PDF-Version of the Proceedings
Recently security has become one of the most significant problems for spreading new information technology. Digital data can easily be copied and multiplied without information loss. This requires security solutions for such fields as distributed production processes and electronic commerce, since the producers seek to provide access control mechanisms to prevent misuse and theft of material. 
The workshop analyses specific security problems of multimedia systems and multimedia material in the digital environment. Additionally we address the topic, that existing multimedia security mechanisms are not realized by using multimedia tools applying security. Thus the discussion is extend to the use of multimedia to perform security. 


The objective is to bring together researchers, developers, and practitioners from academia and industry for a state of the art evaluation and discussions of topics for multimedia security environments for the next century. The workshop intends to reflect on strength and weaknesses of what the multimedia community has to offer to meet the needs of secure multimedia environments.

A major field of the discussion is the identification of acceptance problems to use  distributed multimedia production systems and digital marketplaces. 
Solutions for confidential transmission, authentication of original, copyright protection and Try&Buy transactions will be addressed. 
Though security is recognized as an important issue in multimedia it is, ironically, mostly not presented by the new media. Usually, security algorithms are seen as background processes, invisible to the user. Based on the discussions on security in multimedia environments we analyze interactive multimedia tools which strengthen the producers acceptance to use available security features. As an example we present an approach to an interactive watermarking environment to ensure copyrights. We show the need for a flexible and open watermarking environment for embedding robust watermarks. 
We will focus  on the lack of media support as well as on the definition of new design criteria for multimedia security environments. 
The intention of the workshop is to provide space for intensive discussions among the addressed problems of security in and with multimedia. We show current solutions and still open problems which must be ad-dressed in the near future.
