A DWT-based digital video watermarking scheme with error correcting code

Abstract

In this paper, a digital video watermarking algorithm is proposed. We present a novel DWT-based blind digital video watermarking scheme with scrambled watermark and error correcting code. Our scheme embeds different parts of a single watermark into different scenes of a video under the wavelet domain. To increase robustness of the scheme, the watermark is refined by the error correcting code, while the correcting code is embedded as watermark in audio channel. Our video watermarking algorithm is robust against the attacks of frame dropping, averaging and statistical analysis, which were not solved effectively in the past. Furthermore, it allows blind retrieval of embedded watermark which does not need the original video; and the watermark is perceptually invisible. The algorithm design, evaluation, and experimentation of the proposed scheme are described in this paper. © Springer-Verlag Berlin Heidelberg 2003.
