This text presents a review of current perspectives on communications and multimedia security in 2001. It examines requirements, issues, and solutions pertinent to securing information networks according to a multi-disciplinary approach covering research aspects, legal aspects, and applications. A wide spectrum of topics is discussed, including: Web security; watermarking; cryptographic algorithms; system security; mobile security; and secure key protocols. This volume contains papers presented at the fifth Joint Working Conference on Communications and Multimedia Security (CMS'01), which was sponsored by the International Federation for Information Processing (IFIP) and held on May 21-22, 2001, in Darmstadt, Germany. It should be of interest to information security specialists, computer professionals, communication systems professionals, EDP managers and auditors, and researchers in the area.

The volume contains the papers presented at the fifth working conference on Communications and Multimedia Security (CMS 2001), held on May 21-22, 2001 at (and organized by) the GMD -German National Research Center for Information Technology GMD - Integrated Publication and Information Systems Institute IPSI, in Darmstadt, Germany. The conference is arranged jointly by the Technical Committees 11 and 6 of the International Federation of Information Processing (IFIP) The name "Communications and Multimedia Security" was first used in 1995, Reinhard Posch organized the first in this series of conferences in Graz, Austria, following up on the previously national (Austrian) "IT Sicherheit" conferences held in Klagenfurt (1993) and Vienna (1994). In 1996, the CMS took place in Essen, Germany; in 1997 the conference moved to Athens, Greece. The CMS 1999 was held in Leuven, Belgium. This conference provides a forum for presentations and discussions on issues which combine innovative research work with a highly promising application potential in the area of security for communication and multimedia security. State-of-the-art issues as well as practical experiences and new trends in the areas were topics of interest again, as it has already been the case at previous conferences. This year, the organizers wanted to focus the attention on watermarking and copyright protection for e­ commerce applications and multimedia data. We also encompass excellent work on recent advances in cryptography and their applications. In recent years, digital media data have enormously gained in importance.

This book constitutes the refereed proceedings of the 16th International Workshop on Digital Forensics and Watermarking, IWDW 2017, held in Magdeburg, Germany,in August 2017. The 30 papers presented in this volume were carefully reviewed and selected from 48 submissions.

It is our great pleasure to present the proceedings of the 9th IFIP TC-6 TC-11 Conference on Communications and Multimedia Security (CMS 2005), which washeld in Salzburg on September 19-21,2005.Continuing the tradition of p- vious CMS conferences, we sought a balanced program containing presentations on various aspects of secure communication and multimedia systems. Special emphasis was laid on papers with direct practical relevance for the construction of secure communication systems. The selection of the program was a challenging task. In total, we received 143 submissions, from which 28 were selected for presentation as full papers. In addition to these regular presentations, the CMS conference featured for the ?rst time a "work in progress track" that enabled authors to report preliminary results and ongoing work. These papers were presented in the form of a poster sessionduringtheconference;anextendedabstractofthepostersappearsinthis proceedings volume.

Their assistance in organizing CMS 2005 was greatly appreciated.

Obwohl digitale Medien in den letzten Jahren gewaltiges Wachstum erfahren haben, ist die Gewährleistung der Authentizität der Daten, um die Identität des Besitzers oder Senders zu garantieren, Urheberrechte durchzusetzen, den Nachweis der Unversehrtheit und Integrität zu erbringen oder Manipulationen zu erkennen weitgehend ungelöst. Digitale Wasserzeichenverfahren bieten hier Lösungen. Sie erlauben den Nachweis von Authentizität oder Integrität, indem Informationen direkt in das Datenmaterial eingefügt werden. Die eingebrachte Information ist nicht wahrnehmbar und so mit den Daten verwoben, daß einfaches Entfernen unmöglich ist, ohne das Datenmaterial zu beschädigen. Ziel des Buches ist es, digitale Wasserzeichenverfahren für Multimediadaten vorzustellen, zu beschreiben und zu bewerten. Die beigefügte CD-ROM ermöglicht es, Markierungstechniken beispielhaft auszuprobieren, das Testmaterial veranschaulicht die Ergebnisse.

This book constitutes the thoroughly refereed proceedings of the COST 2101 International Workshop, BIOID 2011, held in Brandenburg (Havel), Germany, in March 2011. The 25 revised full papers presented were carefully reviewed and selected from numerous submissions and are completed by an introduction on COST. The papers are organized in topical main sections on theory andsystems, handwriting authentication, speaker authentication, face recognition, multibiometric authentication, and on biometrics and forensics.
