Abstract:
In this work we have introduced a new watermarking algorithm for securing video images. We have decomposed the bit planes where the monochrome watermark is given the video frame colour channels. We further inserted a CB-SVD algorithm with a reduced cyclic scheme and used to insert the watermark. Reduced insertion scheme reduces the level of degradation of video while simultaneously extracting a high quality watermark. The proposed RCB-SVD algorithm has no deficiency for detection of a false watermark, as is the case with standard SVD algorithms. The builtin redundancy of the reduced cyclical insertion scheme increases the resistance to â€œframe-droppingâ€ attacks. When we compared with earlier outcome, the repair of the extracted watermark was achieved by a good margin.
