This book constitutes the refereed proceedings of the 14th IFIP TC 6/TC 11 International Conference on Communications and Multimedia Security, CMS 2013, held in Magdeburg, Germany, in September 2013. The 5 revised full papers presented together with 11 short papers, 5 extended abstracts describing the posters that were discussed at the conference, and 2 keynote talks were carefully reviewed and selected from 30 submissions. The papers are organized in topical sections on biometrics; applied cryptography; digital watermarking, steganography and forensics; and social network privacy, security and authentication.

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.

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.

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. The contributions are covering the state-of-the-art theoretical and practical developments in the fields of digital watermarking, steganography and steganalysis, forensics and anti-forensics, visual cryptography, and other multimedia-related security issues. Also included are the papers on two special sessions on biometric image tampering detection and on emerging threats of criminal use of information hiding : usage scenarios and detection approaches.

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 and systems, handwriting authentication, speaker authentication, face recognition, multibiometric authentication, and on biometrics and forensics.

Obwohl digitale Medien in den letzten Jahren gewaltiges Wachstum erfahren haben, ist die GewAhrleistung der AuthentizitAt der Daten, um die IdentitAt des Besitzers oder Senders zu garantieren, Urheberrechte durchzusetzen, den Nachweis der Unversehrtheit und IntegritAt zu erbringen oder Manipulationen zu erkennen weitgehend ungelAst. Digitale Wasserzeichenverfahren bieten hier LAsungen. Sie erlauben den Nachweis von AuthentizitAt oder IntegritAt, indem Informationen direkt in das Datenmaterial eingefA1/4gt werden. Die eingebrachte Information ist nicht wahrnehmbar und so mit den Daten verwoben, daA einfaches Entfernen unmAglich ist, ohne das Datenmaterial zu beschAdigen. Ziel des Buches ist es, digitale Wasserzeichenverfahren fA1/4r Multimediadaten vorzustellen, zu beschreiben und zu bewerten. Die beigefA1/4gte CD-ROM ermAglicht es, Markierungstechniken beispielhaft auszuprobieren, das Testmaterial veranschaulicht die Ergebnisse.
