Abstract

Heterogeneity among the end using display devices and corresponding varying system requirements make scalable version of H.264/AVC standard more popular. Existing watermarking based authentication system may not be suitable well for this new extension, because the scalability property of the codec may itself is perceived as an attack popularly known as content adaptation attack. In this paper, a blind scalable video watermarking scheme is proposed, which is robust against quality and temporal scalability. In the proposed scheme, Discrete Cosine Transform (DCT) based temporal filtering and wavelet based spatial filtering is used for choosing suitable watermark embedding zone. Experimental evidences are provided to justify the improved robustness of the proposed scheme over existing related watermarking schemes. The visual quality of the watermarked video has also been evaluated to show the efficiency of the proposed scheme.
