Abstract

Bit streams of scalable coded media are adapted at various nodes in multimedia usage chains to cater the variations in network bandwidths, display device resolutions and resources and usage preferences. This is achieved by extracting the most relevant segments from the scalable coded bit stream corresponding to the quality-resolution requirements. Such adaptations can affect the watermarking information embedded in the content and can result in errors in extracting and authentication of such watermark data. A framework for evaluating watermarking robustness to JPEG2000 based content adaptation attacks is presented. The proposed framework represents commonly used wavelet based watermarking algorithms as a subset of a general watermarking framework and simulates the content adaptation modes based on JPEG2000 transcoding to provide a general framework for evaluating watermark robustness in such adaptations and the influence of different embedding modes.
