2009 International Workshop on Secure Multimedia Communication and Services (SECMCS'09)

Introduction The rapid development of communication techniques allows us to transmit more than text/binary data in real time. While multimedia (image, video, audio, etc.) enriches human's daily life, its prosperity also attract malicious attackers and abusers with different motivations, such as political reasons, illegal financial benefits, or simply to win a prestige reputation in a hacker community. Nowadays, multimedia communication plays an important role in multiple areas in human society including entertainment, politics, economics, militaries, industries, etc. It is urgent to secure multimedia data by providing confidentiality, integrity, and ownership or identity. In the past decade, multimedia security has been a hot topic in the security research community. Various solutions have been reported, which address problems including data encryption, multimedia authentication, digital rights management (DRM), etc. However, due to some characteristics of multimedia content, such as large data volumes, interactive operations, and requires real-time responses, the problems multimedia security need to address are different from text/binary data security. Furthermore, multimedia security is highly services-dependable. Different services require different methods for content transmission or distribution, paying, interaction, etc. Particularly, new services have been emerging and new techniques are appearing, such as mobile TV, IPTV, IMS, VoIP, P2P living or download, convergence of mobile and Internet, etc. For instance, in mobile TV, the terminal's power should be considered when designing security functions; in P2P living, the requirement in a distributed architecture is different from the server-client mode. Additionally, multimedia content filtering should be considered to clean up the service system. Under the environment of network convergence, the smart means adaptive to different networks are expected. This workshop aims to bring together research work in the area of secure multimedia communication, investigate the novel solutions for secure multimedia services, and discuss the future trends for multimedia security in new services.
