A new combined video content protection approach is proposed and experimentally evaluated. In this approach reliability information obtained during watermark extraction process is used for improving the accuracy of traitor tracing procedure.
The authors consider two new attacks on watermarked video specific to HD 60 fps H.264 High and Main profiles: selective I/P frames' removal and zeroing of residuals in B frames. We propose the method of embedding of a readable watermark for H.264 High Profile video robust to such attacks. The video stream is partially decoded removing entropy coding, then a… (More)
