Security has become one of the most significant and challenging problems for spreading new information technology. Digital data can easily be copied and multiplied without information loss as well as manipulated without any detection. This requires security solutions, which encounter these threats. Security solution are especially of interest for such fields as distributed production processes and electronic commerce, since their producers provide only access control mechanisms to prevent misuse and theft of material. By increasing both the requirements for efficiency and the possibilities of IT-systems, the needs for security and trustworthiness also enlarges. These needs are particularly important for security-relevant applications as well as for applications processing sensitive personal data. IT-systems are commonly used for different kinds of applications, increasingly applications dedicated to multimedia. Obviously, secure and trustworthy actions and interactions are very important requirements for multimedia systems.

The workshop analyses specific security problems of multimedia systems and multimedia material in the digital environment. Based on our discussion during the workshop at the ACM MM 98 in Bristol and at the ACM MM 99 in Orlando, we want to continue with the state of the art evaluation and discuss future needs for the design of MM Security and legal aspects. We understand that the interest and importance of security was reflected in the great number of participants from all over the world in the last two workshops. 
Based on these excellent experiences, the objective of the workshop is to see the advantages in the field of multimedia and security. The intention of the workshop is to bring together experienced researchers, developers, and practitioners from academia and industry for a state of the art evaluation and discussions of topics and problems for multimedia security environments for our new century. The workshop reflects the strength and weaknesses of what the multimedia community has to offer to meet the needs of secure multimedia environments. The participants will get an excellent overview about what the community has to offer, where are the improvements, the progress, and the problems.

Initially, the progress of digital watermarking will be presented. We want to classify digital watermarking techniques, their applications and fundamental parameter. In addition, we introduce new fragile watermarking systems which ensure manipulation recognition. Here, we distinguish between content-preserving and content-manipulating changes. 
In the field of copyright protection, we want to discuss robustness, security, and the usage of public-key solutions. Existing multimedia security mechanisms use steganographic approaches and are mostly not realized by cryptographic solutions applying security. Thus, the discussion is extend to the use of cryptographic mechanisms.

We want to  face the topic of the use of digital sig-natures for authentication. Furthermore, problems deriving from the usage of public-key certificates within security infrastructures will be discussed. Additionally, attribute certificates are introduced, which can be used excellent for customer specific profiles.
Beside technical approaches, legal requirements, the identification of design, and acceptance problems of security solutions are addressed.  Finally, multimedia applications are presented, e.g. within the field of electronic commerce where security solutions are of main interest.

This year we have four invited talks:

  • Edward J. Delp, Video and Image Processing Laboratory (VIPER) School of Electrical and Computer Engineering Purdue University West Lafayette, Indiana USA: Watermarking with Applications in Internet Media Streaming
  • Ton Kalker, Philips Research Laboratories, Eindhoven, The Netherlands: Audio Water-marking for Monitoring and Copy Protection
  • Adnan Alattar, Digimarc Corporation: Bridging Printed Media and the Internet via Digimarc's Watermarking Technology
  • Klaus Keus, BSI, Germany: Legal aspects of digital signatures and watermarking

and a call for papers to include other reviewed papers for a day-long workshop to related topics such as but nit limited to

  • copyright protection
  • robust and fragile watermarking techniques
  • watermarking attacks
  • visual models
  • quality evaluations and benchmarks
  • conditional access
  • content-based digital signatures
  • leagl apspects
  • watermarking protocols
  • secuirty in JPEG2000, MPEG-4, MPEG-7 or MPEG21
  • biometrics and multimedia secuirty
  • video and audio crypting
  • watermarking applications
How to submit? Please see above. The papers (page limit is 4 pages) will be published by ACM in an extra workshop proceeding. We plan to publish a longer version (up to 12 pages) in a GMD publication. The workshop fee will be $100 for ACM members and $120 for non-members.
