Multimedia content adaptation enables users with different access networks, client devices, and/or user profiles to access the same information source. However, content adaptation also introduces security implications. We conduct an in-depth investigation into the potential security issues involved and analyze general security architectures and requirements. In particular, we address the issue of where to place the securityfunctions and how this affects functionality.

Content adaptation has been introduced to tailor the same media content to different derived user contexts to allow end users with different access networks, client devices and/or user profiles to access the same information source. However, content adaptation also introduces security implications in a content distribution food chain. In this paper, we conduct an in-depth investigation into the potential security issues involved in content adaptation, especially video content adaptation, in multimedia communication systems. We analyze the security requirements in the context of content adaptation. In particular, we address the issue of where to place the securityfunctions and its implications on the security and content adaptation functionality. The general security architectures for the protection of adapted content are categorized and analyzed. Various rationales and implications of some of the most recent multimedia security technologies are investigated under these architectures. The paper provides the readers with an in-depth analysis, a comprehensive overview, and a better understanding of the security issues in a multimedia communication system where adaptation is a necessity.
