interest to the research community and will
trigger new research in the field of data hiding and multimedia security.We want
to thank all the authors, reviewers, editors and, in particular, the special section
organizers, who have devoted their valuable time to the success of this sixth
issue. Special thank goes to Springer and Alfred Hofmann for their continuous
support.
Finally, it is our sad duty to report that our Associate Editor, Professor
Andreas Pfitzmann, passed away on September 23, 2010 after a short but serious
illness.
Andreas’ groundbreaking research laid the foundations for the concepts of
“Privacy by Technology” and “Multilateral Security”: in his opinion, privacy
cannot be achieved by law, but must be supported, controlled and finally enforced
by technology. Then revolutionary and utopian, these thoughts are now
commonly referred to in computer science as “privacy-enhancing technologies”.
Andreas Pfitzmann was a visionary and a pioneer. His contributions to science
and his insistence on articulating even inconvenient truths changed the way we
conceive privacy. We will miss him sorely. |
