Abstract

Watermarking is one useful solution for digital rights management (DRM) systems. In this paper, in addition to following conventional objectives to conquer against intentional or unintentional attacks, we not only watch the survivability of embedded watermark, but also focus on retaining the watermarked image quality with the aid of multiple description coding (MDC). MDC is an algorithm for error resilient coding, suitable for transmitting compressed data over multiple channels. In this paper, we propose an innovative algorithm on vector quantization (VQ) based image watermarking, which is suitable for error-resilient transmission over noisy channels. By incorporating watermarking with multiple description coding, the scheme we proposed for embedding three watermarks can effectively overcome channel impairments while retaining the capability for copyright and ownership protection. With the promising simulation results presented, we can demonstrate the utility and practicability of our algorithm.
