Audio watermarking with HOS-based cepstrum feature

TLDR: A more robust scheme of audio watermarking which is based on cepstrum (or cepstral coefficients) and HOS (higher-order statistics) schemes is proposed, which could outperform the previous innovative one.

Abstract: In this paper, we propose a more robust scheme of audio watermarking which is based on cepstrum (or cepstral coefficients) and HOS (higher-order statistics) schemes. This scheme is a zero-watermarking one for the reason to maintain the audio quality. The audio signal is firstly kurtosis-estimated and feature-recognized, and then analyzed via CC and HOS, respectively, to extract the essential parameters and characteristics, which are then used for information embedding and extracting. The achievement of the proposed scheme could outperform the previous innovative one [1].
