스프레드 스펙트럼 기반 디지털 오디오 워터마킹 기법 연구
Digital Audio Watermarking Based on Spread Spectrum Techniques
초록
In this paper, we propose a robust audio watermarking method. The proposed watermarking algorithm is composed of a psychoacoustic model to achieve perceptual transparency and spread spectrum technique to embed watermark. The watermark is embedded in each audio frame by adding a perceptually-shaped pseudo-random sequence. We demonstrate the robustness of the watermarking algorithm.
