Multiple description watermarking for lossy network

The paper proposes an innovative watermarking scheme based on vector quantization (VQ); it is suitable for media transmission over noisy channels with multiple description coding (MDC). Digital watermarking is one of the applicable tools that can be used to protect digital contents from illegal copying and distribution. In addition to conventional schemes that apply attacks on watermarked media, we focus our application on transmitting over noisy channels to consider both the error-resilient transmission of watermarked media, and the robustness of the watermarking algorithm. By modifying the multiple description vector quantization (MDVQ) algorithm for watermark embedding and extraction, simulation results not only demonstrate the effective transmission of a watermarked image, but reveal the robustness of the extracted watermark.
