Abstract

With the emerging technology of the MPEG-4 XMT standard, highly and efficiently compressed MPEG-4 scenes, which can include images, video, audio, and 3D objects, can be easily built using the text-based XMT format. XMT allows content authors to exchange their content with other authors, tools, or service providers and facilitates interoperability with MPEG-4, X3D and SMIL. In order for authors and designers to protect their work, some form of security needs to be applied to the MPEG-4 XMT structure. Unlike images or videos, watermarking an XMT structure is not an easy task, since the structure contains no noise components to embed the watermark, and if the watermark was embedded, it can be easily detected and removed. This paper is the first one proposing a novel robust algorithm for authentication and protection of MPEG-4 XMT structured scenes.
