In multimedia and communication environments all documents must be protected against attacks. The movie Forrest Gump showed how multimedia documents can be manipulated. The required security can be achieved by a number of different security measures. This book provides an overview of the current research in Multimedia and Communication Security. A broad variety of subjects are addressed including: network security; attacks; cryptographic techniques; healthcare and telemedicine; security infrastructures; payment systems; access control; models and policies; auditing and firewalls. This volume contains the selected proceedings of the joint conference on Communications and Multimedia Security; organized by the International Federation for Information processing and supported by the Austrian Computer Society, Gesellschaft fuer Informatik e.V. and TeleTrust Deutschland e.V. The conference took place in Essen, Germany, in September 1996

This book presents a state-of-the art review of current perspectives on Communications and Multimedia Security. It contains the Proceedings of the 3rd Joint Working Conference of IFIP TC6 and TC11, arranged by the International Federation for Information Processing and held in Athens, Greece in September 1997. The book aims to cover the subject of Communications and Multimedia Systems Security, as fully as possible. It constitutes an essential reading for information technology security specialists; computer professionals; communication systems professionals; EDP managers; EDP auditors; managers, researchers and students working on the subject.

Advanced Communications and Multimedia Security presents a state-of-the-art review of current perspectives as well as the latest developments in the area of communications and multimedia security. It examines requirements, issues and solutions pertinent to securing information networks, and identifies future security-related research challenges. A wide spectrum of topics is discussed, including: -Applied cryptography; -Biometry; -Communication systems security; -Applications security; Mobile security; -Distributed systems security; -Digital watermarking and digital signatures. This volume comprises the proceedings of the sixth Joint Working Conference on Communications and Multimedia Security (CMS'02), which was sponsored by the International Federation for Information Processing (IFIP) and held in September 2002 in Portoroz, Slovenia. It constitutes essential reading for information security specialists, researchers and professionals working in the area of computer science and communication systems.

Today, more than 80% of the data transmitted over networks and archived on our computers, tablets, cell phones or clouds is multimedia data – images, videos, audio, 3D data. The applications of this data range from video games to healthcare, and include computer-aided design, video surveillance and biometrics. It is becoming increasingly urgent to secure this data, not only during transmission and archiving, but also during its retrieval and use. Indeed, in today’s "all-digital" world, it is becoming ever-easier to copy data, view it unrightfully, steal it or falsify it. Multimedia Security 2 analyzes issues relating to biometrics, protection, integrity and encryption of multimedia data. It also covers aspects such as crypto-compression of images and videos, homomorphic encryption, data hiding in the encrypted domain and secret sharing.

Communications and Multimedia Security is an essential reference for both academic and professional researchers in the fields of Communications and Multimedia Security. This state-of-the-art volume presents the proceedings of the Eighth Annual IFIP TC-6 TC-11 Conference on Communications and Multimedia Security, September 2004, in Windermere, UK. The papers presented here represent the very latest developments in security research from leading people in the field. The papers explore a wide variety of subjects including privacy protection and trust negotiation, mobile security, applied cryptography, and security of communication protocols. Of special interest are several papers which addressed security in the Microsoft .Net architecture, and the threats that builders of web service applications need to be aware of. The papers were a result of research sponsored by Microsoft at five European University research centers. This collection will be important not only for multimedia security experts and researchers, but also for all teachers and administrators interested in communications security.

This book constitutes the refereed proceedings of the 7th IFIP International Conference on Communications and Multimedia Security, CMS 2003, held in Torino, Italy in October 2003. The 21 revised full papers presented were carefully reviewed and selected for presentation. The papers are organized in topical sections on cryptography, network security, mobile and wireless network security, trust and privacy, application security, and multimedia security.

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.
