Abstract

This article reports a pioneer work on a steganography scheme in the domain of side-match vector quantization. The challenge associated with dynamic state code books had been resolved by two possible alternatives, namely code book partition by code words' mean and code book partition by pseudo random sequence. Experiment results reveal that imperceptibility required for secret communication can be ensured with the proposed approaches.
