Abstract :
An adaptive compressed domain watermarking method is proposed in the paper. In this technique, multiple binary images derived from a single watermark image are first embedded in a video sequence. The spatial spread spectrum watermark is directly incorporated in the compressed bit streams by modifying the wavelet coefficients. Experimental evidence demonstrates that the developed approach is efficient and also robust against spatial attacks such as scaling and frame averaging, and temporal attacks like frame dropping and shifting.
